560PSU02 Power Supply Unit: Reliable DC Power for RTU560 Systems

Key Technical Specifications

• Brand & Model: ABB 560PSU02 (ordering code 560PSU02 R0001 / 1KGT011900R0001).
• Input Voltage Range: 48...220 V DC with tolerance -20% to +15%.
• Outputs: U1 = 5.1 VDC (15A max), U2 = 24 VDC (0.4A max). Total power 85W.
• Efficiency: 74% @ 48...110 VDC. Short-circuit proof and over-voltage protected.
• Redundant Operation: Two 560PSU02 units can run in parallel. They share load and support full load if one fails.
• Voltage Interruption Tolerance: Withstands ≤50 ms input interruption (0% UN).
• Operating Temperature: 0°C to +70°C (nominal range). Derating -2.5%/Kelvin above 50°C.
• Relative Humidity: 5% to 95% non-condensing per EN 60068-2-30.

Frequently Asked Questions (FAQ)

• Q: Can I use a single 560PSU02 to power a fully loaded subrack?
  A: Yes. One 560PSU02 provides 85W total output, enough for up to 8 CMUs.
• Q: How do I set up redundant power with two 560PSU02 units?
  A: Connect both units in parallel mode. Use same type and rubric. The system monitors load balancing automatically.
• Q: What happens during a short voltage interruption?
  A: The 560PSU02 tolerates input interruptions up to 50 ms without output dropout (Class S1 per IEC 60870-4).
• Q: Does the unit require forced cooling?
  A: No. Natural convection provides sufficient cooling within 0-70°C ambient range.
• Q: What is the residual ripple on outputs?
  A: U1 ≤30 mVss, U2 ≤80 mVss – clean power for sensitive RTU560 electronics.
