IV. Working Principle
GE IC698PSD300C is a dedicated 300W rack-mounted regulated power supply module for PACSystems RX7i series. After being inserted into the standard RX7i rack backplane and completing electrical docking and power supply wiring, the module automatically finishes hardware self-test, loop initialization, voltage calibration, load detection and fault clearing upon power-on, and enters the normal regulated power supply operating state.
The external 18~30VDC wide-range DC input voltage is preprocessed by input reverse connection prevention, multi-stage EMI filtering and surge voltage stabilization, then transmitted to the high-frequency inverter power unit for voltage conversion, and finally outputs standard regulated power of +5VDC, +12VDC and -12VDC through multiple independent voltage regulation loops. The 5V high-current main output supplies power to rack backplane CPUs, logic circuits and core I/O modules, while the ±12V auxiliary output supplies power to peripheral detection, communication and small actuating equipment. The high-precision voltage sampling loop feeds back output status in real time and dynamically corrects voltage regulation parameters to ensure constant voltage and controllable ripple under full-load conditions.
During operation, the built-in timing control unit strictly manages the graded logic of system power-on and power-off to avoid instantaneous current impact. Meanwhile, it monitors input voltage, output current, overall module temperature and load conditions in real time throughout the process, and identifies various abnormal faults through full-dimensional hardware protection mechanisms including overvoltage, undervoltage, overcurrent, overheating and short circuit. Under fault conditions, it instantly cuts off output, latches faults and lights alarm indicators to isolate faults and protect rear-end equipment. Under normal working conditions, it adaptively matches load changes and continuously outputs stable multi-channel purified regulated power, providing safe, stable and accurate power supply guarantee for the entire RX7i industrial control system and supporting 24/7 uninterrupted continuous equipment operation.
