Comprehensive Digital Motor Protection Relay with the MCU (Microprocessor Control Unit)
Providing real-time processing and high precision
Applicable to invertor circuits
It can be installed in the downstream of a speed driver where harmonic
noise exists. The allowable frequency range is 10 to 400Hz.
A harmonic filter must be used if THD (Total Harmonic Distortion) is over 30%.
* Set the ground fault mode off to avoid the trip due to current unbalace.
* Voltage parameters are not available. Power measurement accuracy is not guaranteed.
Function to store the cause(s) of failure / Fault
Up to 5 motor failure events may be saved in the system, so that the failure history can be easily identified.
One-Body Type and Separate Body Type
The display unit can be separated from the device to mount on the face of the panel, which enables the
access to the unit without opening the door. All the functions remain unchanged after the separation.
Communication function (RS485 Modbus and 4~20mA output)
With universal RS485/Modbus communication types, it is possible to establish various system and
communication networks.
Analog current signal (4~20mA) output is compatible with conventional TD(Transducer) based system.
A wide range of reset functions
Manual/Automatic/Electrical reset functions are provided for user convenience.
Date information display
When a failure occurs, the date and time of failure occurrence are saved in the system to accurately identify
the date of motor failure.
Password setting
When changing the set values, a password must be inserted.
Total operating time and operating time setting
When the predefined operating time has elapsed, related information is displayed so that operators may
replace
the motor bearing and check the refueling cycle.
Quick Setup
Same setting for another devices in different panels can be done simply via the display unit.
