Alias name SSR-VA series ingle phase resistance to AC solid state voltage regulator
1. Special general circuit design for large current, high quality circuit board.
2. Use copper terminals for big current, increase the safety of connection and use.
3. Use pure aluminium base plate, with better performance and long life.
4. Hign-end flame-retardant PV plastic, thermostability can up to 70-80 degrees.
Note 1. Model selection method: calculate the load current, according to load type, multiply the balance factor.
Resistive load: balance factor is 2 times, such as incandescent lamp, resistance wire, oven, heating rod.
Inductive load: balance factor is 7 times, such as: transformer, coil, fan motor, pump motor.
Example: 220V 3KW resistive load. 3KW/220V*2=27.3, select 40A specification.

2. To use product long and safely, please install the product with corresponding heat sink and fan.
