Installation Environment and Precautions for Regulated Power Supply

Installation environment of regulated power supply

The stabilized voltage power supply should be used indoors in a ventilated and dry place. The usage conditions are strict. The installation site should be free of gases, steam, chemical deposits, dust, greasy dirt and other explosive and corrosive media that seriously affect the insulation performance of the voltage stabilizer. There should be no serious vibration or bumps.

When the stabilized power supply arrives at the installation site, it should be handled with care. The voltage stabilizer should always be in a vertical upward state and must not withstand wind, snow, ice, or hail.

Before debugging and installing the stabilized power supply, you must first check that all components of the equipment are intact and the fixings should be firm and reliable. Confirm again whether the voltage of the usage site is consistent with the voltage of the voltage stabilizer. This equipment is a three-phase four-wire system with split-phase regulation. In this way, the system's neutral line (neutral line) connection has higher reliability requirements, and the contact resistance of the neutral line (neutral line) connection should be reduced as much as possible. This equipment must be well connected to the earth, and the ground wire cannot be used together with repeated ground wires of the power system (neutral wire and phase edge with the ground wire) to ensure safety and improve anti-interference performance.

Precautions for use

1. To prevent magnetic leakage interference, the distance between the voltage regulator 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 core shell grounding terminals. These terminals have been correctly connected in the voltage stabilizing system.

3. If the load unbalance exceeds 20%, connect a resistive load in parallel to one phase of the light load to balance it. Similarly, if the unbalance of the line voltage at the input end exceeds 10%, it will also affect the voltage stabilization performance of the machine. , at this time, a single-phase voltage regulator should also be installed at the input end to ensure that the line voltage at the input end is basically balanced. The balance between the input voltage and load does not exceed the above range, and the output line voltage imbalance is ≤5%.

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

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

6. It should be placed in a location with good ventilation. If the ventilation conditions are poor, please install a ventilation fan indoors.
