Features

Furnace temperature thyristor heating controller, 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. Scr 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.

Terminals

Furnace temperature thyristor heating controller 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.

Keyboard operation

The three phase furnace temperature thyristor heating controller 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.

Dimension

The shell of the three phase furnace temperature thyristor heating 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.
