Single-phase TCR® automatic voltage regulator
Korea’s largest single-phase 150KVA class

This  TRIAC SWITCHING controlled  automatic voltage regulator is a completely stationary automatic voltage regulator that has developed a problem that cannot be solved by AVR using conventional SCR type or reactor by cutting the output voltage at a high speed by DIGITAL CONTROL circuit.

Features

RMS CONVERTOR I.C  for the  first time in the output voltage
detection circuit The TCR type automatic voltage regulator uses (RMS Converter I·C) for the first time in Korea to realize a highly reliable and durable full effective value detection circuit.The control circuit of  this product  uses PI control, so  the response speed is very fast, it does not exceed the normal deviation, and it greatly improves the initial temperature change.

Improvement of Digital Tab Change Problems
The traditional  Digital Tap Change  product  is  an AVR designed as a Triac control circuit with an output  single-volume T/R configuration, which is very vulnerable to noise and surge  on the load side, has many failures, and unstable AVR characteristics.This TCR type is a product that completely improves the problems of digital tap change such as no heat, no noise, high efficiency, and fast speed.

  • It is quiet and operates quietly.

  • Power consumption is very low.

  • Using CNP circuit, any breakdown can be prevented.

  • It’s very efficient.

  • Robust to the noise and surge.

  • The response speed is the fastest.

  • No heat generation.

  • No waveform changes.

  • It fits well with any device.
