2. Product Overview

The TOMZN TOVPD1-60-EC is an intelligent comprehensive protector designed for home electrical systems. It automatically monitors and protects against over-voltage, under-voltage, and over-current conditions. When the voltage or current in the circuit exceeds set limits, the equipment will automatically cut off the circuit to prevent damage to appliances and ensure safety. It features real-time digital display of voltage and current, and allows for adjustable protection parameters and automatic recovery.

Key Functions:

  • Over-voltage protection
  • Under-voltage protection
  • Over-current protection
  • Automatic recovery
  • Real-time Voltage display (voltage measurement)
  • Real-time Current display (current measurement)
  • Adjustable Voltage calibration (A13)
  • Restore factory settings (press down button for >12s)
  • Fault inquiry (press UP button for >6s)

Wiring Diagram:

When connecting the power line input through the L (Live) and N (Neutral) terminals, ensure to screw down firmly to penetrate the insulating layer of the power lines for a secure connection.

Wiring diagram showing the connection of the TOMZN protector between a circuit breaker (TOB1L-63) and another circuit breaker (TOB1-63). The input (IN) terminals are connected to the main power supply (L and N), and the output (OUT) terminals are connected to the load. Red wires indicate Live (L) and blue wires indicate Neutral (N).

6. Maintenance

  • Regularly inspect the device for any signs of physical damage or loose connections.
  • Keep the device clean and free from dust and debris to ensure proper ventilation and operation.
  • Ensure the installation environment is dry and well-ventilated, away from direct sunlight or extreme temperatures.
  • If the device is not in use for extended periods, disconnect it from the power supply and store it in a safe, dry place.

7. Troubleshooting

  • Device not powering on: Check the input voltage and ensure it is within the AC 140-300V range. Verify wiring connections.
  • Device trips frequently: Review the set over-voltage, under-voltage, and over-current protection values (A2, A6, A10). Ensure they are appropriate for your electrical load and supply.
  • Device does not recover automatically: Check the recovery delay times (A4, A8, A11) and ensure automatic recovery is enabled (if applicable, based on settings).
  • Incorrect voltage/current readings: Perform voltage and current calibration (A13, A15) if you suspect inaccuracies.
  • Unknown fault: Use the fault inquiry function (press UP key for >6s) to check for the latest fault code. Consult a professional if the issue persists.
  • To restore factory settings: If you encounter persistent issues or wish to revert to default parameters, press the SET button for more than 12 seconds.
