Note 1: According to the voltage and current of load, choose a suitable varistor to protect the thyristor. A
resistor-capacitor circuit (RC circuit) is needed for inductance load or phase-shift trigger output.
Note 2: SCR power module is recommended. A power module includes two SCRs, is similar to the above dashed
square.
Note 3: K5 and K6 TRAIC trigger module only support 220～380VAC and 50Hz power.
