1. Introduction
The TAXNELE TVPS1-63P is a versatile 3-in-1 Din Rail Voltage Protector designed to safeguard electrical equipment from damage caused by overvoltage, undervoltage, and overcurrent conditions. This device automatically cuts off the power supply when abnormal conditions are detected and restores it once the line voltage returns to normal operating parameters. It also functions as a voltmeter, ammeter, and energy meter, providing real-time monitoring of your electrical system.
Key Features:
- Automatic Protection: Instantaneous power cut-off during overvoltage, undervoltage, or overcurrent events.
- Automatic Reconnection: Power supply automatically restores when conditions normalize.
- Adjustable Parameters: Overvoltage, undervoltage, overcurrent protection values, and reconnection delay time are fully adjustable.
- Real-time Monitoring: Integrated voltmeter, ammeter, and energy meter (kWh) for comprehensive electrical monitoring.
- Memory Function: Retains kWh, overvoltage, undervoltage, and overcurrent values even after power loss.
- Overcurrent Lock: If overcurrent events exceed a set number of times (1-20 adjustable), the protector locks, requiring manual reset to prevent frequent cycling and potential equipment damage.

5. Installation
Proper installation is crucial for the safe and effective operation of the voltage protector.
5.1 DIN Rail Mounting
The TVPS1-63P is designed for standard 35mm DIN rail installation.
- Ensure the DIN rail is securely mounted within your electrical panel.
- Align the protector with the DIN rail and press firmly until it clicks into place.
- Verify that the device is stable and does not wobble.

5.2 Wiring Instructions
Connect the device according to the wiring diagram provided. Always ensure power is OFF before wiring.
- Connect the incoming neutral (N) and live (L) wires to the 'IN' terminals at the top of the protector.
- Connect the outgoing neutral (N) and live (L) wires to the 'OUT' terminals at the bottom of the protector, leading to your protected load.
- Ensure all connections are tight and secure to prevent loose contacts and overheating.

It shows the protector connected in series between an incoming power source (left circuit breaker) and an outgoing load (right circuit breaker), with clear red and blue lines indicating live and neutral connections respectively.
6. Setup and Configuration
The protector allows for adjustment of various parameters to suit your specific needs.
6.1 Entering Settings Mode
- Press and hold the SET button for more than 3 seconds to enter the setting state.
- The display will show the first adjustable parameter.
6.2 Adjusting Parameters
- Use the UP and DOWN arrow buttons to change the value of the currently displayed parameter.
- Press the SET button briefly to cycle through the different adjustable parameters:
- Under Voltage Protection (140V-210V, Default: 170V)

9. Troubleshooting
Refer to the following common issues and solutions before contacting support.
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device not powering on | No input power; faulty wiring; device malfunction. | Check main power supply. Verify wiring connections. If power is present and wiring is correct, the device may be faulty. |
| Power cut-off, but conditions appear normal | Protection parameters set too sensitively; temporary voltage/current fluctuation. | Review and adjust overvoltage, undervoltage, or overcurrent settings. Increase reconnection delay time if frequent nuisance trips occur. |
| Device locks and does not restore power automatically | Overcurrent lock feature activated (exceeded set number of overcurrent events). | Manually press the SET button to unlock and restore power. Investigate the cause of frequent overcurrents in your system. |
| Incorrect voltage/current readings | Calibration issue; external interference. | While the device has a correction feature, if persistent inaccuracies occur, consult a qualified electrician or contact support. |
