Input Signals
Input Power
The ACP53-001 requires a conditioned Input Voltage supplied by an external
communications management unit such as the AMU50:
Nominal: 25.5
Vdc
Maximum Current: 0.25 A @ 25.5 Vdc
Night Mode Input
Activation of the Night Mode input places the ACP53 integral lighting into Night Mode. In
this state the lighting is dimmed to be suitable for viewing at night. The ACP53 remains in
Night Mode for at least 50 ms after the Night Mode input is deactivated.
Quantity: one
Logic:
active LO, switched ground with no external pull up
Input Active: ≤3 Vdc
Current Draw: ≤100 mA
Input Protection: diode protected to +45 Vdc maximum
NVG Mode Input
Activation of the NVG Mode input places the ACP53 integral lighting into NVG Mode. In
this state the lighting is dimmed to be suitable for NVG viewing. The ACP53 remains in
NVG Mode for at least 50 ms after the NVG Mode input is deactivated.
Quantity: one
Logic:
active LO, switched ground with no external pull up
Input Active: ≤3 Vdc
Current Draw: ≤100 mA
Input Protection: diode protected to +45 Vdc maximum
Lights
Quantity two mutually exclusive panel lighting power inputs
Standard Panel Lights: 27.5 Vdc
Maximum Current:
0.10 A @ 27.5 Vdc
Optional Panel Lights: 5 Vdc
Maximum Current:
0.10 A @ 5 Vdc
RX Mute Input
While the RX (Receive) Mute Input is active, tthe ACP53 sets the Receiver Volumes and the
Transceiver Volumes,
except for the Transceiver selected by the Transmit Select switch, to
their minimum value.
Quantity: one
Logic:
active LO, switched ground, no external pull up
Input Active: ≤3 Vdc
Current Draw: ≤100 mA
Input Protection: diode protected to +45 Vdc maximum
