1.5:1 VSWR within foldback limits
Short Term stability: +/-1%/hr
Long term stability: +/-5% over three years continuous output
Zero Setpoint: less than 5 watts actual output power and less than 5 watts readback
power when setpoint signal is at zero or at a negative voltage.
NOTE:
Use RF enable switch (Pins 4-9) 15 Pin D to ensure zero output power.
B. Protection Features
1. Mismatch Protection: Continuous operation into any impedance mismatch condition
without damage or malfunction; forward power foldback shall occur within 500us if
reflected power exceeds 150 Watts.
2. Output power connection interlock: Hard-wired interlock that disables the input AC
power contactor upon removal of the output cable.
3. Safety interlock: Disables the input AC power contactor via the connector. MAX external
loop resistance of 5.0 ohms .
4. Over Temp Fault: Output disabled on high internal temperature
5. Short Circuit Fault: Output limiting protection under short and open circuit conditions.
6. Overdrive Limit: Internally limited at 1100 watts.
7. Control signal protection: Unit not to be damaged if a short circuit or up to 30 volts AC or
DC is placed between any input signal, return signal, and ground.
C. Generator I/O Requirements
1. Signal input impedance: 10K ohms, min.
2. Signal input isolation: 1000 VAC MIN to the A/C supply line.
3. Line connections: Linecord to be 14AWG 4 conductor (three phase & ground); linecord
jacket material to be type "STO" gray; linecord to be crimped to NEMA L15-20P style
plug; linecord length to be 4.5 ft. +/-6.0 inches as measured from the rear panel exterior to
the strain relief end of plug. Reference MARINCO part number 2015P-AM1.

4. RF Output power Connector: One type "N" female coaxial connector
5. Control connector: 15 pin subminiature "D" type, (female).
6. Control signals and pinout:
Pin 5: Power setpoint
0 to +10 VDC = 0 to 1.0 KW linear
Pin 3: Forward power out
0 to +10 VDC = 0 to 1.0 KW linear
Pin 2: Reflected power out
0 to +10 VDC = 0 to 1.0 KW linear
