Description

Multipurpose AC/DC measurement amplifier with power output stage. Can also be used as precision power supply. With built-in bias voltage source which makes an external voltage supply unnecessary when. Virtually misoperation- proof due to shortcircuit proof output, thermal overload protection and LED indicators for voltage overdrive and exceeding the maximum output current.

Examples of applications:

  • Audiofrequency amplifier for weak AC signals driving low-impedance loudspeakers
  • D.C. measuring amplifier, e.g. in thermal radiation measurements
  • A.C. measuring amplifier, e.g. in induction measurements
  • Power amplifier for function generators
