Power Adapter

Product description

This product is a DC output power adapter, the input part can automatically detect 260V - 100V alternating current, multi-channel output, output current up to 500mA, the feedback part of the use of the TL431/TL432 three terminal voltage regulator circuit, so the output voltage is high, the output voltage ripple characteristics。
