The Power To Perform

Power supply failures in mission-critical AV products can cause significant disruption to signal distribution and facility operations, creating serious challenges for system integrators, end users, and manufacturers alike. Extron has answered this challenge with the Everlast™ Series of high-performance, no compromise, internal and external power supplies, setting a new standard for reliability and efficiency in the professional AV industry.

Designed from the ground up by our Extron engineering team, Everlast Power Supplies use state-of-the-art technology and the highest-quality components to ensure extreme reliability in commercial AV products including Digital Matrix Switchers, Videowall Processors, Distribution Amplifiers, Scalers, Control Systems, and more. Like all of Extron’s products, our design philosophy and manufacturing process for the Everlast Power Supplies are driven by safety, performance, reliability, and efficiency, not merely by cost.

Extron’s Vector 4K Scaler

AV hardware manufacturers typically use generic off-the-shelf power supplies from 3rd party vendors. These mass-produced power supplies are frequently designed to meet a low price point, employing the least expensive components meeting the minimum manufacturing spec. Using a plastic fan assembly instead of a superior metal alternative, or a cheap diode vs. an efficient transistor, or a 10 cent capacitor instead of a 20 cent version might save some pennies in manufacturing costs, but those savings can turn into expensive liabilities when the product fails to power up. These high-volume, low-cost power supplies often employ older design principles and dated topologies.

For example, the older mechanical methods for thermal management typically used in the industry require a combination of heat sinks, insulators, washers, and screws. This approach adds complexity and introduces many potential points of failure to the power supply. A more modern approach, used by Extron, uses the PCB copper area as a heat sink for surface mounted transistors and diodes.

We design and manufacture our Everlast Power Supplies in-house, employing premium-quality components and highly efficient, modern topologies for thermal management, transistor switching, energy dissipation, and virtually every other critical aspect of the power system. Each Everlast Power Supply is built with the same care and meticulous attention to detail as our award-winning high-end video products.

Thermal Management

Traditional Approach
High operating temperatures adversely impact component performance and longevity. Traditional designs often require the mounting of a transistor to a dedicated heatsink. Due to repeated thermal expansion and contraction, a compression washer and locking nut must be used to ensure proper force is applied to the thermal insulator. This older, complex approach can be susceptible to shock and vibration, causing broken leads.

The Everlast Approach
Extron’s approach to heat dissipation leverages our expertise in Printed Circuit Board - PCB technology to surface mount and heat sink our power packages. This method is dependable and consistently repeatable, as it removes all hand labor and human error from the process. The result is a highly reliable procedure that is far less susceptible to shock and vibration.

Resonant Soft Switching

The "hard switching" converters common in most professional AV power supplies cause significant transistor loss. Smaller transistors must be used, which adversely impacts performance and efficiency. The resonant soft switching design in our Everlast Power Supplies enables Extron to use larger transistors, which operate more efficiently by reducing conduction loss and minimizing waste heat.

Superior Fan Technology

For Everlast Power Supplies, our engineers select high quality metal frame fans with ball bearings that have long MTBF specifications and run them at low RPM. This increases fan life, with the added benefit of reducing noise. The end result is a quieter, more durable solution than the high-speed, noisy plastic fans used in competitors’ products.

Large Transformers

Larger magnetics enable the power supply to run cooler and more reliably. By using larger transformers, Everlast Power Supplies generate less waste heat than competitors’ power supplies, creating a more efficient and dependable solution.

Synchronous Rectifier FET

Everlast Power Supplies employ synchronous rectifier FETs (Field Effect Transistors) instead of inexpensive diodes. This reduces waste heat, which contributes considerably to system longevity.

Active Start-up Circuitry

Typical power supplies use a resistor in the start-up circuitry to supply start-up power to the 12V control system from the AC line voltage. This is an inefficient approach, as the resistor continues to dissipate power unnecessarily for the life of the product. Everlast Power Supplies replace the resistors in the start-up circuitry with a more expensive transistor, creating a highly efficient, “active” solution.

Resonant Clamp Topology

The converters in traditional power supplies dissipate the unavoidable, unwanted stored energy through a “dissipative clamp circuit” comprised of a diode and capacitor. Extron Everlast Power Supplies employ a resonant clamp design, which recycles the clamp energy in a nearly lossless way. This modern approach enables the transformers to maximize the stored energy rather than minimize it.


To further ensure long-term reliability, each Extron Everlast Power Supply goes through an extensive 8-hour burn-in process to immediately uncover and eliminate any manufacturing issues or component defects. Our pride in the quality and durability of our power supplies gives us the confidence to offer our customers an unprecedented 7-year warranty on all Everlast Power Supplies.

Demonstrated Reliability. Proven Performance.

Typical AV power supplies have an average MTBF, Mean Time Between Failure, rating of around 30,000 hours, calculated by using the stated specifications of the individual components.

To ensure that our Everlast power supplies meet Extron standards of performance and quality, we subjected each model of our PS Desktop Series to actual, not calculated, accelerated operational life testing, using a heat chamber at an ambient temperature of 85° C. The power supplies were operated under load for over 2 years. Under these grueling conditions, each hour in the heat chamber is like 64 hours in the real world.

Based on this actual accelerated operational life testing, we achieved MTBF benchmarks of 280,000 hours up to an incredible 1,000,000 hours, or the equivalent of over 114 years, depending on the model. We know of no other company that has gone to such lengths to guarantee power supply reliability. Simply put, our Everlast Power Supplies deliver unprecedented, demonstrated reliability and longevity in the most demanding professional AV environments.

DEMONSTRATED MTBF (Mean Time Between Failure)

The energy efficient designs of our Everlast Power Supplies help to meet green building requirements by lowering power consumption and reducing overall operating costs.

  • Our Everlast PS Series of Desktop Power Supplies are Level VI rated and consume just 0.075 watts or less at idle when no load is present on the output.
  • Our superior heat dissipation and thermal management engineering enables Everlast power supplies to run cooler than less efficient power supplies at the same load.
  • The remarkable longevity of our Everlast Power Supplies greatly reduces the need for field replacements, resulting in far fewer out-of-service power supplies winding up in landfills.
