Precautions for regulated power supply

Jun 09, 2019

1. In order to prevent magnetic leakage interference, the distance between the voltage stabilizer and the equipment used should not be less than 2 meters. Various magnetic records, disks, cards, etc. should be kept 2 meters away from the machine to prevent accidental magnetization.

2. The voltage stabilizer generally includes input terminals (A, B, C), output terminals (a, b, c, n), shielding, and iron core shell grounding terminals. These terminals have been correctly connected in the voltage stabilization system.

3. If the unbalance of the load exceeds 20%, connect a resistive load in parallel with one phase of the light load to balance it. Similarly, if the unbalance of the line voltage at the input terminal is greater than 10%, it will also affect the voltage stabilization performance of the machine , at this time, a single-phase voltage regulator should also be installed from the input end to make the line voltage of the input end basically balanced. The balance of the input voltage and the load should not exceed the above range, and the output line voltage unbalance should be less than or equal to 5%.

4. When there is a short circuit in the load equipment, the user needs to shut down the machine to check, remove the short circuit fault, and then turn it on again.

5. When the continuous working time is long, the machine has a certain temperature rise, and the indicated value will drop slightly, slightly lower than the actual voltage value.

6. It should be placed in a well-ventilated location. If the ventilation conditions are poor, please install a ventilation fan indoors. [1]
