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‑current, over‑temperature, short‑circuit multi‑protection, power‑OK LED indication, heavy‑load RX3i rack power supply.
Application Scenarios Fully‑loaded RX3i main rack, medium‑large RX3i automation control cabinet, system with numerous high‑power‑consumption modules.
Performance Parameters Output voltage tolerance ±5% Thermal protection auto‑lock function Continuous heavy‑load industrial operation capability Shock & vibration:Comply with IEC 60068
Structural Characteristics Standard RX3i rack dedicated power‑slot module Front‑panel POWER‑OK LED indicator Front‑mount AC input terminal block Backplane gold‑finger high‑current power contact Internal high‑power switching power conversion circuit Mechanical locking latch
Working Principle AC input passes EMI filter, rectification and high‑power switching conversion, outputs stable 5VDC power for RX3i rack backplane bus. Real‑time monitoring circuit detects output current, voltage and internal temperature. When fault occurs, protection circuit cuts output and extinguishes power‑OK LED.
Installation Requirements Mount into RX3i main rack dedicated power slot. Complete reliable cabinet protective ground. Calculate total backplane power consumption of all modules, ensure not exceed rated 72W. AC input wiring meets current‑carrying specification. Disconnect AC power supply before module replacement, hot‑swap forbidden. Guarantee cabinet ventilation heat dissipation.
Usage Notes Backplane total load shall not exceed power supply rated capacity. Prevent AC input surge interference. Keep ventilation openings unobstructed. Observe POWER‑OK LED status periodically. On‑site disassembly is prohibited. Avoid heavy dust, corrosive gas and liquid splash environment.
