HIGH QUALITY CONTACTLESS CONTACTOR FOR CRANE, MULTI CONTROL CONTACTOR
Product Description
JNTJ series (one-way and forward-reverse rotation)
Motor multi-function controller
JNTJ series motor multi-function controller (hereinafter referred
to as multi-controller) is the most new contactless multi-purpose motor
control product designed by our company according to the actual needs
of the electrical control industry and the starting machine industry. JNTJ
adopts the powerelectronic technology, withtheadvantagesofintelligence,
no spark, strong anti-interference ability, long life, etc., especially for
electrical control system of frequent action and bad working environment.
JNTJ series multi-controller is suitable for three-phase electric control
circuit and positive and negative motor rotation control circuit with AC
voltage less than 500V and frequency range of 45Hz~250Hz. It has such
intelligent detection functions for overcurrent, overvoltage, undervoltage,
phase loss, load imbalance, overheating, fault alarm and adjustment
functions, which can replace electromagnetic contactor with the extra
installation of various protective devices, without loads differentiation.
Features:
1: Real-time current and voltage display;
2: Over-voltage,over-current,under-voltage,three-phaseunbalanced
alarm;
3. One machine can realize positive and negativemotor rotation
function,delay switchingsettingfunction, motorprotectionfunction,
RS485 communication function, etc.;
4: Simplified power distribution, circuit breaker-multi-controller-
motor, no unnecessary components;
5. Design life of more than 3 years, with 3 years maintenance-free
and delivery warranty of 18 months;
6: Wide voltage design, reduced purchase cost, normally use even
if the environment temperature above 90 degrees.
Advantages compared to similar manufacturers:
1: Other manufacturersall just usesimplerelay trigger,only replaces
the contactor. Our company's products are the only one which
use chip (American) design, so cover contactor, thermal relay,
delay relay,motorprotectorandother functions,theonly manufacturer

due to relay trigger.Our company adopts American industrial
high temperature chip, the product can work reliably in 90-120
degree temperature.
3: Our products have fault code display, no need to troubleshoot
on-site fault as the fault code displays fault.
4:Our products have CCC certification and CE certification.
