2. Technical Introduction
Unstable auxiliary power or sudden voltage sags can cause mission-critical Remote Terminal Units (RTUs) to reboot, resulting in temporary telemetry loss across vital power transmission nodes. Maintenance personnel managing substation grid automation require robust, high-reliability power infrastructure capable of seamlessly supporting parallel redundancy. The ABB 1KGT006600R0002 (560PSU01 R0002) slides directly into RTU560 subracks (such as the 560SFR02 or 560MPR03), converting high-voltage DC feeds into tightly regulated 5V and 24V rails while supporting active load sharing for redundant configurations.

4. Field Engineer’s Tech Notes
- Redundant Parallel Balancing: When configuring dual 560PSU01 units for redundant operation in high-availability subracks, ensure that both modules match exact rubric and firmware revisions. The units feature controlled load balancing, but mismatched versions can cause uneven thermal wear.
- Input Voltage Interruption Resilience: The module rides through short supply drops of up to 50 ms (at voltages >48 V DC). Verify that your station battery system’s upstream circuit breakers are sized appropriately to prevent nuisance tripping during minor auxiliary transients.
5. Adaptive QA & Testing Protocol
Our testing workflow for power supply units involves running each module on an automated electronic load bank simulating real-world RTU560 subrack draws. We verify regulation accuracy across both 5.1V and 24V output rails under step-load conditions, check ripple voltage parameters against strict factory thresholds, and test parallel load-sharing behavior. Full diagnostic test profiles and inspection certificates are available upon request.
6. Buyer’s FAQ
- Q: What warranty is included with this power supply unit?
A: All purchases include a standard 12-month replacement warranty covering structural and operational performance.
- Q: Are terminal blocks included with the module?
A: Yes, the unit ships with the necessary 3-pole pluggable screw terminal blocks (PKB type) for quick wiring of the DC input supply.
- Q: Is this part supplied as new surplus or refurbished?
A: Inventory status is precisely identified as New Surplus (NSFP) or factory-refurbished hardware; contact our sales team to verify current warehouse batch conditions.
