1. The protector is installed on the base of 8PFA. The base is equipped with two M4 screw holes, which can be installed independently or using HT35 rails.
2. Indicator light: 2 indicator lights, divided into power indication and normal operation indication.
3. Outer dimensions: 50mm x 40mm x 57.5mm.

Overvoltage protection, also known as overvoltage protection, is a type of protection that disconnects the power supply or reduces the voltage of the controlled device when the protected line voltage exceeds a predetermined maximum value. Overvoltage protection is usually configured with varistors. When the transient high voltage generated by the circuit is applied to both ends of the varistor, the resistance of the varistor becomes infinitely small, which makes the varistor conduct and passes the large current generated by the circuit to earth through the ground wire, thereby protecting the power supply device from being affected. High voltage damage.

It should be noted that overvoltage protection will start immediately and overcurrent protection will have a delay of about one second. This is because if the power supply works normally, such as a sudden short circuit in the load of the power supply, the instantaneous current output by the power supply is several times or several times the rated current value. It can be considered as a current surge, far exceeding the overcurrent protection. Value, but this time does not want overcurrent protection to work. But after the short circuit is released, the voltage automatically returns to normal. Therefore, when designing over-current protection, current surges during sudden short-circuiting must be avoided, and only the duration of the output over-current should be considered to start the over-current protection.
