Tips: Notes when using SCR AC regulator modules.

When wiring, be careful not to confuse the live (L) and neutral (N) wires in main circuit. Grid voltage cannot be lower than the lower limit of load voltage, otherwise the SCR regulator module cannot operate normally.
Resistive load must not exceed 60% of the regulator module rated current. Inductive or capacitive load cannot exceed 40% of the rated current. Motor load must not exceed 20% of the rated current.
Overcurrent and short circuit are the main causes of permanent damage to the thyristor. Therefore, pay attention to the overcurrent protection for SCR voltage regulator module. Current protection can be performed using fast-acting fuses or air switches.
When using the SCR voltage regulator module, corresponding heat sink should be equipped. When the load radiation conditions are not good, compensation should be increased, and short-circuit loads are not allowed.
