3.3.2 Pin Assignment Information
3.3.2.1 CONVERTER
INPUT
POWER:
AC Line input –
Pin B
– 115 VAC. Connect to the aircraft 115 VAC bus using a 30
Amp circuit breaker.
AC Neutral input – Pin E
– Connect to the aircraft 115VAC Return Bus.
3.3.2.2 CONVERTER
DC
OUTPUT:
The TC2000 DC Output is isolated from the incoming 115VAC and the inverter
chassis. This allows the TC2000 to provide 28V DC output independent and isolated
from other aircraft DC power sources if desired.
DC +28V Output
–
Pin C
– Positive 28 volt output from the converter. Use of one or
more circuit breakers is optional.
DC -28V Output
–
Pin D
– Negative 28 volt output from the converter. In typical
aircraft, the negative 28V is connected to the airframe. However with the TC2000
converter the 28V negative can be connected to an isolated return bus if it is
desirable to have a 28V DC bus independent and isolated from the aircraft DC bus.
Note: Use of a circuit breaker on the DC output is optional. For the full
output of 2000W, a single circuit breaker current of 75 Amp maximum is
recommended. If multiple branching circuits are connected to the output,
then the total rating of all circuit breakers should not exceed 75 Amps.
3.3.2.3
CONVERTER REMOTE ENABLE CONTROL: (see section 4.2.1)
Remote ENABLE (ON/OFF Control) – Pin A –
Connecting this pin to the converter
DC -28V Output turns-ON the 28V output of the Converter. If the Converter DC-28V
Output is connected to the airframe then a remote ENABLE switch only needs to
connect this pin to the airframe to turn ON the output of the converter. When
unconnected (output is OFF) this pin will have approximately 28 VDC present,
internally limited to a few milliamps. If the Converter is to be enabled at all times, pin
A is to be connected to pin D.
