MPS is new multi-functional power switching module for stand-alone power supplies. It can be configured to operate as a charge controller, load controller or diversion controller by simple toggling of DIP switch settings.
A single MPS unit can control up to 80 A of current at 12, 24 or 48 V and switching can be set for pulse-width modulation or two-point series switching. When configured as a diversion controller, MPS can also control a diversion load for wind and micro-hydro turbine systems.
MPS offers integrated, adjustable low voltage disconnect as a load controller and sophisticated overcharge protection as a solar charge controller. The new flexible power electronics allow for positive or negative grounding.
The power switch is a fundamental unit within Modular Power Management family. Multiple MPS units can be operated together with the help of MCU modular control unit. This allows multiple strings of solar inputs to be used to charge the same battery bank at an aggregate charge current of up to 640 A.
MPS is a cost-effective, simple, yet versatile power switch that is a valuable solution for stand-alone solar, wind, micro-hydro or hybrid power supplies.

Part 7. Function description
1. Battery System Voltage Detection:
MPS can be used in 12V, 24V, 48V battery systems. The nominal system voltage is detected automatically when connected to the battry bank.
2. System Grounding
MPS can control loads in positive and negative grounded systems.
3. Displayer Function:
4. Overload and Short-Circuit Protection
MPS advanced overload protection allows overload for a limited time, to enable inrush current when switch on loads: Diversion load will be reconnected automatically after one minute.
| Load current in % of nominal current | Time of switch off |
| 110% to 150% | 120sec |
| 150% to 200% | 12sec |
| Short current | Immediately |
5. Overtemperature Protection:
To protect MPS from overheating and damage due to overtemperature , MPS will switch off the diversion load. Overheating can happen if MPS's ventilation grill is blocked or ambient temperature is too high.
