SCR gate driver BAP-1106

BAP-1106 SCR Gate Driver Board for Single Large Area Thyristor Devices' The AP-1106 provides a complete, field-tested turnkey solution to drive a single large area thyristor device. This driver accepts a logic level control input and provides an isolated DC drive current into the SCR gate, able to hard drive up to 100mm size devices. The output gate drive signal is applied thru a pulse forming network that creates a fast rising leading edge current pulse (typically 5A/µSec) into the SCR gate, maximizing the device di/dt capability and insuring proper SCR turn on. The on board 115VAC power supply provides all needed power to drive the SCR and provides transformer isolation between the AC input and the SCR being driven. A high speed optocoupler provides isolation between the customer supplied logic level signal and the SCR. LED indicators display POWER ON and SCR ON status. The small footprint PCB assembly measures only 3.0” X 5.0”.
