Power requirements
Depending on your particular TT-3000 System you will need AC supply or a DC supply.
A TT-3000 Integrated Capsat System operates on either 115 VAC, 220 VAC or floating
DC in the range from 10.5-32 Volt. The total power consumption varies with the
particular system in question.
As a guide-line, please note the power consumption of the following equipment:
TT-1542B Call Alarm
0.6 W

AC mains operation
As the TT-3020B Capsat Transceiver is designed to work on floating DC ranging from
10.5 - 32 Volt, an AC/DC converter is needed in case the Transceiver is subject to work
in AC environments.
2.3.1.1
Integrated Capsat System
For a TT-3000 Integrated Capsat System with an IBM compatible PC we recommend the
TT-3680A Power Supply.
The TT-3680A Power Supply operates on either 115 VAC or 230 VAC. (internally
selectable) and supplies 24 VDC/96 Watt as a maximum.
The TT-3680A will adjust the DC output level (10.5 - 32 Volt) according to the total load.
The TT-3680A Power Supply may be connected to the emergency batteries offering
automatic switch-over to DC in case of a mains line drop-out.
For a TT-3000 Integrated Capsat System with a TT-3608A Message Terminal we
recommend the TT-3680B Power Supply.
