24.2. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors,
such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance larger than 1.25F are connected to
the output, the unit might charge the capacitor in the Hiccup
PLUS
mode (see chapter 6).
24.3. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 20A. 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 4A C-Characteristic breaker should be used.
24.4. CHARGING OF BATTERIES
The DC/DC converter can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series)
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 15A or 16A circuit breaker (or blocking diode) between the DC/DC converter and the battery.
c) Ensure that the output current of the DC/DC converter is below the allowed charging current of the battery.
d) Use only matched batteries when putting 12V types in series.
e) The return current to the power supply (battery discharge current) is typ. 3mA when the power supply is switched
off (except in case a blocking diode is utilized).

All parameters are typical values specified at 24V, 8.3A output, 110Vdc input, 25°C ambient and after a 5 minutes run-in time
unless otherwise noted.
