Low voltage capacitor bank panel with Thyristor switch

ZD-DWT device is suitable to low voltage system (220V-1000V)of low power factor and harmonic pollution. The main function are  reactive power compensation harmonic depression . ZD-DWT series  adopts structure and on-off to track load variety automatically according to load characteristic and changing condition. It can remove harmonic and keep the system power factor at the best state anytime. The equipment can be found widely used among numerous machine where load changes greatly including electric welding machine, injection molding machine, rolling mill and air compressor.
The device is consisted of controller, tryristor, capacitors and reactors. The core of controller adopts DSP,  which can analyze and calculate of electric system data sampling, and create control instruction of capacitor switch, then reach target power factor. 

Module design technology. It is composed of ZD-MTK modules with intelligent reactive power compensation function.

1. Enclosed module design. Realize the standardization and modularization of products
2. Safety. The closed design of the exposed electrified part makes the product  safe and reliable.
3.Efficency. Rapid production,installation and service because of simple wiring,module design and capacitor bank panels installation. Improve efficiency greatly.
4.Fuse instead of tranditional mirco circuit breaker, can improve ability of switching on and off, and improve the electrical protection mechanism.
5.RS485 interface, standard MODBUS Protocol, computer remote monitoring, history recording function. Can set parametre easily and use manual switching rapidly.
6. No inrush current impact during the process of switching capacitor with high power. Adopt temp. control Tech,ensure swiching will be closed while Tryristor 's Temp excess.
7.The capacitance and reactance are precisely matched and independent to each other, which can effectively inhibit a variety of high-order harmonics and protect the circuit and capacitor from impact damage.
8.There are two groups of capacitors in the module, which can realize any combination of co-compensation and sub-compensation. The centralized combination and decentralized control ensure the 3-phase tend to an ideal balance ,and ensure the stability of voltage supply after compensation.
