The 23VA transformer has three independent, secondary windings, two of which provide the two isolated,
pulsed DC, controlled outputs for train operation. The third isolated output supplies the AC and DC Auxiliary
outputs for the operation of remote controlled points and other accessories.
Each separate output winding is protected by a polyswitch safety cut-out which will shut down the individual
outputs under overheating or short circuit conditions. The transformer is ultimately protected by an internal
thermal fuse which will destruct in an extreme overheating situation.
The controlled DC outputs have variable power control, providing compensation for varying loads and have a
maximum current capacity of 530mA each. The AC and DC auxiliary outputs share a maximum current capacity
of 300mA.
The scope of the HM 2000 Power Controller can be further increased by the addition of left-hand and right-
hand HM 2000+ DC Controllers which are powered by the main unit via the side mounted “D” connectors.
These must be purchased separately as required. In most normal applications, one each of the HM 2000+
DC Controllers can be added, with further additions dependent upon the total current demand of the individual
railway layout. When ordering HM 2000+ units, make sure you specify whether left-hand or right-hand units
are required.
See instructions for HM2000+ DC Controllers on page 4 of this leaflet.
WARNING – THIS APPLIANCE MUST BE EARTHED
The power supply cable supplied, is fitted with a 3 amp fused plug. If you need to replace the plug, cut the plug
from the cable and dispose of it carefully.
WARNING – SHOCK HAZARD. Never insert a cut off plug into a wall socket as electric shock can
occur.
As the colours of the wires in the mains lead of this appliance may not correspond with the coloured markings
identifying the terminals of your plug, proceed as follows:
• Connect the wire coloured green and yellow to the terminal of the plug which is marked with the letter E or
by the earth symbol, or coloured green or green and yellow.
• Connect the wire coloured blue to the terminal of the plug which is marked with the letter N, or coloured
black.
• Connect the wire coloured brown to the terminal which is marked with the letter L, or coloured red.
If it becomes necessary to replace the fuse, only use a 3 amp, BS1362 approved fuse, fitted in the correct fuse
carrier.
The plug should never be used without a fuse carrier of the correct type and colour being fitted. Replacement
fuse carriers can be obtained from Hornby Hobbies Limited or from Official Hornby Service Dealers.
HM 2000+ DC Controllers can only be used as “plug-in” additions to HM 2000 Power Controllers, from which
they take their power supply. The units are produced in left or right-hand versions and can only be connected to
their correct side of the main HM 2000 Power Controller unit. Connect by engaging the appropriate male and
female “D” connectors.
The HM 2000+ then provides another controlled DC output from its rear terminals.

R8013A right-hand
An additional HM 2000+ DC Controller connected to the main unit shares the same secondary winding as the
controlled channel on that side of the main unit to which it is connected.
Therefore HM 2000+ DC Controllers are not isolated from the main unit controlled output to which they are
connected.
In order that the available current is shared efficiently, HM 2000+ DC Controllers should be added to alternate
sides rather than all to the same side.
The “Safety Notes” on page 3 overleaf apply also to HM 2000+ DC Controllers.
