High Performance Surge Stopper Power Surge Protection device

Product description

Surge protectors are mainly used to protect sensitive lines from damage caused by lightning induced voltage, power interference, electrostatic discharge and so on to protect the equipment from damage.
We use multilevel protection circuit, select brand components, use advanced production technology, with low residual pressure, sensitive reaction, stable performance, reliable work and so on. The product is standard 35mm guide rail installation, easy installation, single module can be inserted and replaced. According to different DC power sources, various specifications can be selected. It can be applied to multi-channel DC power supply system through different combinations.

Product specification

Product features

1. multi-functional overvoltage protection, lightning and overpressure are no longer afraid of disasters.

2. Small leakage current, fast response time, low residual pressure

3. with the power status indication, indicating the working state of surge protector.

4. advanced production process and beautiful appearance

Notice of product

1. in order to limit the inductive coupling between the protected part after installation and the part of the unprotected equipment, we need to make some measurements. The mutual inductance can be reduced by the separation of the inductive source and the sacrificial circuit, the selection of the loop angle and the limitation of the closed loop area.

2. when installing, pay attention to the cable entering and leaving the surge protector. The cables should be separated to avoid the two coupling of surge.

3. identify the input / output interface identifier of the lightning protector, input the external line and output the connection device.

4. lightning arresters are connected in series

Working principle of product

When the surge protector has no voltage, the impedance is very high, which means that the circuit breaker is open. When the voltage occurs, the impedance drops to a few Europe, and the surge current will flow through the surge protector and will not enter the device. At the same time, because the surge protector has a small impedance at this time, the voltage on both sides of the surge is relatively small, and because he is in parallel with the protected equipment, it prevents the equipment from suffering from large surge power. Pressure, so as to play the effect of discharge and pressure limiting.

Structure and Principle

SPD is a port, shocking protection, indoor-mounted installation, voltage-limited.

SPD hold disconnector inside, when SPD breakdown failure by over heating, the disconnector can remove from the power grid automatically, and show indication signal. When SPD is working properly, visible window display green, it display red when it breakdown and disconnect.

1P+N,2P+N,3P+N SPD consist of 1P,2P,3P SPD+NPE zero ground protection module, apply to TN-S, TN-C-S and other power supply system.

Company profile

Zhejiang Thor Electric Co., Ltd is committed to meeting the requirements of the European Union’s Waste Electrical and Electronic Equipment (WEEE) directive. This directive requires producers of electrical and electronic equipment to finance the take-back for re-use or recycling of their products placed on the EU market after 2005.
