Core Functional Characteristics
Redundant Parallel Operation
The rack can be dual 560PSU02 connected for redundancy; in case of a single unit failure, the other unit will carry the full load, providing high reliability for power SCADA standard configuration.
Status Indicator Lights
Independent LEDs indicate the normal operation of 5V and 24V outputs, facilitating intuitive judgment of power failures.
Heat Dissipation Method
Natural convection cooling, no forced fan, reducing the rate of on-site failures.
Load Capacity
A single unit can support an entire rack with full configuration of 8 CMU communication units.
Installation Form
Standard RTU560 rack slot hot-swappable module, cabinet IP20 protection.
Environment and Certification
Operating Temperature: -25℃ ~ +70℃; Storage – 40℃ ~ +85℃
Humidity: 5% – 95% without condensation
Certification: CE, UL, IEC 61810 Power Automation Standard
Size: Approximately 258×225×40mm, Net Weight ≈ 0.67kg
Differentiation of the Same Series Power Supply
560PSU01: Input 110 – 220 VDC, Supports at most 4 CMU, Power is smaller
560PSU02 1KGT011900R0001: Wide Input 48 – 220 VDC, 85W, Full load 8 CMU, Mainstream large-capacity rack power supply
Typical Application Scenarios
