(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.

This 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 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 3x400-500 VAC (Max. Line to

Earth voltage 290 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 52 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 LVR- voltage, 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

7, 8

failure, the battery discharges to below LVR-voltage, the alarm

9, 10

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

- I

)

48 VDC

(5) Location

The power supply should be mounted horizontally (connection

7, 8

terminals facing downwards) and it is cooled by natural convection.

9, 10

It is important to maintain clearance dimensions equal to or greater

(+/- 24 VDC)

than the minimum shown on the diagram [14] to ensure best

performance and long term reliability. Side clearance to other

equipment should 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

The power supply must be installed vertically, with the input and

the output terminals at the bottom.

Rail mounting [15]

The delivered rail should be fixed solidly. Mounting instructions

[16], / Removing instructions [17].

Screw fixing [18]

A pair of fixing brackets, Art No. 89504 must be attached to the

power supply with the screws provided. The keyhole brackets will

accept four M5 screws. (Screws are included).

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 700 mA.

(9) 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

[19] shows the typical voltage / current curve. Curve [20] shows

the voltage / current response to dynamic 50 ms load. Curve

load. Curve [22] shows the overload / temperature limit. To

1,2 - 1,5 Nm / 20,5 lb. in.

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. Nr. 896014. When using

a battery back-up, it is advisable to connect each power supply

to the battery positive terminal through it's own 50 A fuse. Units

should only be used in parallel where the supply exceed 3 x 370

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

= I

bat

max

setting and press the green "RESTART" button.

(13) Setting the LVR-voltage

The LVR-voltage is factory set to 20,5 VDC. It can be readjusted

with the potentiometer LVR-ADJ [26]. DIP-switches [8] must be

set 1 and 3 OFF, 2 and 4 ON. Release / return hysteresis is

about 4 VDC. Turn the LVR-ADJ-potentiometer fully counter

clockwise (25 turns). Adjust with the U-ADJ [6] potentiometer

the wanted release voltage on the output. Turn the

LVR-ADJ-potentiometer slowly clockwise until the supply

switches off and the red LED is turned on. Turn the

U-ADJ-potentiometer about 6 turns clockwise and restart the

supply with the green RESTART-button. Adjust the correct float

charge voltage on the output. The float charge voltage must be

4,5 VDC or greater as the LVR-voltage and lower as 28 VDC.

Attention:The output voltage is in the range 19 - 22 VDC only

for adjustment the under voltage release.The power supply unit

is available starting from 22 VDC with its full achievement.

Adjusting the LVR voltage is to take place only in the wired

condition.

(14) 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.

(15) Using circuit breakers on the power supply output

(lead acid)

On short-circuit, the power supply will trip, for example, the

following ABB-STOTZ circuit breakers.:
