Overview of Smart Power Supply Systems for the LED Display application

In the world of  LED displays, “resiliency and redundancy” is a buzz word especially for critical applications such as live broadcasts television, or digital out-of-home–where every minute of up-time is sponsored.  The power system, and in particularly the power supply unit (PSU) is an area susceptible to failures and continues to be an area of innovation for designers.

Even with a MTBF (Mean Time Between Failure) of 207,000 hours (MIL-HDBK-217F (25c) on a Meanwell SP320-5–a commonly used PSU–there remains a slight probability of outage due to normal wear and tear, operating in non-lab environments, outlier events, or unpredictable external factors such as a power surge or weather related events.

Most displays on the market today (2013) are not equipped with any smart power system.  Thus, if and when a PSU goes down, the LED tiles they drive will inevitably go dark. Most designs allow each PSU to drive 3 to 6 tiles, based on the pitch, tile size and power consumption of each tile. This means up to 6 tiles would go out in a chain of dark line across the screen.

The lack of resiliency is apparent on industry leader Daktronic’s product webpage:

“Fully Sealed, 2-to-1 Power Supplies
We dedicate one fully sealed, internally mounted power supply to every two digital billboard modules, making installation easier and rear servicing more convenient. Your message remains readable even if a power supply fails because the failed power supply only affects two modules. Other LED digital billboard distributors may have a single power supply delivering power to large groups of modules. When a power supply fails, it affects a vast section of a digital billboard and the advertisement becomes unreadable.”

This reveals that if a PSU goes out, 2 LED tiles will be affected on a Daktronics system. This is an advantage over others that drive more than 2 tiles per PSU resulting in a larger area being affected.

With resiliency implemented, any dark spots on a screen can be eliminated. As soon as one PSU goes down, the backup source is immediately activated. This switch over is instantaneous and without any visible delay. The probability of a black out, approaches zero as it’s related to the probability of two or three PSUs going out at the same time. Even in the extreme unlikely event that multiple PSUs go out simultaneously, the feedback and intelligence function will reduce the power draw requirement of the affect screen area proportionally, so the area is dimmed, but never goes completely dark.  This concept will be covered in upcoming white papers.

2-1 Backup:
Every PSU is paired with a backup unit.  This is the most straightforward approach, but the downside is that weight of each LED panel is increased considerably. Assume there are 4 PSUs per a 3×4′ (1×1.2m) panel and 4 lbs per PSU on average would result in a total increase of 8 lbs per panel. Cost of additional PSU also needs to be factored, in but the benefits should outweigh the cost incurred from down time on the screen in the field.

Feedback:
Another concept that goes hand in hand with “resiliency” is the “feedback” mechanism.  As a PSU goes out, the feedback is activated, and the service team will be made aware of it’s existence. The location of the down PSU is also identified for a scheduled, proactive, targeted and swift maintenance event.

Small Business Administration Endorses LED Signs

SBA study on Outdoor LED Signs: 15-150% increase in business!

The Small Business Administration cites signs as the most effective, yet least expensive form of advertis­ing for small businesses. More specifically, with an LED sign the cost per thousand impressions (CPT) is as little as 15 cents.  Also, a small business enhancing their signage with an LED sign can see an increase in business from 15-150%.

For example, a business that makes $1,000 a day in gross income adds an LED sign. Traffic quickly increases by the minimum 15%, adding $150 per day in total sales. This turns into an additional $1,050 a week, or $54,600 a year. If using the 150% estimate, the weekly increase in sales becomes $10,050 or $546,000 a year!

Businesses often select their advertising medium based upon the CPT exposures to the public. No other form of advertising comes close to matching the efficiency and cost-effectiveness, dollar for dollar, of an LED sign:

• Newspapers – On average, the cost is about $7.39 per 1000 exposures
• Television – On average, the cost is about $6.26 for 1000 exposures.
• Radio – About $5.47 for 1000 exposures.
• New LED display – Less than $0.15 for 1000 exposures.

For example, if you invest $10,000 on an LED sign with a life span of ten years, the amortized cost on a daily basis is about $0.91. Add the daily electricity fee (approximately $0.20), giving your LED sign expense total of $1.11. If daily vehicle traffic (passing your sign) is 20,000, your cost would be less than $0.15 per 1000 exposures (and that’s counting drivers only)!

The best part is, with an LED sign, you don’t have to worry about missing the target audience, becoming yesterday’s news, or having production fees to change the promotion–which can be costly with TV, radio and newspapers.

With an LED sign, you own the advertising medium. It works 24 hours a day and performs as a very reliable and highly visible salesman; drawing eye-ball off the street and attracting the 80% potential customers who live, play, and commute with a 10 mile radius of your business.

The custom tailored message speaks straight to the potential customer as they pass by your company’s location, and the LED sign makes your company a landmark in the community showing weather and PSA announcements.

(Baltimore, MD) – Amtrak has given Downtown Partnership of Baltimore and Visit Baltimore permission to proceed with plans to install new landscaping and a video welcome sign on the track level of Baltimore’s Pennsylvania Station.

