GENERAL DESCRIPTION

The Labworks PA-141 Linear Power Amplifier is a high

quality, air-cooled, direct-coupled audio amplifier primarily

intended for use with vibration systems. Although this

amplifier has been designed to directly drive low impedance

loads, it can be used in any application requiring continuous

duty, high quality, audio power.

There are two operational modes. The amplifier can be

used as either a wide-band, highly damped voltage source,

or as a high impedance current source. DC and AC coupled

signal inputs are provided.

In order to insure long term reliability, the PA-141 features

protection from both over current and over temperature.

Full interlock circuitry is also included. Peak voltage and RMS

current bar graphs monitor output conditions.

Optional, internal DC field power supplies are available for

use in conjunction with Labworks Shakers. These options

provide the convenience of a single chassis power source,

as well as fully integrated power-up and cooling interlock

circuitry with the power amplifier. Switched 115 Vac power

is provided for shaker cooling blower and control instrument

requirements.

The PA-141 is designed for standard 19 in. rack mounted

installation and can be operated on 100, 120, 200, 220 or

240V, 48 to 62 Hz power.
