PRODUCT DESCRIPTION

Main Features

1. With two models of external bypass and internal bypass, it is convenient for customers to choose.

2. Main terminal connecting line is fixed directly by screws, which is safe and reliable.

3.The control line alone power supply is more stable, can make the main power supply range covers 220-480V without changing the machine.

4.LCD display, standard Chinese and English options, more convenient to use, can also be customized according to customer requirements of other language types.

5.Three groups  motor parameters can be switched, more convenient to use.

6.With PTC temperature sensor interface, motor protection is more comprehensive.

7.Equipped with RS485 communication interface as standard, it is more convenient for group network control.

8.10 sets fault records, Easier to find problem .
