3-phase ac motor controller
2016 new developed multi-functional motor controller.
1. Internal thyristor SCR controlling.
2. Simple distribution: Circuit Breaker-Our Contactor-Motor
3. Can substitute all electromagnetic contactor without any load selection.
4. Single product can control motor forward and reverse.
5. Both capacitive and conductive load can be controlled.
6. Real time display the current and voltage value.
7. Maintenance-free, convenient for your operation.
8. Long use life can save your much cost.
JNTJ series of motor multi-functional controller (hereinafter referred to as multi-controller) is our latest type of motor contactless controlling products with multi-purpose which designed according to the electrical control industry and the actual needs of crane industry.
JNTJ series of multi-controllers adopt power electronics technology, with intelligence、no-spark、strong anti-interference ability、long-life and other charactoristics. Especially suitable for harsh working condition and frequent movement of electrical control systems
JNTJ series of multi-controllers apply to three-phase electric control circuit and the motor CW/CCW rotation control circuit with AC voltages is less than 500V, frequency range 45Hz~250Hz. This series have the protection of overcurrent、overvoltage、undervoltage、 less phase、load imbalance、overheating and other intelligent detection, fault alarm and regulation function, can substitute the electromagnet contactor equipped with all kinds of protection device, which without any load selection.
1. Real-time voltage, current display.
2. Overvoltage、 overcurrent、 undervoltage and alarm.
3. Overcurrent protection delaying is adjustable.
4. Maintenance time set alarm when ex-works, maintenance-free intermediate.
5. Internal MTC control, no arcing when it is on-off, with good electromagnetic compatibility.
6.Wide voltage design, the action time and sensitivity will not be affected due to power fluctuation.
7. On-off frequency is up to 50 times per second, no mechanical vibration, long use life, high reliability.
8. LED show on panel, watch easily and directly.
9. Intelligent air cooling, it can still work when ambient temperature is up to 55 centi-degree.
