Note: If a started cycle could not be finished, the regulator stores the lacking cycle time and uses
the next chance to finish.
All settings are ambient temperature compensated (-24mV/°C) target accuracy: +/-5°C
minimum charging voltage 13.0V, maximum charging voltage 15.0V
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:
MPS is available in two versions:
Nominal charging current
Overload and short circuit protection:
MPS advanced overload protection allows overload for a limited time, to enable inrush current when
switching on:
Charge current in % of nominal current:
<110%
110% to 150%
>150%
Over temperature protection:
PCB temperature
>95°C
80°C(176°F) to 90°C(194°F)
<80°C
Battery over-voltage protection:
Activates over-voltage procedure if battery voltage is more than three times per second higher than
15.5V. Optional accessory MCU can adjust this parameter.
Type
Temperature-controlled current reduction by PWM. (If
power electronic temperature is below 80°C(176°F),
no limitation of current occurs).
Reduces charge current by PWM to <100% I nominal and
temperature controlled current reduction.
Reduces charging current by applying PWM to keep
temperature below 90°C(194°F)
