25.7. SERIES OPERATION

26/28

Power supplies of the same type can be connected in series for higher

output voltages. It is possible to connect as many units in series as needed,

providing the sum of the output voltage does not exceed 150Vdc. Voltages

with a potential above 60Vdc are not SELV any more and can be dangerous.

Such voltages must be installed with a protection against touching.

Avoid return voltage (e.g. from a decelerating motor or battery) which is

applied to the output terminals.

Keep an installation clearance of 15mm (left / right) between two power

supplies and avoid installing the power supplies on top of each other. Do not use power supplies in series in mounting

orientations other than the standard mounting orientation (input terminals on bottom of the unit).

Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

25.8. 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 5F are connected to the

output, the unit might charge the capacitor in the Hiccup

PLUS

mode (see chapter 6).

25.9. CHARGING OF BATTERIES

The power supply can be used to charge lead-acid or maintenance free batteries (SLA or VRLA batteries).

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 13.9V 13.75V 13.6V 13.4V

Battery temperature 10°C 20°C 30°C 40°C

b) Use a 25A 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.

e) The return current to the power supply (battery discharge current) is typ. 2.6mA when the power supply is

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