23.5. CHARGING OF BATTERIES
The power supply can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VRLA batteries are
needed in series connection.
Instructions for charging batteries:
a) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge
voltage.
End-of-charge voltage 27.8V 27.5V 27.15V 26.8V
Battery temperature 10°C 20°C 30°C 40°C
b) Use a 10A circuit breaker (or blocking diode) between the power supply and the battery.
c) Ensure that the output current of the power supply is below the allowed charging current of the battery.
d) Ensure that the ambient temperature of the power supply stays below 40°C for AC 120-240V mains and below
35°C for AC 100V mains.
e) Use only matched batteries when putting 12V types in series.
f) The return current to the power supply (battery discharge current) is typ. 8mA when the power supply is switched
off (except in case a blocking diode is utilized).
