The TOMZN TOVS-16Z is an intelligent voltage protective socket designed for US AC110V/120V standard outlets. It integrates over-voltage and under-voltage protection functionalities to safeguard electrical equipment.

2.1 Function Overview

When the voltage in the circuit is too high or too low, the equipment will automatically cut off the circuit to prevent damage to connected appliances. The over-voltage and under-voltage protection values are user-adjustable to suit local practical conditions.

2.2 Key Features

  • Automatic Power Off: Instantly powers off in case of over-voltage or under-voltage faults.
  • Automatic Restoration: Automatically restores connection after a time delay once the voltage returns to normal.
  • Transient Over-voltage Protection: Protects equipment from false operation due to transient voltage spikes.
  • Stability Protection: Disconnects the line during unstable voltage or sudden power changes caused by loose connections or other faults.
  • Self-Protection: The product itself is designed to withstand peak fault voltages without damage.

6. Maintenance

To ensure the longevity and proper functioning of your TOMZN TOVS-16Z Voltage Protective Socket, follow these maintenance guidelines:

  • Keep the device clean and free from dust and debris.
  • Do not expose the device to moisture or extreme temperatures.
  • Regularly check for any signs of damage to the casing or plug.
  • Always disconnect the device from the power source before cleaning or when not in use for extended periods.
  • Ensure adequate ventilation around the device during operation to prevent overheating.

7. Troubleshooting

The TOVS-16Z is designed for automatic protection. If an issue occurs, the device will typically display an error code and cut off power.

7.1 Common Indicators

  • 'HU' Code Displayed: Indicates an over-voltage protection event. The device has cut off power due to voltage exceeding the set over-voltage protection value. Power will be restored automatically after the voltage returns to normal and the recovery delay time has passed.
  • 'LU' Code Displayed: Indicates an under-voltage protection event. The device has cut off power due to voltage dropping below the set under-voltage protection value. Power will be restored automatically after the voltage returns to normal and the recovery delay time has passed.
  • No Power/No Display: Check the power source. Ensure the device is securely plugged into a functioning outlet. If the issue persists, the device may require professional inspection.

If the device repeatedly triggers protection or does not restore power as expected, verify your voltage settings and consult an electrical professional.

8. User Tips

  • Verify Voltage Compatibility: Upon receipt, double-check that the device's specifications match your local voltage (e.g., 110V/120V for US outlets) to avoid compatibility issues, especially if there are conflicting voltage ratings in documentation.
  • Basic Functionality: This device provides reliable basic over and under voltage protection. It is a straightforward and functional solution for safeguarding your appliances.
  • Confirm Settings: Before initial use, ensure the over-voltage and under-voltage protection values are set appropriately for your region and connected appliances.
