(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 PSU-40A-3P-24V-H 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 VAC for 4 sec, output voltage still complies to PLC standard
EN 61131-2 (≥ 20,4 VDC).
Use only in star-architecture TN, TT and IT networks.
Only for use in pollution degree 2 environment (Controlled Environment).

Remark! If potential free alarm contact is closed and potential free preventive diagnostics
contact is open (End of Lifetime), we recommend that power supply should be replaced.
(4) Location
The power supply is cooled by natural convection. Top and bottom clearances should be 50 mm
at minimum. Min. 6 mm side clearance is recommended when loaded permanently with full
power. 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
IP20 (EN 60529).
(5) Mounting [10]
150%
The rail should be fixed solidly so that it cannot twist when mounting or removing the unit.
Mounting instructions [8], Removing instructions [9].
(6) Switching on
Factory set, ready to use, check the connection diagrams for parallel and series connection.
Check the connection diagram for DC use [16].
(7) Loading capacity
The nominal current is 40 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
[11] shows the typical voltage / current curve. Decreasing part of the curve [11] shows the
current limitation. Curve [12] 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 [13].
(8) Parallel connection [14]
Up to 3 units may be connected in parallel. 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. Turn
parallel mode switch to ON state. The gauge and lenght of the cable between each power supply
and the common point should be the same.
(9) Series connection
Up to 2 units may be connected in series to give either 48 VDC or +/-24 VDC. Check the
connection diagram [15].
(10) Using circuit breakers on the power supply output:
Using circuit breakers on the power supply output side up to 28 VDC we recommend MOD-EAC
module. For higher output voltages (series connection) and standard circuit breakers, power
supply will trip, for example the following ABB circuit breaker:
