Key Technical Parameters Electrical Specifications DC Input Voltage: +24 V nominal (operational range ~21 V to 28.4 V DC). Input Shutdown Thresholds: Low-Voltage Shutdown ~19 V (restart ~21 V DC). High-Voltage Shutdown ~30.4 V (restart ~28.4 V DC). Maximum Input Current: ~70 A (at nominal input). DC Output Voltage: -48 V DC (typical adjustable range ~-52 V to -56 V DC). Output Power: Approximately 1200 W. Typical Efficiency: ~89 %. Environmental Operating Temperature Range: Up to +75 °C (wide industrial / telecom operating range). Cooling: Air-cooled design for continuous operation in power systems. Control & Monitoring Status Indication: Green LED — Normal operation Yellow LED — Alarm Red LED — Failure Flashing Red LED — Fan failure Alarm Output: Dry relay contact for remote alarm integration. Typical Functional Highlights Efficient +24 V to -48 V DC conversion — ideal for legacy telecom loads powered from +24 V plants. High power density for space-constrained rack or embedded installations. Hot-pluggable design (in many system configurations) for on-line serviceability. Robust performance across wide temperature and varied load conditions.
