Power Modules

Tamura Power Modules are energy-saving switching power supply modules with a switching transformer, IC control, circuit control, and a built-in (FET) switching component. A high-efficiency and high-performance switching power supply with low standby power can easily be created with the Tamura Power Modules by attaching an external input noise filter, input rectifier diode, and output smoothing capacitor.
