2 kVA Single Phase Automatic Voltage Stabilizer for Home

Protection Functions

1. Delay Protection: Delay protection starting voltage stabilizer, waiting for 5 seconds to be able to work (in 5 seconds to prevent instaneous voltage impact on electrical applicances).
2. Temperature Protection: Mounted on the coil temperature sensor, when the temperature reached 110, the voltage regulator automatic protection to cut off the output.
3. Overload Protection: When the load power reaches 120%, the stabilizer automatically protects and cuts off the output.
4. Under Voltage Protection: When the output voltage is lower than 140V, the underpressure indicator light rises and the output is cut off.
5. Over Voltage Protection: When the output voltage is higher than 260V, the overpressure indicator light rises and the output is cut off.
6. Lightning Protection: Integrated protection system to prevent direct lightning or lightning electromagnetic pulse damage to the building itself or iternal equipment.

Tips: How does a voltage stabilizer work?

A voltage stabilizer is a device that stabilize the output voltage, it consists of a voltage regulation circuit, control circuit and servo motor. When the input voltage or load changes, the control circuit would sample, compare and amplify the variation, then it drives the servo motor to rotate to change the position of voltage regulator's carbon brush. By automatically controlling the coil's turns ratio, it ensures a stable output voltage.
As some electrical appliances contain coil packs, eddy current blocking the current would generate at the initial stage of power supply, the eddy current will weaken the instantaneous voltage when electrical appliances start, and thereof lead to a slow start-up, as well as strengthening the transient voltage generated after open circuit, which may cause sparks to damage circuits. So a voltage stabilizer is needed to protect the normal operation of the circuit.
