Fault Simulation
Simulation of voltage, currents and temperature faults enables relay testing.
This simulation Program allows testing and selflearning of the MPS 3000.
Dimensions
& Weight
Vertical:
W-135, H-310, D-160, 3.3Kg
Available types
MPS-3000/P - Protection only system
MPR-3000/C - Protection & Control System
MPS-3000/C
Similar to the MPS-3000/P except with 16 discrete inputs to enable full control (start, stop, rotation direction change, etc.)
The MPS-3000 also incorporates two additional protection functions:
- Control Circuit Open (74)
- Welded Contactor (74)
