PA-123-2/2-65 and PA-123-1/2-40
- Output: 65V, 2,000 VA
- Output: 40V, 750 VA
- DC/Direct-coupled linear output
- Adjustable current limiter
- Full external interlock circuit
 

The PA-123-X/2 amplifiers utilize standard PA-123 output modules and a CP-123 control panel/preamplifier. The number of output modules and power supply voltage is varied to match the load requirements. The PA-123-2/2-65 uses two output modules and full supply voltage. The PA-123-1/2-40 uses one output module and reduced supply voltage to match low impedance loads. The 2/2-65 can be configured to supply up to 130 Volts/18 Amps if required for high voltage loads.

A single chassis houses both the power supply as well as the output module(s) and is designed to mount in a standard 19” rack panel.
