The electrolytic capacitor is the weak point of every power supply: its liquid electrolyte dries out and limits the lifetime to a few years. Power supplies without electrolytic capacitors use film capacitors and digital control - for a calculated lifetime of 70 years and maintenance-free operation.

A study shows that 52% of all LED streetlight failures are caused by the power supply - only 10% by the LEDs themselves. The key to long-lasting LED luminaires lies in the power supply.

Many confuse MTBF (Mean Time Between Failures) with the actual lifetime of a power supply. This article explains the crucial difference and what criteria really matter.

This article develops a vision of the future from the history of power supplies: from iron-core transformers through high-frequency switched-mode designs to software-defined digital power.

In Digital Power, a microprocessor takes over the complete control of the power supply. This enables IoT capability, predictive maintenance, flexible configuration, and exceptional longevity.

Virtually no electronic circuit works without capacitors. But how do the different types compare in terms of lifetime and reliability? A comprehensive comparison.

Selecting an LED power supply is straightforward if you know what to look for. Our CEO Dr. Michael Heidinger explains the fundamentals: constant current vs. constant voltage, power calculation, and lifetime considerations.

Electrolytic capacitors are the most common cause of power supply failures. Discover how innovative power supply designs without electrolytic capacitors solve this problem and achieve lifetimes exceeding 70 years.
