24.7. SERIES OPERATION
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.
Earthing of the output is required when the sum of the output voltage is
above 60Vdc.
Avoid return voltage (e.g. from a decelerating motor or battery) which is
applied to the output terminals.

Restrictions:
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 (terminals
on bottom of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
24.8. 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).
24.9. 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.

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).
