Product Performance

Efficient and Energy-Saving Operation: 92% high conversion efficiency reduces energy loss. When operating at 70W full load, the annual power consumption is reduced by approximately 180 kWh compared to ordinary power modules (85% efficiency), adapting to industrial energy-saving transformation scenarios.
Stable Output in Wide Temperature Range: No derating operation in the full temperature range of -20℃ to +70℃, no start-up delay in low-temperature environment, and output voltage drift ≤1% during 72-hour continuous operation at high temperature (+70℃), adapting to severe cold workshops and high-temperature equipment cabins.
Strong Anti-Interference Ability: Built-in EMC filter circuit and metal shielding housing, in the environment of inverter clusters and high-frequency signal equipment, the output ripple is stably ≤50mV, ensuring the normal operation of precision equipment such as PLCs and sensors.
Fast Fault Protection: Overvoltage, overcurrent and overheating protection response time ≤100μs, which can cut off the output instantly when the circuit is abnormal, avoiding damage to downstream equipment; automatic power recovery after fault elimination, no manual restart required.
Flexible Integration and Adaptation: Compact size (120×60×30mm) saves control cabinet space, supporting side-by-side installation of multiple modules; Phoenix terminal design facilitates quick wiring, with wiring efficiency increased by 50% compared to traditional terminals.
