Features

Thyristor power supply, also known as dc thyristor power supply is used to control power delivery. They are designed to vary the ac voltage across the resistive&inductive loads. The thyristor power supply provide a smooth way of power delivery to load. Unlike conactors, not have any electromechanical movemen.Thyristor power supply 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

Thyristor power supply 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 supply remotely. If you need with PID temperature module, it is optional. You need not add additional temperature module anymore.

Keyboard operation

The three phase thyristor power supply 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 scr power supply, fault information. The humanized design is very convenient for the power supply field data setting and status display.
