Single Phase Thyristor Power Controller

Product Description

The Dydac Thyristor Power Controller is a heavy duty, fully Digital or Analog one, two or three phase power control unit for controlling the voltage applied to loads such as heating elements, thus, allowing temperature control while eliminating contactor switching and over/under heating.

Dydac offers wide range of Thyristor Power Controllers in Single Phase, Double Phase Three Phase Star or Delta , Three Phase Star with Neutral .

Features

1. Soft start bake out feature prevents moisture at start up

2. Current Limit , Phase Loss Trip, Over temperature Trip

3 Microcontroller Digital Programmable Thyristor Power Controller with Percentage Display. Program setting of Current Limit, Soft start etc by front keys
