Operation and Installation

The power supply has the following requirements:
•
Voltage:
8 … 18 V DC
•
Power Consumption:
< 10W charging, < 3W operating charged,
< 150mW standby charged
As the BFI57 is designed to be useful as backup device for
glass cockpit equipped aircraft, the “off” state in reality is a
standby, which (depending onto configuration) even allows
charging of the internal battery.
To avoid that with a parked aircraft the standby power
consumption empties the aircraft battery, between the BFI57
and the aircraft battery (e.g. an Avionics Master) is
absolutely mandatory.
