Outline
The EPM Energy-Saving Power Module Series is a series of energy-saving switching power modules with built-in
switching transformers, control ICs, control circuits and switching elements (FET).
Attaching the input noise filter, the input rectifier diode and the output smoothing capacitor externally enables the
easy creation of power switching with high-efficiency, low-standby power.
Features
・
Quasi-resonant operations for high efficiency.
・
Operations using both frequency reduction and bursts for generation of low-standby power.
・
Supports worldwide input and PFC output voltages (Vin: DC110V to 450V)
・
Reinforced insulation between Primary and Secondary (AC3000V guaranteed for one minute).
・
Resin filling is available to reduce audible noise.
・
Compliant with all required safety standards for information equipment, AV equipment, industrial equipment, and
home appliance equipment.
・
Various built-in protection functions (overcurrent, overvoltage and overheating protection).
