Three-phase TCR® automatic voltage regulator
Korea’s  largest capacity of three-phase 600 KVA

The TCR type  automatic  voltage fixer was developed in November 1983 and has made many progress to this day with absolute praise and acclaim from customers. Wherever you use AVR, you can easily see Taijin Tech’s TCR-type automatic voltage regulator. Taijin Tech Co., Ltd. has won and delivered 600 KVA AVR, the largest production capacity in Korea among  TCR-type production capacity. This  600 KVA  AVR features  automatic static circuits and state-of-the-art protective devices, which are reliable in functionality and characteristics.

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 operates quietly.

  • Power consumption is very low.

  • Since it usees CNP circuit, there is risk of breakdown.

  • Highly efficient.
  • Robust to the noise and surge.

  • The response speed is the fastest.

  • No heat generation.

  • No wave-form changes.

  • It fits well with any device.
