Tips: Overvoltage protection of the voltage stabilizer

When the output voltage exceeds the voltage stabilizer protection value (the phase voltage protection value is adjusted to 250V±5V at the factory), the voltage stabilizer will automatically protect, reduce or cut the voltage output voltage of the stabilizer, and the over-voltage indicator light will be on, the user should immediately shut down to check the grid voltage or the voltage stabilizer. When the voltage stabilizer is working, if the output voltage is jitter, it may be capacitive or the inductive load is too heavy. The user can adjust the switch on the circuit board in the case to eliminate the jitter (please turn off the load when adjusting). If the shaking cannot be eliminated, it may be caused by too much internal resistance of the input grid line or serious distortion of the input waveform.

If the voltage stabilizer is under overvoltage protection after starting, please check whether the stabilizer is adjusted normally and whether the grid voltage is out of the range of the voltage stabilizer. Switch on the voltage stabilizer and turn on the electrical equipment after the output voltage is stable.

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.

A voltage stabilizer is a device that automatically adjusts the output voltage to stabilize it. ATO will show you how to test a voltage regulator.

ATO Responded

What type of remote control do you need? We can provide RS485 communication remote control or WIFI network remote control. How many units do you need?

Operating conditions of the regulator

Can you give us a quick update under which conditions the unit must be installed: Distance from the machine it drives? Distance from the machine it drives? Distance to walls? Temperature/humidity requirements?

ATO Responded

Please find our answer below:
1. We don't recommend you mount it on the ceiling since the stabilizer is too heavy.
2. The temperature range of our stabilizer is -15°C~+40°C.
