ABB 1KGT011900R0001 560PSU02 Power Supply Unit

Technical Specifications Input Voltage Range: 48 VDC to 220 VDC Output 1: 5.0‑5.3 VDC, maximum output current 15 A Output 2: 22.4‑26.3 VDC, maximum output current 0.4 A Total Continuous Output Power: 85 W Residual Ripple: ≤30 mVss for 5 V channel, ≤80 mVss for 24 V channel Galvanic Isolation: complete isolation between input side and output side Internal Fuse: 4 A time‑delay T‑type fuse Hold‑up Time: minimum 50 ms under full load Operating Temperature: -25 ℃ to +70 ℃ Mechanical Form: 3HE Eurocard standard size Backplane Connector: 48‑pole DIN 41612 type‑F connector Input Terminal: 3‑pole pluggable screw terminal block

Functional Features Dual independent DC output channels for rack internal modules. Built‑in reverse input voltage protection circuit. Short‑circuit and over‑current automatic protection function. Input‑output galvanic isolation suppresses ground loop interference. Sufficient voltage hold‑up capacity for brief power interruption. Standard Eurocard plug‑in structure fits RTU560 rack installation.

Application Scenarios Power supply for RTU560 series remote terminal unit sub‑racks in electric power substations. Power feeding for 560MPR03 and 560SFR02 sub‑rack hardware assemblies. Automation control cabinet power supply for utility power grid monitoring sites. Remote power station unattended RTU system power distribution.

Performance Parameters Conversion efficiency reaches 74% under rated input condition. Output voltage deviation keeps within tight tolerance under full‑load and half‑load condition. Fast trigger response for short‑circuit fault protection. Stable output performance under wide input voltage fluctuation.

Material Composition Industrial multilayer printed circuit board. Metal shielding housing shell. High‑capacity electrolytic capacitors and power switching devices. Flame‑retardant plastic connector components.

Structural Features Standard 3HE Eurocard plug‑in board structure. Back‑end 48‑pin gold‑plated backplane connector. Front‑side pluggable screw terminal for power input wiring. Metal enclosure provides electromagnetic shielding effect.

Working Principle DC input voltage passes filter circuit and switching conversion circuit, converted into two groups of stable low‑voltage DC. Internal monitoring circuit detects output voltage, current and fault state. Galvanic isolation barrier separates primary input circuit and secondary output circuit to block interference transmission between power source and system backplane.

Installation Requirements Insert module into dedicated slot of RTU560 system rack. Ensure complete engagement of backplane connector. Complete input power wiring via front‑end plug‑in terminal block. Reserve surrounding space for natural convection heat dissipation.

Usage Notes External 10 A circuit breaker shall be configured for input power loop. Do not replace internal fuse with non‑specified specification. Confirm input voltage range matches module rating before power‑on. Keep distance from high‑voltage signal wiring inside cabinet.
