Noker 0-10v 4-20ma Three Phase Digital Phase Control Thyristor Power Regulator 380v For Electric Heater
Thyristor power regulator, also known as scr power controller is used to control power delivery. They are designed to vary the ac voltage across the resistive&inductive loads. The thyristor power controllers provide a smooth way of power delivery to load. Unlike conactors, not have any electromechanical movemen.Thyristor power regulator includes the back to back connect silicon rectifier(scr), trigger pcb board, current transformers, temperature transformer. By the trigger pcb board to control the thyristor by phase angle&zero cross burst two models. The current transformers detect the three phase current, as the constant current control and to be the current protection. The temperature transformers detect the heatsink temperature to protect the Scr to be safe.

Thyristor power regulator with a wide power supply rang from 260-440v, support 0-10v/4-20mA analogue input, 2 digital input, modbus communication can be used to control the scr power regulator remotely. If you need with PID temperature module, it is optional. You need not add additional temperature module anymore.
The three phase thyristor power regulator adopts 4-bit digital tube display, the eye-catching digital tube display brightness is high, good reliability. Can display all parameters and status of the power regulator, fault information. The humanized design is very convenient for the power regulator field data setting and status display.
The shell of the power controller is made of high quality cold rolled steel plate, the surface is treated with anti-oxidation, and the powder is treated with electrostatic spraying, which has the characteristics of high temperature resistance and anti-oxidation. The power regulator has compact structure design, small volume and light weight.
Three phase digital thyristor power regulator supports resistive and inductive two type loads. Some applications scr power regulator widely be used:
1. Aluminium melting furnaces;
2. Holding furnaces;
3. Boilers;
4. Microwave dryers;
5. Multi-zone drying and curing overs;
6. Plastic injection moulding requiring multi-zone heating for mainfold moulds;
7. Plastic pipes and sheets extrusion;
8. Metal sheets welding systems;
