General Description
The VR565 Linear Power Amplifier is a high quality, air-cooled, direct-coupled audio amplifier designed specifically for use with small 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. The VR565 amplifier features protection from both over current and over temperature insuring long term reliability. The amplifier has full interlock capabilities as well as peak voltage and RMS current bar graphs to monitor output. Two operational modes are incorporated into the design. This amplifier can be used as either a wide bank, highly damped voltage source, or as a high impedance current source. DC and AC coupled signals are provided. VR565 amplifiers are designed for standard 19" rack-mounted installation and require 100, 120, 220 or 240V 48-60 Hz power.
