    Protection Functions

    1. Temperature Protection: Mounted on the coil temperature sensor, when the temperature reached 110, the voltage regulator automatic protection to cut off the output.
    2. Overload Protection: When the load power reaches 120%, the stabilizer automatically protects and cuts off the output.
    3. Under Voltage Protection: When the output voltage is lower than 140V, the underpressure indicator light rises and the output is cut off.
    4. Over Voltage Protection: When the output voltage is higher than 260V, the overpressure indicator light rises and the output is cut off.
    5. 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.

    In this video ATO uses a voltage regulator and multimeter to test the output voltage of the 3 kva voltage stabilizer which has 140V to 270V AC input, 220V AC output. After testing, we may see that the output voltage is within 220V ± 6%, which is in line with the standard.

    Do you have a 300kVA voltage stabilizer available?
    Dear Sameh, yes, we are attempting to solve a voltage imbalance of up to six percent at the supply to our chiller. We have monitored the phase-to-phase supply voltages and phase currents to the chiller. There is a very large discrepancy between one of the phase currents with respect to the other two phase currents: 475A vs 270A.
    We are now checking every wiring connection starting at the chiller and working back to the utility transformer.
    In anticipation that we may still need a product such as your voltage stabilizer, do you have any of the 300kVA units available now?

    ATO Responded
    Yes, our voltage stabilizer 3-phase input voltage will be balanced although its output voltage is unbalanced by approx 6%. We can customize the voltage stabilizer to adjust the voltage separately, which means that the output three-phase voltage can be adjusted independently.
    But for 475A current, 480V voltage, recommended voltage stabilizer capacity should be 475A * 480V * 1.732 * 1.5 times = 600kVA, and the 300kVA unit will not be sufficient to drive 2 units of 150A chillers.
    Worth buying
    This 2 kVA Single Phase Automatic Voltage Stabilizer works well. The output voltage is very stable and safe, well packed and quickly delivered.  I will definitely buy it again.
