1. Functions

1. AC-DC multi-rail power conversion & voltage regulation It converts input mains AC power into multiple stabilized DC output rails (+5V, ±12V, 24V and auxiliary standby voltage). It supplies clean, well-regulated power for the equipment’s CPU board, sensor circuits, I/O modules and communication boards.More products: www.plcva.com
2. Power sequencing & soft start control Implements controlled power-up sequence. It enables different voltage rails in a predefined time order to avoid surge current, preventing damage to sensitive digital and analog control circuits on the equipment backplane.
3. Overvoltage, overcurrent and overtemperature protection Onboard monitoring circuits continuously sample output voltage, load current and board temperature. It triggers shutdown / latch-off protection automatically once parameters exceed threshold values to safeguard downstream electronics.
4. Power status monitoring & fault reporting Built-in voltage monitoring circuits generate power-good signals and fault alarm signals. It feeds power status back to the system main controller; alarms will be sent to HMI upon power failure or abnormality.
5. Filtering and noise suppression Integrated EMI filtering circuits suppress input power surge and high-frequency noise, reducing interference to precision analog sensors and low-level signal circuits in the process chamber.plcva.com
