The JS/JT series is small and lightweight thyristor regulators with built-in firing unit for high density of mounting on instrumentation panels.
- Wide selection from 10A to 1000A on both single-phase and three-phase load applications
- Two control systems of phase-angle firing system and zero-cross firing system
- 4 kinds of feedback type of voltage feedback, current feedback, power feedback and without feedback are available in accordance with the characteristics of heating element on the phase-angle firing system
- Two kinds of zero-cross firing system, conventional type and modulation type, are available for sensitive power control
- Protection functions including thyristor gate-off and rapid fuse are built-in.
