How is reactive power generated
In AC circuits, the power factor arises because inductive or capacitive elements are introduced into the circuit. Then it exists in the form of active power, reactive power, apparent power and so on. The simple understanding of reactive power is the energy exchange between the power supply and th...Read more -
Note in the use of thyristor power controller
Thyristor power controller is widely used, which is a kind of energy-saving and environmental protection products.

The causes of harmonics distortion
The word “harmonics” is a broad term and is used in many different industries. Unfortunately, certain electrical problems are incorrectly blamed on harmonics. These harmonics should not be confused with radio frequency interference (RFI), which occurs at much higher frequencies than harmonics. Po...Read more -
Introduction of the PID temperature module of the scr power regulator
Most of the power controllers on the market do not contain PID temperature controllers, in the process of use, the value of your PT100, K, S, B, E, R, N sensor signal is converted to 4-20mA/0-5v/0-10v as the analog input signal of the power regulator for control. The power controller proportion...Read more -
