The T2008 power supply is designed to provide the DC supply requirements of the Tait
T2000 two way radios. It can be operated either with the radio sitting on top as a desk
top unit, or with the radio and power supply detached as two separate units. The bot-
tom case includes two screw recesses for wall mounting. The two way radio then can be
mounted in its cradle next to the supply, or operated away from it, e.g. on a desk top,
etc.
If the radio and the power supply are operated away from each other, an extension cable
for the DC supply would have to be used. To keep the voltage drop of this extension
cable reasonably low, the wiring should be of sufficient gauge to carry the required load.
It is recommended that a minimum wire size of 1.5mm is used.
The power supply requires a mains supply of 230V nominal 50Hz or 115V nominal
60Hz, as set out in Section 8.1.2.
If the power supply is run at a high duty cycle rate, high continuous output currents
and/or high mains input voltage, it will generate a considerable amount of heat. An
adequate flow of cooling air past the unit, particularly past the heatsink, is therefore
essential for reliable operation. Do not operate the power supply in a completely
enclosed cabinet.
 Do not touch the heatsink after prolonged heavy duty operation. Keep the
heatsink away from anything affected by heat (plastics, etc).
The microphone clip supplied with every power supply may be attached to the side of
the top cover with the supplied screws and spacer, which fits between the clip and
cover. The hook switch monitor wire should be connected as shown in the wiring dia-
gram.
