Power transformers Commercial power transformers, transformer-type AC adapters, switching power transformers, smoothing choke coils We offer various power-peripheral parts such as commercial power transformers, switching power transformers, smoothing choke coils. Our transformer-type AC adapters with low power consumption during stand-by mode History of the Business Our power supply business started and grew with the appearance of power transistors. We have entered into the domestic market by developing transistor-type stationary power supply and then switching-type stabilizing power supply. We are developing and manufacturing AC adapters for PC for volume production, and industrial use power supplies for such as power controller and large transmitter, as well as compact power supply with high efficiency for such as artificial satellite and rocket. We also have long experience of development and production of electronic parts such as transformers and filters. Especially for governmental agencies, we have supplied with high quality and reliability products which comply with MIL or NDS standard. Amid the energy saving being more expected, we will continue to supply our products which are valuable for our customers.
