How To Choose A Thyristor Power Regulator?

Thyristor power controller adopts thyristor as switching element, which is a non-contact switch that can be controlled. It has the characteristics of high control precision and small impact. It is important to note that different controls can be selected according to different loads and operating environments. The common control methods include phase angle control, zero crossing control, phase angle + zero crossing control, etc. You can choose constant voltage mode, constant current mode, constant power mode, etc.
Thyristor power controller can be divided into single-phase thyristor power controller and three-phase thyristor power controller according to load type, power supply type and power supply voltage level. Next, we will introduce the problems that need attention in product selection:

1. When the load power is very small, single-phase is a very good choice, which will not cause serious three-phase unbalance to the power grid. When using a single-phase controller, consider the capacity of the circuit breaker and the cable capacity of the power supply circuit. In order to reduce the impact of the controller on the power grid, try to use 380V.
2. The total load power is large and can be divided into multiple groups of single-phase loads. Therefore, it is recommended to select multiple single-phase thyristor power controllers. In use, the thyristor power controller and load are evenly distributed to the three-phase power supply. The advantage of this is not only to maintain the three-phase balance, but also to reduce the workload of electrical equipment.
3. Three-phase thyristor power controller load generally has three connection modes, triangle connection, star connection neutral point zero, star connection neutral point zero. The high-power three-phase thyristor power controller requires copper bar or cable with large cross-sectional area and good heat dissipation conditions.
Whether you choose a single phase power controller or a three phase power controller, you need to confirm your voltage level, the required current level and the control method used. In the selection of any problem, we will provide you with professional service.
