(1) General
This unit employs many novel 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 MPS10 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 the event of a short circuit.
For manual control of the output voltage, two push buttons are provided. Operation of the red “TESTSTOP” button will turn the
voltage off. Operation of the green “RESTART” button will turn it on.
WARNING!!
the output voltage always comes on when the supply is turned on.
An alarm contact is provided which will open as the unit approaches shut down due to overload or excessive temperature brought
about by lack of ventilation. If no action is taken and the temperature continues to rise, the unit will shut down but may be reset
after cooling by means of the “RESTART” BUTTON.
When the power supply is connected to the mains, there is no inrush current. The supply will monitor low supply voltage and phase
loss.
The power supply can be configured with DIP switches to work with battery back-up. A lead-acid battery can be held on float charge
with the alarm contact operating as low voltage release to prevent deep discharge.
NOTE: The unit is intended to be connected to star-connected network where the main voltage is 3 x 400 VAC (Max. Line to Earth
voltage 250 VAC).

(4) Operating modes
Conventional power supply
The factory setting is for conventional power supply operating
mode
[12]
with a no load voltage 24,15 volts. DIP switches 1 and
3 are ON, 2 and 4 are OFF. Continuous overload, high ambient
temperature or a load current greater than 13 amps taken for longer
than 400 ms, will cause the unit to trip into the RESTART mode.
As the unit approaches shutdown, a pre-warning will be given by
the alarm contact and the yellow “CURRENT LIMIT” led
Battery backed power supply
The battery backed power supply
[13]
can be set by changing the
DIP switches 2 and 4 to ON and 1 and 3 to OFF. The load will be
energised by the power supply when the mains supply is on and
by the battery should the mains supply fail. If, due to overload, the
terminal voltage falls below 19 volts, the power supply trips to the
RESTART mode. The alarm contact will release the low voltage
relay and isolate the battery from the load. If due to mains failure,
the battery discharges to below 19 volts, the alarm contact will
release the low voltage relay and prevent deep discharge of the
battery. When the mains is restored, the power supply will start
automatically and the battery will be charged with the residual
current available after the load is supplied (I
bat
= I
max
- I
load
)
(5) Location
The power supply should be mounted horizontally (connection
terminals facing downwards). The power supply is cooled by
natural convection. It is important to maintain clearance
dimensions equal to or greater than the minimum shown on the
diagram
[14]
to ensure best performance and long term reliability.
Side clearance to other equipment sholuld be 25 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 20°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 IP20 (EN 60529).
(6) Mounting
Rail mounting
[15]
The rail should be fixed solidly. The two 20 mm diameter washers
supplied should be fitted under the screws and will help to prevent
distortion of the rail. Mounting instructions

, / Removing
instructions
[17]
.
Screw fixing
[18]
A pair of fixing brackets, Art. No. 89500 must be attached to the
power supply with the screws provided. The keyhole brackets will
accept four M5 screws. (Screws are included).
(7) Switching on - conventional power supply
Factory set, ready to use. Check 10 and 11 for parallel and series
connection.
(8) Switching on - battery backed power supply
(lead acid)
Check the recommendations of float charge voltages from the
specification of the battery manufacturer. If the values are not
available,
the
float
charge
voltages
can
be
set
with
U-ADJ.-adjustment potentiometer as follows:
For maximum lifetime, the battery temperature should not exceed
35°C and must never exceed 40°C. NiCd batteries must not be
used.
The low voltage release relay and the battery fuse module are
available from Murrelektronik.
Always use the correctly sized fuse or circuit breaker and connect
as near to the battery as possible. Ensure that the battery
compartment is ventilated. The power supply can be damaged
by wrong battery polarity. See connections
[25].
When the mains
is disconnected, the power supply and the low voltage release
relay discharges the battery by Art. No. 89510 / 150 mA and Art.
No. 89513 / 700 mA.
(9) Loading
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
[19]
shows the typical voltage / current curve. Curve
[20]
shows
the voltage / current response to dynamic 50 ms load. Curve
[21]
shows the voltage / current response to a dynamic 400 ms
load. Curve
[22]
shows the overload / temperature limit. To
ensure correct convection cooling, the unit must always be
mounted with the terminals at the bottom.
(10) Parallel connection
[23]
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.
The gauge and lenght of the cable between each power supply
and the common point should be the same. Operation is based
on the electronically controlled 0.5% voltage / current slope.
Alarm contacts should be connected in series. By redundant use,
outputs must be connected through diodes, so that alarm
contacts will retain their function, Art. No. 896014. When using
a battery back-up, it is advisable to connect each power supply
to the battery positive terminal through it’s own 16 A fuse. Units
should only be used in parallel where the supply exceed 375
volts.
(11) Series connection
[24]
Up to 2 units may be connected in series to give either 48 VDC
or +/-24 VDC. Alarm contacts should be connected in series.
(12) Setting the output voltage
The open circuit voltage is factory set to 24,15 VDC. Clockwise
rotation of the “U-ADJ” potentiometer
[6]
will increase the
voltage. If the setting exceeds 28 VDC, the overvoltage
shutdown protection could operate. If this happens, reduce the
setting and press the green “RESTART” button.
(13) Alarm contact
[9]
The alarm contact is closed during normal running and opens for
phase failure, supply failure, low supply voltage, output short
circuit, overload pre-warning, high output voltage or low output
voltage when used in battery back-up mode
Note !!
The contacts can only be used on DC. Maximum 60 VDC
at 0,2 A. The resistance is approximately 3 - 6 ohms.
(14) Using circuit breakers on the power supply output
On short circuit, the power supply will trip, for example, the
following ABB-STOTZ circuit breakers:
-S201-C2A
-S201-Z4A.
We reserve the right to change this specification.
