Charging of Batteries
This redundancy device is ideal for charging batteries due to the decoupling circuit built
in to the output stage which does not require a fuse or diode between the device
and the battery. Sealed lead acid (SLA) or valve regulated lead acid (VRLA) lead batteries
can be charged.
Charging Batteries
1.
Set output voltage (measured at disconnected battery) very precisely to the end-of-charge
voltage, see table below. Use the potentiometer, which is hidden behind the flap on the front of
the unit, see chapter 25.2.
2.
Ensure that the ambient temperature of the device stays below +40°C.
3.
Use only matched batteries when connecting 12V types in series.
4.
The return current to the device (battery discharge current) is typ. 11mA when the device
is switched off.
