Functional Features Wide‑range AC input, high output power, optimized thermal design, multi‑level protection, power‑OK LED indication, heavy‑load rack power feeding.
Application Scenarios Fully‑loaded main rack, spare replacement for IC693PWR330, medium‑large Series 90‑30 industrial control cabinet.
Performance Parameters Output voltage tolerance ±5% Improved high‑temperature heavy‑load stability Multi‑fault protection lock‑off Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard Series 90‑30 rack power‑slot module Front‑panel POWER‑OK LED indicator Front AC input terminal block Backplane gold‑finger high‑current power contact Internal optimized thermal‑layout switching circuit Mechanical locking latch
Working Principle AC input completes filtering, rectification and power conversion, outputs stable 5VDC power for rack backplane bus. Optimized thermal components reduce internal temperature rise under full load. Monitoring circuit triggers protection on over‑current, short‑circuit or over‑temperature faults.
Installation Requirements Mount into dedicated power slot of Series 90‑30 main rack. Complete reliable cabinet protective ground. Total backplane load power shall not exceed rated output. AC input wiring follows current specification. Cut off AC power before module replacement, hot‑swap not allowed. Keep cabinet good ventilation.
Usage Notes Strictly control total power consumption of rack modules. Avoid AC input surge interference. Ensure ventilation path is not blocked. Regularly check power‑OK LED status. On‑site disassembly is forbidden. Keep away from dust accumulation, corrosive gas and liquid splash.
