2.1 MPS features:
Battery System Voltage Detection
MPS can be used in 12 V, 24 V, or 48 V battery systems. The nominal system voltage is detected
automatically when connected to the battery bank.
Charge Cycles:
Note: If a started cycle could not be finished, the controller stores the lacking cycle time and
uses the next chance to finish.
All settings are ambient temperature compensated (-24 mV/K per cell) target accuracy: +/-5°C,
maximum charging voltage 15.0 V (12V system).
System Grounding:
MPS can be used in positive and negative grounded charging systems. Grounding is selected
by wiring of your MPS, see details in chapter 2.3.2.
Charging Current:
MPS80
80 A
MPS45
45 A
MPS is available in two versions:
Overload and Short Circuit Protection:
MPS advanced overload protection allows overload for a limited time, to enable inrush current
when switching on:
