Single-phase 26mm · Three-phase 115mm
Korea's smallest SCR digital power regulator
A safe and reliable ultra-compact digital power regulator that replaces unprotected SSRs
The smallest digital power regulator in Korea with 26mm width for single-phase and 115mm for three-phase products. Easy installation even in cramped control panels.
Uses SCR devices instead of the TRIAC used in SSRs, ensuring superior durability and reliability with longer service life and stable operation.
Detects power element faults and notifies via alarm. Unlike SSRs which lack this feature and pose fire risks, MINI detects abnormalities immediately to ensure safety.
High precision and stability through waveform loss compensation control and years of digital power technology. 3-color LED for at-a-glance status monitoring.

When a power element fails, control is lost and the main power flows directly to the heater, potentially causing a fire.
Detecting power element failure is directly related to safety. Unlike SSRs which cannot detect element failure, MINI uses CPU operation and its own CT to detect power element abnormalities, ensuring safety.
SSRs require an external CT or load break detector for load break detection, but MINI has a built-in CT which reduces wiring work and wiring errors, improving customer convenience.
Waveform loss compensation control is built-in as standard, improving control precision.
Years of accumulated digital power technology since the development and release of the digital power regulator ensures extremely high stability and reliability.
