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.

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 > 0.4F are connected to the output,

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.

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.

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).
