10.2.3 Powering the IFL
Transmitter power requirement: 15VDC @ 270mA
Receiver power requirement: 15VDC @ 360mA.
The Standalone Transmitter/Receiver is powered by a user-
supplied external DC power supply.
The Rackmount Transmitters/Receivers are plugged into the
rackmount chassis. The chassis can accept and power up to six
units.
Note
At temperatures below -10
°
C, the Transmitter’s internal heater will
require an additional 120 mA. The Transmitter’s total power
requirement will then be 390 mA.
CAUTION
Ensure that there is a good airflow around the chassis
rackmount.
Note
By default the power supply is set to 230V (0.5A).
