The PA-123-3/2-500 houses a field and De-Gauss power
supply specifically designed to drive the ET-127 shaker. It is a class
AB, air-cooled unit with a power output of 2,600 VA, and is made up of
three separate interconnected chassis. The flexible PA-123 modular design
allows this amplifier to be configured for use with other shakers.
The CP-123 Control Panel features a low noise preamplifier,
amplifier output voltage and current metering, adjustable output current
limiting, and complete interlock circuitry. The power and field supply
chassis houses input power transformers, power supply circuitry, the shaker
interface, shaker cooling blower power source, and field cooling interlock
circuitry. |
