B. ACDIS1 AC & DC DISTRIBUTION
The ACDIS1 is the primary AC power inlet module. The UTX1KW-A transmitter was designed to accept
208 to 240 V AC using a four (4) wire connection. The four wires are:
• 2 wires for 208-240 V AC
• 1 wire for neutral connection
• 1 wire for safety ground connection
CAUTION:
Connection to the AC Primary Source must be made using all four wires listed above.
Follow the wiring instruction given in the AC WIRING section III.3 (Page 5). If not followed, severe
damage to the transmitter and or electrical shock is possible.
The ACDIS1 performs the following functions:
1. Provides a primary AC power breaker point to shutdown the transmitter.
2. Provides 220 VAC power to the each of the 2 KW DC power supplies with individual breaker
points for added safety.
3. Provides 110 VAC circuits for Modulator, ADP1000, ABS (auxilary power source for remote
control), and AUX Power where needed.
4. Analog metering is provided to monitor the Power Supply voltage and current being applied to
the RF Amplifi er stages
5. Power supply current sharing test points are provided for checking current sharing between Power
Supply modules.
SEE SECTION VI.B (Page 16) FOR SCHEMATIC AND PARTS LIST
C. RR6000 POWER SUPPLY
The UTX1KW-A transmitter is designed with over 4 KW of DC power available to the transmitter. To
achieve this level, the power supply is made up of two RR6000 power modules mounted into a main frame
assembly which is capable of managing three 2 KW modules. This transmitter can be ordered with a
spare supply module included in the unused port for a backup.
The power modules are “HOT PLUGGABLE” or can be removed and installed without turning off the
transmitter. If the third module is installed, removing a module will not affect the performance of the
transmitter.
Each power supply modules has OVER VOLTAGE, OVER CURRENT, AND OVER TEMPERATURE
protection as well as a fault signal in the event of a failure.
REFER TO MANUFACTURER’S MANUAL PROVIDED WITH THE UTX1KW-A.
D. ADP1000 PERFORMANCE MONITOR
The ADP1000 (PERFORMANCE MONITOR) provides the following functions:
1. Monitors FORWARD AND REFLECTED POWER to the antenna and presents it as a percentage
of power rating. The transmitter comes set to 100% P-Sync power based on the ratings of the
transmitter.
