Power Module
Unique Sleep Mode
In stanby state, the enery generated by power module is part of the operating cost of chargers. DCM series power modules control the standby power within 8W, and the power of sleep mode(patented technology) is even less than 2W, greatly reducing the operating cost.
Intelligent Parallel Mode
In stanby state, the enery generated by power module is part of the operating cost of chargers. DCM series power modules control the standby power within 8W, and the power of sleep mode(patented technology) is even less than 2W, greatly reducing the operating cost.
High Conversion Efficiency
In stanby state, the enery generated by power module is part of the operating cost of chargers. DCM series power modules control the standby power within 8W, and the power of sleep mode(patented technology) is even less than 2W, greatly reducing the operating cost.
Overall Temperature Monitoring
Temperature monitoring on up to 8 points such as ambient temerature, DSP control circuit, power devices, magnetic devices and so on, which greatly ensure the stable and reliable operation of power module
Three-proofing design
Use proprietary structures to stengthen the protection of semiconductor devices. Automatic spraying process of three-proofing coating, thickening the sealing of core parts, and so on measures to intensify the denfenses of moisture, salt spray and fungus.
MTBF > 100,000 Hours
DSP digital control to reduce analog devices, professional heat flow design to reduce temperature rise, long-life electrolytic capacitors and international brand components to ensure the quality of power modules.
Wide Input Voltage Range
DCM series power modules have input voltage from 260Vac to 470Vac, compatible with EV models of different voltage levels, supporting the charging of both electric buses and electric sedans.
Wide Working Temperature Range
With working temperature from -30°C ~ to 75°C(Derating above 55°C), DCM series power module work safely and reliably in extreme cold and hot environment.
DCM series power module have conventional protections such as input overvoltage protection, input undervoltage protection, output overvoltage protection, output current limit protection, output short circuit protection, over temperature protection, and low temperature protection. It also adopts PFC wave-by-wave current limit protection and LLC resonant cavity over current protection (Patented technology), providing reliable technical support for the operation of power modules.
