The ac outputs incorporate Crydom's back-to-back SCR technology while the dc outputs utilise high-efficiency FETs, both technologies offering low on-state power dissipation and high surge current ratings - ideal for applications such as small motors, solenoids, heaters and lamps. Optically isolated control inputs include 3 to 15Vdc, 18 to 32Vdc, 48 to 72Vdc, 18 to 36Vdc and 90 to 140Vdc.
