TS40 series thyristor fast switching switchDetailed product description：

The TS40 series thyristor fast switching switch is used for contactless, high reliability fast switching in dynamic power factor compensation equipment. It can directly replace traditional contactors or ordinary thyristors, and is particularly suitable for situations that require fast and wear-resistant switching. Typical applications include lifting equipment, elevators, and welding equipment.

Compared with traditional switching switches, the TS40 series thyristor fast switching switch has the following advantages:
1. Zero crossing voltage switching, no surge current;
2 complete and compact structures, each consisting of two independent modules containing control circuits, power components, and heat sinks;
3 built-in trigger and protection circuits, full sine wave switching, no harmonic generation to achieve intelligent control of thyristor module;
Compared with ordinary thyristor switch modules, it has low heat generation, no need for axial flow fans to actively dissipate heat, no mechanical wear, no noise during operation, maintenance free components, and a long service life;
5 comes with an auxiliary control power supply, which can be directly connected to various output interfaces of the reactive power compensation controller;
A very short switching time delay of 6 can achieve real-time dynamic compensation of power factor and smooth switching of capacitors;
7 precise zero crossing phase shift control, fast response time, response time less than 15MS, reduced conduction voltage, can reduce switch losses;
Easy to install, similar to the installation of various contactors

Installation steps:
1. Check the design of the equipment to ensure that it can be used in a system with a power supply voltage of 380V or 220V
Remove the fuses of the compensation unit circuit and the secondary control circuit
The quick switching switch of the 3 TS series thyristor should be vertically aligned and ensure sufficient cooling conditions for the device
Press down on the snap spring of the front plastic cover and remove the cover
5. Connect according to the wiring diagram
6. Plastic cover installed in place
Insert the 7 fuses in sequence, and note that the capacitors are now powered on
After the main circuit is powered on, it can be put into operation. Note that the module must be in the off state before powering on

Precautions for use:
Choose the correct module model based on the compensation power to ensure that the module current capacity is within the rated safe usage range
This device is designed for 380V AC systems and should not be used under excessive voltage to avoid permanent module failure. Before putting it into operation, it is necessary to check whether the system power supply voltage is within the working voltage range of the module
When installing the switch inside the cabinet, attention should be paid to ventilation conditions and it should not work in a completely enclosed cabinet
The equipment should not work in environments with corrosive gases, and attention should be paid to the insulation of the wiring in high humidity environments
Before powering on, carefully check the reliability and correctness of the wiring
Before powering on the switch, ensure that the control terminal is in the off state
