TNS 380V Voltage regulator

brief introduction

Low-power three-phase voltage stabilizers are electrical devices used to stabilize the voltage of three-phase AC power sources, suitable for various environments that require high stability of the power supply, such as factories and large shopping malls. They typically consist of control circuits and servo motors, which can automatically adjust the output voltage to maintain stability when there are changes in input voltage or load.

Technical Parameters

- **Input Voltage Range**: Generally, three-phase 260V-430V.

- **Output Voltage**: Typically three-phase 380V±3%.

- **Adjustment Time**: Less than 1 second (when the input voltage changes by 10%).

- **Efficiency**: Greater than or equal to 90%.

- **Ambient Temperature**: Usually operates within the range of -10°C to +40°C.

- **Relative Humidity**: Less than 90%.

- **Waveform Distortion**: No additional waveform distortion.

- **Frequency**: 50Hz or 60Hz.

- **Insulation Resistance**: Greater than 5MΩ.

Working Principle

The working principle of the three-phase voltage stabilizer is achieved through the internal three independent transformers and control circuits. The control circuit monitors the three-phase voltage and provides feedback control based on the set values. When there is a fluctuation in the input voltage, the control circuit adjusts the operation of the transformer to maintain the output voltage within the set stable range.

Application Fields

Low-power three-phase voltage stabilizers are widely used in home appliances, modern office equipment, educational systems, communication networks, monitoring systems, audio engineering, medical and health equipment, CNC machining equipment, and other equipment that requires a stable power supply.

 Maintenance and Operational Precautions

- Avoid violent vibrations, prevent the inflow of corrosive gases and liquids, prevent moisture, and place in a ventilated and dry place.

- Use a three-prong (grounded) socket to ensure good grounding.

- Regularly check the input and output wiring of the voltage stabilizer to prevent loosening or falling off.

- Keep the interior of the machine clean, and clean and maintain the coil contact surface in time.

- Pay attention to the wear of carbon brushes, and replace or adjust the pressure when necessary.

 Selection Suggestions

When selecting a three-phase voltage stabilizer, the type should be based on the rated power and load type of the electrical equipment. For special loads, such as large inductive or capacitive loads, the power of the selected stabilizer should be more than three times the power of the load.
