4.2. Primary Power Supply and Distribution
Primary power for the Ranger-X5 is a single-phase 120/208 VAC input from the sites Main input.
The end user is required to provide an external UPS and a service disconnect with an Emergency
Stop button to remove all power from the radar system and provide a Lock-out/Tag-out point for
maintenance.
See Figure 66 for a block diagram showing the Primary Power Distribution through the Radar
System. For a more detailed drawing of the Power Control & Distribution Assembly, see the
Schematics and Circuit Diagrams.
Site power wires directly into the Power Control & Distribution Assembly into the Control Cabinet.
Power and ground cables connect to Field Terminals. Input power routes to the MAINS Circuit
Breaker on the E-Stop Panel Assembly (see Figure 16). DC Power controls through the Pedestal
Power circuit breaker (CB2) on the E-Stop Panel Assembly.
AC power is removed from the Ranger-X5 by use of any of the Emergency Stop switches (TX Indicator
Control Panel or Pedestal Enclosure). AC power is reset through the E-Stop Reset button located on the
E-Stop Panel Assembly.
A 2kVA UPS is an integral part of the system. The UPS power divides into two segments – 1
and 2. Segment 1 feeds the “A-Input” on the Power Distribution Unit. Segment 2 feeds the “B-
Input” on the PDU. The 16-Port Ethernet Switch and the KVM Switch are not controlled by the
PDU.
The Power Distribution Unit (PDU) provides the operator with remote command and control of
the power within the Ranger-X5. The PDU controls all of the operational aspects of the
machinery within Ranger-X5 – transmit, receive, antenna motion.
The Ranger-X5 is a DC powered radar system. The DC Power Plate feeds power to the Servo
System (AZ and EL), the Transceiver Units, the IQ2 Receiver system, and the cooling systems.
The DC Power Plate is controlled by a Circuit Breaker (CB2) on the output of the AC power of
port B2 on the Power Distribution Unit. CB2 can be interrupted by activating either of the two
E-Stop buttons.
