CT5.121

C-Series

The power supply can be used to charge 12V lead-acid or maintenance free batteries.

Instructions for charging batteries:

a)

Ensure that the ambient temperature of the power supply is below 45°C

b)

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

13.9V

13.75V

13.6V

13.4V

Battery temperature

10°C

20°C

30°C

40°C

c)

Use a 10A circuit breaker (or blocking diode) between the power supply and the battery.

d)

Ensure that the output current of the power supply is below the allowed charging current of the battery.

e)

The return current to the power supply (battery discharge current) is typ. 5.5mA when the power supply is

switched off (except in case a blocking diode is utilized).

The unit is tested and approved for branch circuits up to 30A (U.S.A.) and 32A (IEC). An external protection is only

required, if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In

some countries local regulations might apply.

If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of

the circuit breaker. A minimum value of 6A B- or 3A C-Characteristic breaker should be used

The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.
