Features
JB series is compact and relatively low-priced single-phase thyristor regulator (no feedback). Rated voltage 20A to 100A, six types are available for your convenience and used readily.
- Compact all-in-one type, so it doesn’t take much space to install and wiring is also simple.
- Phase-angle firing control and zero-cross firing control can be switched.
- Rated voltage 20A to 100A, six types are available.
- Controllability improves with soft start, soft up-down, and soft start upon recovery from momentary interruptions.
- Standard features include frequency auto distinguish function, gradient setting function, and lower-limit setting function.
