Detailed Product Description

compressor phase sequence protector

Main function:
The product is a multifunction detection and protection instrument, and it has the functions of calculagraph, count, voltage display, over/owe voltage protection, deficient phase protection, phase sequence protection. It adopts the MCU with strong function and non-easy storage technique. It has LCD with English, intuitionist and easy to operate. It can record running time, start times, error time, error times and so on, displays current power supply voltage, and can cut off the power supply to protect the controller when over and owe voltage, deficient phase, wrong phase occur.

It can be applied to detect and protect all kinds of elevators. hoists, traveling cranes, machine tools and other instruments which start frequently, and accumulate start times and running time correctly. Converting the accumulative time and times can estimates the abrasion state of instruments, meanwhile, it can detect the power supply, cut off the power supply when the power supply is abnormal, and record the error times and accumulative time. It is in order to supply the science gist. Ensure the instruments running normally and enhance the instruments supervision.

Main function:
1. Calculagraph and count: Record the times of equipment start and the accumulative running time.
2. Voltage display: Display the current power supply voltage.
3. Over load and owe voltage protection: Cut off the power supply when the value of the voltage is too high or too low, the value can be set.
4. Deficient phase protection: Cut off the power supply when deficient phase occurs.
5. Phase sequence protection: Cut off the power supply when the phase sequence is error.
6. Error record: Record the times of error occurring and the accumulative time when error above occurs.
