•

The instrument may only be connected to

the mains via a socket that has an earth

connection.

•

Before making any connections, check the

experiment leads for damaged insulation

and exposed wires.

•

Replace any blown fuses only with new

ones that match the specifications stated on

the rear of the housing

•

Disconnect the equipment from the mains

before replacing a fuse.

•

Never short the fuse or the fuse holder.

•

Never cover the air vents and heat sink at

the rear of the housing. These are neces-

sary in order to ensure sufficient circulation

of air required for cooling the components

inside the equipment.

•

The

equipment

opened/repaired by qualified and trained

personnel.

2. Description

The AC/DC power supply provides a continu-

ously adjustable, stabilised AC or DC voltage for

student exercises and experiments. Either AC or

DC output voltage is selected by means of a

toggle switch.

The power supply 1001006 is for operation with

a mains voltage of 115 V (±10%), and the unit

1001007 is for operation with a mains voltage of

230 V (±10%).

4. Operation

It is recommended to use one of the following

instruments to measure the output voltage:

Analogue Multimeter AM50

Analogue Multimeter AM51

Caution:

The AC and DC outputs cannot be used at the

same time.

Subject to technical amendments

4.1 Obtaining an AC voltage

•

Connect the unit to the mains supply. Turn

the voltage control knob fully to the left.

•

Connect the load to the AC output sockets.

•

Set the toggle switch to AC.

•

Press the mains switch; the mains indicator

light shows green.

•

Set the required voltage using the voltage

control; if necessary, connect a voltmeter in

parallel with the load.

4.2 Obtaining a DC voltage

•

Connect the unit to the mains supply. Turn

the voltage control knob fully to the left.

•

Connect the load to the DC output sockets.

•

Set the toggle switch to DC.

•

Press the mains switch; the mains indicator

light shows green.

•

Set the required voltage using the voltage

control; if necessary, connect a voltmeter in

parallel with the load.

4.3 Changing the fuse

•

Before changing the fuse, unplug the unit

from the mains.

•

Using a screwdriver (or similar tool), un-

screw and lift out the fuse holder.

•

Replace the fuse with a new one with the

same specifications.

•

Screw the fuse holder back into place.

5. Care and maintenance

•

Before cleaning the equipment, disconnect it

from its power supply.

•

Use a soft, damp cloth to clean it.

•

The packaging should be disposed of at

local recycling points.

•

Should you need to dispose of the equip-

ment itself, never throw it away in normal

domestic waste. Local regulations for the

disposal of electrical equipment will apply.
