3.2.1 AC Input Circuit Breaker
The PS2000 supplies power to the PA2000 by converting single-phase 220/240 VAC
into 50 VDC. The PS2000 is protected by a 20 A, double-pole circuit breaker
located on the rear panel. This AC input circuit breaker must be in the “up”
position (as shown below) for operation.

9. Place the Local/Remote switch (see Illustration 3–2) in the Remote position
and, using an external remote control unit connected to the Remote I/O
connector or the on-board remote Raise/Lower buttons, adjust the PA2000 to
the maximum power set by the Local Power Adjust. (This prevents adjusting
to higher than permitted power levels.)
10. Verify that the following conditions are present as indicated by the PA2000’s
Digital Multimeter:
a. In Ref—Should read between 0.4 and 0.8 volts (0.5 nominal, dependent
upon power input level).
b. SWR—Should read 1.05 to 1.5.
c. ALC—Should read between 4.00 and 6.00 volts for 2.2 kW output (less
for lower output or danger conditions, i.e. high SWR).
d. Power Out—Should read 2.20 for 2.2 kW output.
e. PA Temp—Should read 35 to 50°C with ambient temperature of 25°C.
The remainder of this section describes the functions of the front and rear panel
indicators and switches of the PA2000 and PS2000.
