About the Product
The PC817C Optocoupler is a widely used electronic component designed for signal isolation and reliable communication in power supply circuits. Commonly found in ASIC miner power supplies, this optocoupler helps protect sensitive control circuits from voltage spikes, surges, and electrical noise.

With its high isolation voltage and fast response time, the PC817C ensures stable operation of mining PSUs by transmitting signals accurately while keeping high-voltage and low-voltage sections safely separated. This makes it an essential replacement part for repairing or maintaining Antminer, Whatsminer, and other ASIC miner power supplies.
