Reynolds JJR5000 series all-digital intelligent AC motor soft starter adopts power electronics technology, microprocessor technology and modern control theory technology, which is a new type of starting equipment at the current level. This product can limit the starting current of asynchronous motor start-up, and is widely used in heavy-duty equipment such as fans, pumps, conveyors, compressors, etc., and is an ideal alternative to step-down starting equipment such as star/delta conversion and auto-coupling step-down magnetron step-down. Typical application introduction.
Water pump - use the soft stop function to alleviate the water hammer phenomenon when the pump is shut down, and save system maintenance costs.
Ball Mill – Utilizes voltage ramp start-up to reduce gear torque wear and reduce maintenance workload, i.e. save time and money.
Fan – reduces belt wear and mechanical shock, saving maintenance costs.
Compressor - use current limiting to achieve smooth start-up, reduce motor heat generation, and extend service life.
Crusher – Utilize clogging protection and quick protection to avoid mechanical failure or blockage that can cause the motor to overheat and burn out.
Conveyor Machinery – Smooth and gradual start-up with soft start to avoid product displacement and liquid spillage.
Features of the Reynolds JJR5000 series soft starters:
Three starting modes: the voltage ramp start mode can obtain the largest output torque, the constant current soft start mode can obtain the largest starting current limit, and the heavy-load start mode can be applied to the heavy-load mode.
Parking method: Voltage slope is soft, free parking.
Programmable delayed start mode, programmable interlock control.
No phase sequence requires input power.
The start time and stop time can be modified digitally.
Overcurrent, three-phase current unbalanced, overheated, phase missing, current unbalanced, overheated, phase missing functions.
Dynamic fault memory function, easy to find the cause of the fault, ** record five more faults.
You can find the largest starting current and the largest operating current online.

The reason why the inverter burns the power supply inlet end - Reynolds
1. It is necessary to consider the touch and current size of the incoming terminal, if the terminal standard is small, perhaps the conductive function of the terminal is poor, which will directly cause the current carrying capacity of the terminal to be small and heated.
2. The inlet at the end of the inlet line must be pressed well and the like, if it is not pressed, it may cause ...

Parameter setting of acceleration and deceleration time of Reynolds universal inverter
The acceleration time of the Reynolds inverter is the time required for the output frequency to rise from 0 to the high frequency, and the deceleration time is the time required to decrease from the high frequency to 0. Generally, the frequency converter uses the frequency setting signal to rise and fall to confirm the acceleration and deceleration time. The rise of the frequency setting must be limited when the motor accelerates.
