Variac / Dimmer Type LT Automatic Voltage Stabilizers are ideal for low rating LT applications. The supply is generally recommended for up to 200 kVA, but it can be customized to 1000 kVA if necessary. Despite the differences in construction between a Variac / Dimmer Type Servo Voltage Stabilizer and a Rolling Contact Type Stabilizer, the functioning is nearly identical. Most appropriate for indoor installation with low capacity, unbalanced supply, and unbalanced loads. These servo stabilizers are made with copper wire for winding, CRNGO (Cold Rolled Non Grain Oriented) Lamination, and a carbon brush to carry current over the regulating coils. With a correction rate of up to 25 Volts per second.
