JB Series Single-Phase Thyristor Regulators

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 control and zero-cross control can be switched.
  • Rated voltage 20A to 100A, six types are available.
  • Controllability is improved by soft start, soft up-down, soft start at recovery from momentary interruption.
  • Frequency auto distinguish function, slope setting function, and lower-limit setting function are equipped as standard.
