2. Electrical Installation
The Antenna Controller power requirements are 12Vac/dc@500mA.
This power supply, protected by a 0.5A fuse on the reader, does not include supply to
external outputs.
Maximum consumption, including supply to external outputs, is 1A
Power to the Antenna Controller can be supplied in three different ways:
a) 12Vac, rectified by a diode bridge on the reader.
B) 12Vac from a transformer with two 12Vac outputs and a center point,
Important note!
For this option the two negative polarity diodes of the diode bridge
rectifier
D29 and D30
(see
Figure 0-1
)
must be removed
.
c) 12 regulated/non regulated DC voltage.
