SCR Power Module
1: According to the voltage and current of load, choose suitable varistor to prevent the thyristor. Capacitor resistor
absorber is needed for inductance load or phase-shift trigger output.
2: SCR power module is recommended. A power module includes two SCRs, is similar to the above dashed square.
3: K5 phase-shift trigger module is only suitable for 200
～
240VAC / 50Hz power. K6 phase-shift trigger module is only for
380VAC below non-standard environment.
