(Note: This write-up is an informative manual-style summary—not an official manufacturer document.)

Ensure all terminal screws are tightly fastened to prevent overheating. Power On: Switch on the main breaker and check the display. Troubleshooting & Tips

This confusion about the product’s identity is a good example of why a proper manual is so important. If you’re looking for documentation on a portable EV charger, this guide may not be for you. But if you want to understand how to install and use an electrical protection device to keep your home’s wiring safe—you’re in the right place.

The device includes built-in macro-actions executed directly from the home screen display mode:

Set the undervoltage threshold just below your normal minimum voltage—enough to detect a brownout or sag without nuisance tripping. tomzn tovpd160ec manual better

Press and hold the DOWN button for more than 12 seconds to restore all default settings. Installation and Safety Tomzn Voltage Protector

| Specification | Value | | :--- | :--- | | | 230V AC, 50/60Hz | | Current Range | Adjustable (1–63A typical, with some models supporting up to 80A or 100A) | | Overvoltage Trip Range | Adjustable (typically 230–300V, default 270V) | | Undervoltage Trip Range | Adjustable (typically 140–210V, default 170V) | | Trip Time Delay | Adjustable 0.1–30 seconds (default 0.5s) | | Recovery Delay | Adjustable 1–500 seconds | | Installation | Standard 35mm DIN rail | | Power Consumption | <2W | | Operating Temperature | -20°C to +55°C |

The TOMZN module functions as a smart safety relay monitor rather than a dedicated short-circuit magnetic trip mechanism. You must place a standard Miniature Circuit Breaker (MCB) upstream to shield the device from massive short-circuit currents. If you’re looking for documentation on a portable

Protects motors and compressors (like those in refrigerators) from burning out during brownouts.

Prevents damage from sudden voltage spikes.

Automatically restores power once conditions return to safe levels, following a customizable delay. Technical Specifications Default Value Adjustable Range Rated Voltage 230V AC (50/60Hz) 140V – 300V Max Loading Power 1A – 63A Over-Voltage Trip 230V – 300V (or OFF) Under-Voltage Trip 140V – 210V (or OFF) Power-On Delay 1s – 500s Action Time 0.1s – 30s Programming & Manual Operation

These specifications ensure reliable operation under normal household conditions. Press and hold the DOWN button for more

Press and hold the UP button for more than 12 seconds to view the last recorded fault reason (e.g., "Er1" for over-voltage).

Set the under-voltage shutdown limit (Default 170V).

Optimizing this 60A/63A dual-display digital guardian prevents catastrophic equipment failure from grid surges, brownouts, or overcurrent faults. Core Specifications Overview

Press and hold the M button for 3 seconds until the display flashes.

: Wire the downstream load (household distribution box or individual heavy appliances) to the bottom terminals marked L (Live) and N (Neutral).

: Tighten terminal screws thoroughly to minimize contact resistance, which causes localized heating under high current loads. Advanced Parameter Settings Matrix
