Korea's first digital power regulator, developed in 2000.
The trusted standard, best-seller for 26+ years.
Proven technology, best-seller for 26 years since Korea's first launch in 2000
Korea's first digital power regulator with a microprocessor, widely applied in batteries, semiconductors, steel, solar, and display industries. Far superior stability and precision compared to conventional analog.
Proprietary compensation algorithm that overcomes the precision limits of zero-crossing control. Patented technology that dramatically improves output accuracy relative to input signal.
Korea's first 3-digit FND display to show output values and alarm messages directly. Immediately identify fuse break, load break, heatsink overheat, over-current, SCR fault and more for vastly improved maintenance convenience.
Features easy, low-cost maintenance and compact design. Perfect control performance in any field condition, with reliability verified as the #1 cumulative seller for 26 years.
