(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-02A-1P-24V-S 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.
This equipment shall be connected directly to the d.c. supply system earthing electrode
conductor or to a bonding jumper from an earthing terminal bar or bus to which the d.c.
supply system earthing electrode is connected.

The power supply is cooled by natural convection. It is important to maintain clearance
to other components as much as possible to ensure best performance and long term
stability. Top and bottom clearances should be 50 mm at minimum. Side clearance to
other equipment should be 20 mm or > 50 mm if that equipment is heat generating. 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
11
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 [7]
The rail should be fixed solidly so that it cannot twist when mounting or removing the
unit. Mounting instructions [5], Removing instructions [6].
(6) Switching on
Factory set, ready to use, check the connection diagrams for parallel and series
connection.
(7) Loading capacity
The nominal current is 2,5 A (60W) 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 [8] shows the typical current / voltage curve, decreasing part of the
curve shows the current limitation. Curve [11] show the current / temperature limit.
(8) Parallel connection [9]
Up to 5 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. The gauge and lenght of the cable between each power supply and the common
point should be the same. Units should only be used in parallel where the supply exceed
110 VAC.
(9) Series connection
Up to 2 units may be connected in series to give either 48 VDC or +/-24 VDC. Check
the connection diagram [10].
(10) Using circuit breakers on the power supply output:
On the short circuit, the power supply will trip, for example, the following ABB-STOTZ
circuit breaker:
