Power Supply Requirements
Operating Voltage: 11 to 30V DC (Dual Input)
Input Power (Rx typical): 35 Watts
Input Power (Tx typical): (See table below)
In high ambient temperature situations, the internal fans may operate, resulting in an increase of input power of up to 28
Watts.
Typical receive/standby input power is 35 Watts. The input power will vary in
transmit mode according to RF output power level.
The QB450 is supplied with a lock-in mating DC power connector which should be
installed with the locking screws done up tightly (0.5 - 0.6 Nm / 4.42 - 5.31 ftin ).
The radio is designed to limit damage if the voltage exceeds the operating voltage
or if reverse polarity is applied. The field replaceable internal fuse has a 12 Amp
rating.
Connect and secure the antenna, Ethernet and serial connectors BEFORE applying power to the unit. Lastly, before inserting the
power connector, re-check that the polarity and voltage is correct using a multimeter and check the power cable against the +/-
label printed on the rear panel of the radio.

NOTICE
HAZARD OF EQUIPMENT DAMAGE
The radio modem can be damaged if there is any potential difference between the
chassis-ground, RS232 signal ground, power (-) input, or antenna coaxial shield.
Before connecting any wiring, ensure all components are earthed to a common
ground point.
Failure to follow these instructions can result in equipment damage.
