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.
