Single-phase thyristor regulator JB series

Contact Us

The JB series is a compact and relatively inexpensive single-phase thyristor regulator (without feedback). Six models are available with rated current ranging from 20A to 100A, making them easy to use.

Compact, lightweight, and simple body with high performance

  • Compact, one-piece design requires little installation space and allows for easy wiring
  • Switching between phase control and frequency division control is possible
  • Six models available with rated current from 20A to 100A
  • Improved control with soft start, soft up/down, and soft start functions when recovering from momentary power interruption
  • Equipped with automatic frequency discrimination function, gradient setting function, and lower limit setting function as standard features

Other features

A wide range of accessories are available.
