Product Functions
Rectification and Filtering:
ABB 500PSM03A input AC power is converted into high-voltage DC through a bridge rectifier, then smoothed by electrolytic capacitors.
High-Frequency Switching:
ABB 500PSM03A internal controller drives MOSFET switching transistors to chop the DC voltage into high-frequency pulses, achieving electrical isolation and voltage transformation via a transformer.
Secondary Rectification and Voltage Regulation:
ABB 500PSM03A high-frequency pulses from the transformer's secondary output are rectified by fast diodes and processed through an LC filter to produce a stable 24VDC output.
Feedback Control:
ABB 500PSM03A output voltage is fed back to the controller via an optocoupler, dynamically adjusting the switching transistor's duty cycle to ensure output accuracy.
