Product Performance

High-Reliability Power Supply: The four-fold protection mechanism has a response time ≤100μs, which can quickly cut off the output in abnormal scenarios such as voltage fluctuations and load short circuits. The Mean Time Between Failures (MTBF) is ≥100,000 hours, meeting the 7×24-hour continuous operation requirements of network equipment.
Flexible Redundancy Configuration: Supports 1+1 parallel redundancy. When two modules are connected in parallel, load current sharing can be automatically realized. When one module fails, the other module takes over the power supply immediately with a switching time ＜5ms, ensuring no business interruption risk.
Wide Environmental Adaptability: The operating temperature range of 0℃ to +40℃ and 3g vibration resistance are suitable for complex environments such as computer room air conditioning failures and cabinet vibrations, and can operate stably without additional temperature control or shock absorption devices.
Efficient Energy-Saving Feature: With conversion efficiency ≥80%, the annual power consumption is reduced by approximately 300 kWh compared with ordinary power supplies when operating at 625W full load; the power factor ≥0.9 reduces grid harmonic interference, meeting the energy efficiency standards of green data centers.
Convenient Maintenance Design: The hot-swap function supports live module replacement without turning off the equipment. Combined with LED status indicators, faults can be quickly located, reducing maintenance time to within 5 minutes.
