Core Features & Technical Advantages

Redundant Operation Architecture
Supports N+1 redundancy configuration with automatic load sharing and failover switching. When paired with a second 560PSR00 unit, the system maintains full output capacity even during single-unit failure, eliminating downtime in critical SCADA applications and extending maintenance windows.

Dual-Output Voltage Rails
Simultaneously provides regulated 5VDC (for logic circuits and communication modules) and 24VDC (for I/O interfaces and field devices) from a single compact unit. Total output power of 44.3W supports full RTU560 configurations including expansion modules and communication cards.

Wide Input Voltage Range
Accepts 24-60VDC input with active power factor correction, compatible with standard substation battery systems (48VDC nominal) and industrial DC bus architectures. Built-in input protection against reverse polarity, overvoltage transients, and surge events per IEC 61000-4 standards.

Industrial Temperature Performance
Operates reliably across -25°C to +70°C ambient range without derating, suitable for outdoor kiosks, unheated enclosures, and high-temperature equipment rooms. Conformal coating and sealed construction provide protection against humidity, dust, and corrosive atmospheres.

Comprehensive Protection Functions
Integrated safeguards include output overcurrent limiting, thermal shutdown, input undervoltage lockout, and short-circuit protection. LED status indicators provide real-time diagnostics for input power, output status, and fault conditions, reducing troubleshooting time during commissioning and maintenance.

Selection Considerations
When configuring your power supply system, evaluate: total load current for 5V and 24V rails (sum of RTU560 base unit + expansion modules + communication cards), station battery voltage (24V, 48V, or 60V systems), ambient temperature extremes at installation site, and redundancy requirements (single or dual PSU configuration). For loads exceeding 44W or custom voltage requirements, consult our engineering team for alternative ABB power supply models or parallel operation schemes.

Redundancy Configuration & System Integration

N+1 Redundant Setup
Install two 560PSR00 units on the same DIN rail with outputs connected via integrated ORing diodes. Each unit operates at 50% load during normal conditions; upon failure of one unit, the remaining PSU automatically assumes 100% load without interruption. This configuration is recommended for critical substations, unmanned sites, and applications where maintenance access is limited.

Load Sharing & Derating
In redundant mode, both units share the load equally, reducing thermal stress and extending service life. At 70°C ambient, each PSU can deliver full rated output; consult derating curves in the technical manual for operation above 70°C or at high altitudes (>2000m).

Wiring & Installation
Connect station battery (+/-) to input terminals with appropriate fusing (recommended: 5A fast-blow fuse on positive rail). Output terminals provide screw-type connections for 5V and 24V distribution to RTU560 backplane. Maintain minimum 10mm spacing between adjacent units for adequate convection cooling. Refer to ABB installation manual 1MRK511407-UEN for detailed wiring diagrams and grounding requirements.

Frequently Asked Questions (FAQ)

Q: Can the ABB 560PSR00 power supply operate with non-ABB RTU systems?
A: Yes, while optimized for RTU560 platforms, the 560PSR00 provides standard 5VDC and 24VDC outputs compatible with any industrial control system requiring these voltage rails. Verify total load current does not exceed 5A (5V rail) and 1A (24V rail) combined within the 44.3W power budget.

Q: How many 560PSR00 units are required for a fully redundant RTU560 configuration?
A: Two units are required for N+1 redundancy. Each PSU can independently power a complete RTU560 system; in dual configuration, they operate in load-sharing mode with automatic failover. For systems with multiple expansion racks or high I/O density, calculate total power consumption and consult ABB's RTU560 system planning guide.

Q: What is the expected service life and MTBF of the 560PSR00?
A: Under typical substation conditions (25°C ambient, 50% load), the 560PSR00 achieves MTBF >200,000 hours (>22 years) based on MIL-HDBK-217F reliability prediction. Electrolytic capacitors are rated for 10+ years at maximum operating temperature; preventive replacement is recommended during scheduled substation outages.

Q: Does the power supply require forced-air cooling or heat sinking?
A: No external cooling is required. The unit relies on natural convection cooling and is designed for DIN-rail mounting with minimum 10mm spacing from adjacent devices. Ensure enclosure ventilation meets ABB's thermal management guidelines; for installations in sealed outdoor cabinets, verify internal temperature does not exceed 70°C ambient.

Q: Can I monitor the power supply status remotely via RTU560 communication protocols?
A: The 560PSR00 provides local LED status indication (input OK, output OK, fault). For remote monitoring, connect the fault relay contact (if equipped on your model variant) to RTU560 digital inputs, enabling SCADA alarm integration via IEC 60870-5-104, DNP3, or Modbus protocols supported by the RTU platform.

Q: What protection is provided against lightning and electrical transients in substation environments?
A: The 560PSR00 incorporates input surge protection rated for IEC 61000-4-5 Level 4 (4kV common mode, 2kV differential mode) and fast-acting input filtering. For installations in high-exposure substations, supplement with external DC surge arresters on the battery bus and follow IEEE 1613 grounding practices to minimize ground potential rise effects.
