Description

Protection Functions

Temperature Protection: Mounted on the coil temperature sensor, when the temperature reaches 110, the voltage regulator automatic protection to cuts off the output.
Overload Protection: When the load power reaches 120%, the stabilizer automatically protects and cuts off the output.
Under Voltage Protection: When the output voltage is lower than 140V, the underpressure indicator light rises and the output is cut off.
Over Voltage Protection: When the output voltage is higher than 260V, the overpressure indicator light rises and the output is cut off.
Lightning Protection: Integrated protection system to prevent direct lightning or lightning electromagnetic pulse damage to the building itself or internal equipment.

Tips: How does a voltage stabilizer work?

A voltage stabilizer is a device that stabilizes 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 samples, compares, and amplifies the variation, then it drives the servo motor to rotate to change the position of the 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.
