Powertek's Lightweight Frequency Converter and AC Power Sources

Front View

Powertek frequency converters are high-reliability power sources that can operate on any common input voltage and frequency worldwide, and deliver stable, isolated pure sinewave AC Output. They are specifically designed for demanding applications in high shock, vibration and humidity environments. They can be built to meet MIL-STD-810, MIL-STD-1399, MIL-STD-1472, MIL-STD-461, and other standards optionally. These models utilize high frequency PWM topology, offering significant volume and weight advantages suitable for severe environment and high reliability applications such as:
