1.4 TECHNICAL INFORMATION
1.4.1 Power Requirements
The Universal II will operate from either 12 or 24 volt DC power with no customer changes necessary, although Monitors and Turrets
must be ordered as 12 or 24 volt for their proper operation. While the Universal II can operate below 10 volts, for optimum
performance, a minimum of 11 volts (for 12 volt monitors/turrets, 22 volts for 24 volt monitors/turrets) is required at the Universal II
J1 connector. The DC power is internally protected with a 30 amp non-serviceable fuse. This fuse is strictly for wiring protection and
should never need replacement under normal conditions. It is recommended that an external 20 amp slow blow fuse be placed in
series with the vehicle battery positive lead. The DC power for the Universal II is supplied through a 29 pin Deutsch connector (J1).
The DC power connects to pins 1 and 2, and they accept up to 12 AWG wire. See section 2.4.3 for pin-out information and schemat-
ics and section 2.5 for wiring connection detail. The electronic system has built-in reverse polarity protection. Long runs of cable
can introduce voltage/power loss. For long runs, it may be necessary to add an intermediate junction box fed by 10 AWG or heavier
wiring with a short 12 AWG run applied to the Universal II. If you need assistance in assessing wiring needs associated with long wir-
ing runs, contact Akron Brass technical support.
