CHANGES FROM MPC2000 TO MPS3000
1. Four programmable discrete (digital) inputs to the MPS3000 (one, before – for Key only).
2. Four programmable Analog outputs
3. Four Programmable Analog Inputs with four new trips (protections)
4. Real time clock.
5. Statistical Data of last 10 trips with time & date stamp.
6. Larger Display.
7. Switch Mode power supply for AC or DC (one unit from 85V to 230V)
8. Baud Rate (MODBUS) up to 19200 bps.
9. MPS3000 includes 10 Temperature sensors. Two models: one (Standard) model with 10 RTD (as
before), second (optional) model with 6 RTD and 4 thermistors. Must be ordered from factory. Field
modifications are not possible.
10. Control function (for MPS3000-C) with MODBUS function 6 and 16. Functions 1,2,5,15 are canceled.
11. MODBUS new group of 20 user selected actual data parameters for fast scanning.
12. Unbalance calculation using Negative and Positive Sequence instead Imax and Imin.
13. UNBALANCE MIN T (unbalance minimum time = 1..30 sec.) new parameter to prevent too fast response.
14. Standard “American” Thermal Overload curves
15. RTD Bias (of thermal overload)
16. Unbalance Bias (Of Thermal Overload)
17. New program for current, voltage and temperature fault simulation . (useful for testing and for learning
the MPS3000, "on the engineer table")
18. Power measurement even if single phase voltage is connected (V1n,V2n,V3n = V12)
19. KWH (Energy) Display and KWH output (pulse relay)
20. Programmable Output Relays.
21. Too Many Starts Pre Alarm can be configured to energize output relay.
22. (I > 0) After Trip can be configured to energize output relay B (to trip upstream breaker).
23. Every fault group can be configured to energize output relays A & B (similar to MPR6).
24. NO START PROCESS new setting of STARTING METHOD, to allow switching to run, if I>= 10%.
25. Capture and display of minimum and maximum RMS average (of three phases) voltage and current.
Capture of minimum and maximum frequency.
26. G/F During Start setting, new feature to eliminate nuisance ground fault tripping when residual CT
connection (not required with Core Balance) is used.
27. New Emergency Restart function. Reset of Thermal capacity by pressing reset twice is canceled.
28. Modified Restart- after mains failure or Auxiliary Power Supply failure.
29. Separate Aux Power Supply and Control Voltage (option –S).
30. KVARH, added.
31. New setting parameter UV ACTIVE AT STOP, to enable/disable Under Voltage protection at stop.
