Since its establishment, we have specialized in the research and development and production of terminal blocks. The company has a large number of technical talents and production experience, among which the characteristic PCB terminal blocks are prominent. Widely used in electric power, electronics, telecommunications, transportation, industrial automation and many fields. Among them, in the inverter industry, the application range of high-voltage inverters is relatively common. The terminal properties of high current provide a guarantee for the wiring safety of the inverter, which is widely praised in the industry!

In the high-voltage inverter, in order to solve the problem of strong and weak electrical isolation between the main control system and the power unit in the terminals of the multi-level high-voltage inverter connected in series, and the electromagnetic interference between the power unit and the power unit. Unit series connection terminals of multi-level PWM voltage source inverter, adopting several low-voltage PWM variable frequency power units in series to achieve direct high-voltage output, the inverter has little harmonic pollution to the power grid, low harmonic input current, and input power factor High, no need to use input harmonic filter and power factor compensation device. The output ends of adjacent power units are connected in series to form a Y-connected structure, so as to realize the direct output of high voltage of variable voltage and frequency, and supply the high voltage motor.

The Terminal Block of the inverter is provided with a terminal slot. The nut is installed on the wiring hole in the terminal slot on the terminal block. Each terminal slot is fixed with a copper bar. The bolts and nuts are installed in the wiring holes. The terminal grooves of the terminal block are made of positive 634 epoxy-phthalic anhydride-quartz powder epoxy casting adhesive material, which has good insulation effect and excellent electrical performance. Damage and breakage, mechanical strength and good process performance, the horizontal distance between each terminal slot is more than 15 mm, and the height of the spacing is also more than 15 mm, the creepage distance is large, and the insulation effect is good. The upper part of the terminal block is equipped with plexiglass Logo screen printing, the design style is beautiful and generous, the font is simple and clear, it is convenient for customers to connect accurately, the structure is simple, and the practicability is strong.

We specialize in the production of terminal blocks, there are different types, Pcb Terminal Block and Din Rail Terminal Block. You can go to our website to browse.
