AC DC Converters

Power Conditioning Modules (PCM) are specialized electronic components that convert AC power to DC power. They are widely used in industrial and commercial applications such as lighting control, ventilation, inverters, and UPSs. The PCM-400-28-CFS is a type of PCM specifically designed for industrial applications. It is able to convert 400V AC input to a 28V DC output.

Application Field

The PCM-400-28-CFS is designed for use in industrial applications such as HVAC, computer servers, power supply, inverters, and UPSs. It is also suitable for automotive applications, including power steering, engine control, and throttle control. This particular PCM module is designed to offer high efficiency and reliability in a wide range of applications.

Working Principle

The PCM-400-28-CFS uses pulse width modulation (PWM) to control the output voltage. A PWM IC controls the duty cycle of an AC waveform by switching on and off an electronic device at a specified frequency. The resulting waveform has varying duty cycles which translates into an AC waveform with a fixed average value and varying peak values. By using a secondary power transformer, this waveform is then converted into a DC voltage. The transformer also serves to isolate the input from the output, providing better protection and greater reliability.

This PCM module provides a unique combination of high efficiency, precise control, and extremely small size. Its integrated components make the PCM-400-28-CFS a simple, cost-effective solution for a variety of industrial applications.
