Single Phase JU Series Single-Phase Thyristor Regulator

Product Details

Our company has created a niche in the field of offering JU Series Single-Phase Thyristor Regulator.Features: Compact structureCompact, lightweight and high panel installation densityOptionsThe options of heater disconnection alarm function and current limit function are available.Phase-angle firing/zero-cross firingThe phase-angle firing system and the zero-cross firing system are selectable. The running by the phase-angle firing system at the initial stage and by the zero-cross firing system at the normal stage is possible.Zero-cross firing systemWith the delta-sigma modulation, which controls every 1 cycle, the fine control like the phase-angle firing system is possible.Setting unit (option)Display of various parameters, voltage/current/ power and change of the feedback system are possible.Various protections functions built-inThe thyristor element is protected by melting of the rapid fuse for short-circuit of load, and by gate-off for over-current. For models with a cooling fan built-in, alarm is activated and output is stopped for abnormal heat-sink temperature.Self-diagnosis function built-inThe self-diagnosis function is built in for abnormal operation, abnormal thyristor element and abnormal power supply.