The project will have four components: a large “Baltimore” sign; a cutting-edge screen to show promotional videos about Baltimore; new landscaping for the hill on the north side of the tracks; and attractive new fencing at the top of the hill. Much of the design has been done and fabrication of the signage and video screen base are set to begin. Installation of the project is expected to be completed in 2013. (NOTE: Images are below)

The project is being funded jointly by Downtown Partnership and Visit Baltimore. Other partners include Amtrak, the Central Baltimore Partnership and the Charles Street Development Corporation. The contractors are Mahan Rykiel (landscape architects); Gutierrez Studios (design concept and fabrication of the sign and video mount); EBA engineering, and NV3 (video consultation) in conjunction with LED Media Group/QST-North America. “Penn Station is a major gateway and the all-important first impression of our city for tens of thousands of passengers each year,” said Kirby Fowler, President of Downtown Partnership of Baltimore.  “We looked at the overall quality of that experience and felt this is something we can do in the near term to improve it.”  “When train passengers look up as they arrive at our station, they currently see a barren hill. We saw an opportunity to improve that experience by welcoming travelers and creating video signage that will convey positive news and images about Baltimore,” said Tom Noonan, President and CEO of Visit Baltimore. “There is no overstating the value of that first impression as travelers pull into the station.”

The public-private initiative led by Downtown Partnership and Visit Baltimore is a creative and welcome way to enhance Baltimore’s Pennsylvania Station as my administration pursues longer-term capital improvements with Amtrak and our Federal representatives in Congress,” said Baltimore Mayor Stephanie Rawlings-Blake.  “Baltimore is an important city along the Northeast Corridor and we are pleased to work with our local partners to make this attractive improvement possible for visiting passengers,” said Amtrak President and CEO Joe Boardman. Baltimore Penn Station is the eighth busiest station in the Amtrak national network and growing.  In the fiscal year ending September 30, more than one million passengers traveled  through the station, which represents an increase of 7.9 percent over the prior year.

Downtown Partnership is a nonprofit corporation working with the public and private sectors to make Downtown Baltimore a great place for businesses, employees, residents, and visitors. The Partnership’s policies and programs have led to a cleaner & safer Downtown, to an increase in housing and retail opportunities, to the retention of key employers, to the development of solutions to transportation challenges, and to increased public and private investments in the area.  Visit

Smart Power Supply: Achieving 100% uptime in the LED Display application.

In-field power supply failure is a major cause of downtime in LED Displays. This is especially a critical problem in the Digital Outdoor and Live Broadcast applications. This white paper explores the technologies available to achieve 100% power supply up time that are now available in the market.

In the world of  LED displays, “resiliency and redundancy” are buzz words for critical applications such as broadcast TV, and digital out-of-home–-where every minute of uptime is sponsored. The power system, and in particularly the power supply unit (PSU) is an area susceptible to failures and continues to be an area of innovation for designers.

According to Meanwell, an industry leading Power Supply provider, the MTBF¹ (Mean Time Between Failures) on the widely used SP320-5 is 207,000 hours. (MIL-HDBK-217F (25°) There still remains a probability of outage due to normal wear and tear, operating in non-laboratory environments, outlier events, or unpredictable external factors such as a power surge or unpredictable weather related events.

Most displays on the market today (2013) are not equipped with any resilient power system. Thus, if and when a PSU goes out, the LED tiles which it drives will inevitably go dark. Most designs use one PSU to drive 3 to 6 tiles, based on screen pitch, tile size and power consumption of each tile. This means up to 6 tiles would go out in a chain of dark line across the screen when a failure occurs.

Smart Power Supplies

According to industry leader Daktronic’s product page:²

“Fully Sealed, 2-to-1 Power Supplies
… Your message remains readable even if a power supply fails because the failed power supply only affects two modules. Other LED digital billboard distributors may have a single power supply delivering power to large groups of modules. When a power supply fails, it affects a vast section of a digital billboard and the advertisement becomes unreadable.”

What this tells us is that if a PSU goes out on a Daktronics system, 2 LED tiles will be affected. This is an advantage over others that drive more than 2 tiles per PSU.

With resiliency implemented, any dark tile on a screen due to power can be eliminated. As soon as one PSU goes down, the back up source is immediately activated. This switch over is instantaneous and without any visible interruption to the audience. The probability of a black tile, approaches to zero as it’s correlated to the probability of two or three PSUs going out at the same time. Even in the extreme unlikely event that multiple PSUs go out simultaneously, the feedback and intelligence function will reduce the power draw requirement and dim the affected screen area so the area is dimmed, but never goes completely dark.

QST Smart PSU and Control System

QST Smart PSU and Control Diagram

Key Concepts:

2-1 Backup:
Every single PSU is paired with a backup unit.  This is the most straightforward approach but the weight of panel and increased cost is the tradeoff. Assume there are 4 PSUs per a 3×4′ (1×1.2m) panel and 4 lbs per PSU on average would result in a total increase of 16 lbs per panel. Cost of additional PSU needs to be factored in but the benefits should outweigh the cost incurred from down time on the screen.

n+1 Backup:
This setup is where a group of say 4 or 5 power supply is used in tandem with a backup unit (in which case would be 4 or 5 + 1). An intelligent feedback system is activated to monitor the number of active PSUs.  If one PSU goes out, the redundant grid isn’t affected as there’s ample overhead.  In the extremely unlikely case that more than 2-3 units goes out at the same time, the intelligence on the Smart system can reduce the screen brightness of the affected area to say–50% and thus reducing the overall load. The cost adders and weight increase of the the n+1 solution is marginal and thus by far it’s the most advanced in the market.

Feedback:
A component that goes hand in hand with “resiliency” is the “feedback” mechanism.  As a PSU goes out, feedback is activated, and the service provider is made aware of the outage. The location and exact number of the PSU is also proactively identified so that a scheduled, targeted and swift maintenance event can be made. Feedback is commonly delivered by email or sms.

Intelligence:
The mechanism by which the control system of the display works in conjunction with the PSUs to reduce the brightness of the affected area or to activate PSUs on reserve.
