The new ZERO CROSS SCR GATE DRIVER NWZC-SCR, is a low cost SCR driver for driving back to back SCRs in resistive load applications. The driver board is zero cross fired and has on board MOV protection. It provides optically isolated 5V, 24V inputs that can easily be interfaced to temperature controllers and PLC Time Proportiong (PWM) outputs. The packaging is available in panel mountable or din rail mountable snap tracks.
SCRs requiring 200mA of gate current or less are a good fit for use with the ZERO CROSS SCR GATE DRIVER NWZC-SCR. Wiring of the Module is simple and requires no external power supply; the gate drive power is derived from the line supply of the SCRs.
