Technical Specifications Input Voltage:120/240VAC auto‑range Output:5VDC, 72W Backplane Supply Current:14.4A @5VDC Isolation Voltage:1500V RMS Operating Temperature:0℃～+60℃ Storage Temperature:-40℃～+85℃ Relative Humidity:5%-95%, non‑condensing Certifications:CE, UL, cUL
Functional Features Auto‑range AC input, high output power, over‑temperature, over‑current, short‑circuit multi‑protection, power‑OK LED indication, heavy‑load rack power supply.
Application Scenarios Fully‑loaded main rack, complex medium‑size Series 90‑30 automation system, control cabinet with numerous high‑power modules.
Performance Parameters Output voltage accuracy ±5% Thermal overload protection function Long‑term continuous heavy‑load operation capability Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard Series 90‑30 rack dedicated power‑slot module Front‑panel POWER‑OK status LED Front‑mount AC input terminal block Backplane gold‑finger high‑current power contact Internal high‑power switching power circuit Mechanical locking latch
Working Principle AC input passes EMI filter, rectification and high‑power switching conversion, generates stable 5VDC power to supply rack backplane bus. Real‑time monitoring circuit detects current, voltage and internal temperature. Fault triggers protection action and cuts output.
Installation Requirements Install into Series 90‑30 main rack power slot. Reliable cabinet protective grounding. Calculate total backplane power consumption and ensure not exceed rated 72W. AC input wiring matches current requirement. Disconnect AC power supply before replacing module, hot‑swap forbidden. Guarantee cabinet ventilation and heat dissipation.
Usage Notes Over‑load of backplane total power is prohibited. Prevent AC input surge impact. Keep ventilation openings unblocked. Inspect POWER‑OK LED status periodically. Do not disassemble module on‑site. Avoid heavy dust, corrosive gas and liquid splash environment.
