2. Core Functions

1. AC-DC Power Conversion & Regulated Power Distribution Accepts AC input from the rack power source, converts and stabilizes multi-channel DC output. It supplies clean, low-ripple regulated power to the main controller, I/O cards and communication boards inside the DCS rack, with galvanic isolation between input and output circuits.
2. Multi-dimensional Electrical Protection Integrates overvoltage, undervoltage, overcurrent, overload, short-circuit and surge protection circuits. It automatically cuts off power or triggers alarm once abnormal electrical conditions are detected to protect the whole DCS rack from damage.
3. Power Status Monitoring & On-board Diagnostics Continuously monitors input voltage, output rail voltage and load current. LED status indicators show normal operation, power loss or fault status. It reports power failure / fault signals to the DCS main controller for system alarm logging.
4. Power Sequence Control Manages the power-up and power-down sequence of all modules in the control cabinet. It ensures the controller and I/O cards are energized in the correct order to avoid data corruption and hardware damage during startup and shutdown.www.plcva.com
5. EMC Noise Suppression Built-in EMI filter circuits to suppress electromagnetic interference in heavy industrial environments, maintaining stable power quality for sensitive DCS electronic components.
