Motor multi-functional controller, solid contactless contactor Ⅰ。Brief Description: JNTJ series of multi-controllers take the power electronics technology, with the intelligence、no-spark、strong anti-interference ability、long-life and other charactoristics. Especially suitable for frequent starts and harsh working condition of electrical control systems. JNTJ series of multi-controllers apply to three-phase electric control circuit and the motor reversing control circuit with AC voltages is less than 500V, frequency range 45Hz~250Hz. This series of multi-controller is with intelligent detection for overcurrent、overvoltage、undervoltage、 less phase、load imbalance、overheating, fault alarm and regulation function, which can replace all the electromagnetic contactor equipped with all kinds of protection device, which without any load model selection. Features: 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 thyristor 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 indicates on-off state, watch easily and directly. 9. Intelligent air cooling, it can still work when ambient temperature is up to 55℃. Supply the model JNTJ-100 JNTJ-100-S JNTJ-150 JNTJ-150S JNTJ-200 JNTJ-200S JNTJ-300 JNTJ-300S JNTJ-400 JNTJ-400S JNTJ-500 JNTJ-500S JNTJ-600 JNTJ-600S JNTJ-800 JNTJ-1000etc. Welcome to call for model selecting information. |
