7.1.1.1 Component Interoperation:
Power for the system is provided via an external AC power source in the range of 90 to
254 volts or an external DC power source in the range of +26 to +32 VDC (+28 VDC
nominal). When operated from an AC source, the UAC-350 Power Supply is used. The
UAC-350 provides an isolated and regulated +28 VDC output to the power interface box
for distribution to the transceiver and power amplifier. When operated from a DC power
source, the power supply is not used, and +28 VDC is applied directly to the DC input on
the power interface or power filter box.
The UIB-100 Power Interface Box attaches directly to the rear of the URC-200 (V2) and
provides the mechanical connections to distribute +28 volts DC to the transceiver, as well
as to the power amplifier via a cable connection from the interface box to the power
amplifier DC input. The UIB-100 Power Interface Box does not filter the DC input from
the power supply or DC source before distribution to the transceiver or amplifier. If the
UFB-100 is used in place of the UIB-100, then filtered power is supplied to the
transceiver and unfiltered power is supplied to the power amplifier.
The heart of the Rack Mounted System is the URC-200 (V2) multimode transceiver. The
transceiver is a lightweight, tactical, Line-Of-Sight (LOS) transceiver that provides AM
or FM communication of nonsecure voice or data in the VHF or UHF bands. The user
