TXOV3 overvoltage and undervoltage protector is an intelligent adjustable voltage protector. integrating overvoltage protection, undervoltage protection and overcurrent protection. Applicable to single-phase AC voltage 110V~240V, rated working frequency 50/60Hz, Maximum working current 63A. In case of over-voltage fault, under-voltage fault and over-current fault in the Live wire , this product can instantly cut off the power supply and protect the electrical equipment from burning. When the line returns to normal, the voltage protector can automatically reconnect the line. The overvoltage value, undervoltage value, overcurrent value and protection time of the product can be adjusted. It is mainly used for overvoltage/undervoltage protection of incoming lines of residential, photovoltaic and factory distribution boxes.
The width of TXOV3 adjustable voltage protector is 36mm. The control current is very convenient to install in the distribution box. The control circuit board is assembled with imported components. The product is produced according to modular standard, with excellent performance and reliability. It can work normally under abnormal voltage conditions. When the mains voltage exceeds the overvoltage action voltage value set by the protector or is lower than the undervoltage action voltage value of the protector, the protector can quickly and reliably cut off the circuit to protect the safety of the appliance. When the mains voltage returns to normal, the protector can automatically delay the power connection and restore the power supply. All functions are automatically realized without manual operation. The LED on the panel can indicate the working status of the protector. The green light of the indicator light indicates the working power supply. When the red light of the indicator is off, the power supply is normal. When the red light is on, the protection function starts to cut off the power supply. The self-reset overvoltage and undervoltage protector has compact structure and beautiful appearance, and is installed with 35MM DIN Rail

The control circuit of the automatic reset overvoltage and undervoltage protector adopts high-speed micro-low power consumption processor as the core, magnetic latching relay as the main circuit, and modular standard design. When there is overvoltage or undervoltage in the power supply line, the protector can Quickly and safely cut off the circuit under continuous high-voltage shocks to avoid accidents caused by abnormal voltage being sent to the terminal electrical appliances. When the voltage returns to normal, the protector will automatically turn on the circuit within a specified time to ensure that the terminal electrical appliances are unattended.

The protector has an inverse time limit action characteristic, and the action time is 0.1~30s.
Voltage protection range: 70~300V.
Withstand impulse voltage: 4kV (in line with the safety standards of Class III electrical appliances).
The protector has two-color light-emitting diodes to indicate the working state, green - normal voltage indicator; red - overvoltage or delay indicator.
Installation method: 35mm rail type installation, appearance modular design.
Wiring capacity: 25mm² and below insulated wire.
Comply with the standard: "Code for Design of Civil Buildings" JGJ-242 2011 Edition
Ambient temperature: -5°C~40°C;
Altitude: no more than 2000m;
Humidity: When the maximum temperature of the installation site is 40°C, the relative humidity of the air does not exceed 50%. Higher relative humidity is allowed at lower temperatures, such as 90% at 20°C. Special measures should be taken for the occasional condensation due to temperature changes.

1. Correctly connect the input terminal (IN) and output terminal (OUT) according to the product identification (the load power should be less than the rated power of the product).
2. The two-color light-emitting tube on the panel of the self-reversing overvoltage and undervoltage protector indicates the status: after the product is powered on, the light-emitting tube glows red, the OUT terminal has no output power, and after the delay protection 1-500s, it glows green. The OUT terminal normally outputs power.
3. The two light-emitting tubes on the panel of the self-resetting overvoltage protector for the upper incoming line indicate the status: after the product is powered on, the protection indicator is red, and the OUT has no output power. After the delay protection is 1-500s, the output indicator is green. , OUT normal output power.
4. When overvoltage or undervoltage occurs, the product enters the protection state, the red light is on, and the load power supply is automatically cut off; when the voltage returns to normal, after a delay of 1-500s, the green light is on, the product automatically turns on the load power supply and returns to the normal output state.

1. When the input terminal of the product is connected to the power supply for the first time, it needs to delay 1-500s to supply power to the load.
2. Product wiring: N is Null line, L is Live line, please do not connect wrongly.
3. After the product power on, don’t touch the live parts, avoid electric shock.
4. In order to prevent the contact from heating under strong current, be sure to tighten the screws of the terminal when wiring, otherwise the product will be damaged or other accidents will be caused due to excessive contact resistance, which will cause heat at the terminal.
