Performance Parameters Power conversion efficiency is high; Output voltage ripple amplitude low; Protection action trigger quickly; Output voltage stability under input fluctuation; Long continuous operating life.
Material Composition Metal housing; High frequency transformer; Electrolytic and ceramic capacitor; Power semiconductor switching device; Aluminum heat sink; Glass fiber PCB control board; Screw terminals; LED indicator lights.
Structural Features Plug-in rack module design; Metal casing with ventilation hole for heat dissipation; Front panel LED indicator and power status relay terminal; Rear connector connects rack backplane; Internal heat sink tightly bonded with power devices.
Working Principle AC input passes EMI filter and rectifier circuit, converted to DC bus voltage. High frequency switching circuit converts bus voltage to stable 24V DC output. Output voltage and current are sampled continuously. Once overvoltage, overcurrent or overheat detected, control circuit cuts off power output. Power good relay contact changes state to inform host system power abnormality.
Installation Requirements Insert module into designated rack slot and lock connector; Input AC wiring must match voltage rating; Rack cabinet reliable protective grounding; Keep ventilation air flow through module cooling holes.
Precautions for Use Do not touch internal power components after power off before capacitor discharge; Keep ventilation holes free from dust accumulation; Do not operate with output short circuit continuously; Confirm load total current does not exceed module rated output; Replace module when power good alarm appears.
