(1) General
This unit employs many features previously unavailable in an industrial power supply. It
has been designed to withstand the high levels of interference found in heavy industry and
has emission levels low enough for it to be used in residential, commercial and light
industrial environments.
The power supply has a high level of reserve power. This enables loads with significant
inrush current to be supported and will also ensure that circuit breakers will trip in event of
short circuit.
A protective feature is provided which will take control as the unit approaches the power
limit due the overload or excessive temperature brought about by lack of ventilation.
If input voltage drops down to 3 x 300 V AC for 4 sec, output voltage still complies to PLC
standard EN 61131-2 (≥20,4 V DC). Use only in star-architecture TN, TT and IT networks.
Only for use in pollution degree 2 environment (Controlled Environment).
In order to take the best advantage of the
features that this power supply has to offer and to
ensure long term reliability for your equipment,
please read these instructions carefully before
installation and use. They should be retained for
future reference.

(4) Location
12
The power supply is cooled by natural convection. Top and bottom clearances should be
40 mm at minimum. Min. 6 mm side clearance is recommended, if adjacent device is
generating heat. The ambient temperature should be measured on the underside of the
unit. There will be an increase of 25 °C at the top.
If natural convection is restricted, forced cooling should be used. Mounting should
comply with EN 60950-1 point 4.7 and 4.6.1. Protection class of the case
(EN 60529).
(5) Mounting [9]
The rail should be fixed solidly so that it cannot twist when mounting or removing the unit.

Factory set, ready to use, check the connection diagrams for parallel and series
connection. Check the connection diagram for DC use
(7) Loading capacity
The nominal current is 10 A but due to the nature of industrial loading, the power supply
has been designed to support loads with high inrush currents without damage or
shutdown. Curve

Curve

shows the typical overload / temperature limit. To ensure correct convection
cooling, the unit must always be mounted with rail horizontally. Power supply is designed
to give 150 % output power (power boost) for min. 5 seconds
(8) Parallel connection [13]
Up to 3 units may be connected in parallel. In order to obtain an even current distribution,
the following points must be observed:
1) The open circuit voltage of each unit should be set to same value. Accuracy of
setting will determine how well the units share the load current..
2) The gauge and length of the cable between each power supply and the common
point should be the same.
3) Turn parallel mode switch to ON state.
(9) Series connection
Up to 2 units may be connected in series to give either 48 V DC or ±24 V DC. Check the
connection diagram
(10) Using circuit breakers on the power supply output:
For higher output voltages (series connection) and standard circuit breakers, power
supply will trip, for example the following Gladiator circuit breaker: GMCB-1C-2
0,75 A / 3 x 360 V AC - 0,55 A / 3 x 500 V AC
1,12 A / 2 x 360 V AC
