intelligent motor protector

Extremely high reliability, very low MTTR and high MTBF figures. Low price, excellent after-sale service and long time warranty

Features

1 Take advantage of 32 digital signal processor TMS320F28035 from TI company, which provide multi-function and real-time protection. Provide friendly communicating interface with LCD display. Various data and fault are visible. Easy for operation

2 The equipment has display module, control module and current transformer module. These modules can not only be integrated but also be separated for easy installation at site.

3 The equipment has various communication functions like RS485 interface with build-in ModBus-RTU and ProfiBus-DP communication protocol and CAN interface with DeviceNet communication protocol that are optional.

4 The equipment has general protection functions like over-load, over and under-voltage, phase loose, leakage/grounding, sequence error and etc.

5 Possess direct start, double-speed start, reversible start, Y-Delta start, self-coupling reduced voltage start, soft start etc.

6 Possess multiple motor measure function.

7 Possess many kind of record function.

8 Are able to take the place of ammeter, heat-relay, current transformer, time-relay and leakage protector 

Special features

1 Adopt intelligent module designing that customer can select different protection function according to their actual requirements.

2 Combine full motor protection and control function into single system.

3 Full digital controls and it has fault self-diagnose function, which are able to delete the tolerance that caused by installation, maintenance and commissioning.

4 Programmable protections set, which can provide flexible collocation to suit different using and installation environment.

5 The voltage, current, temperature can be monitored and displayed through LCD screen and remote operation.

6 Running protection, running state can be recorded at any time to provide general protection and inspection analyze function.
