Amplifier Research TC2000

The Amplifier Research TC2000 is a transconductance amplifier that delivers stable, controlled current output for precision testing and measurement in laboratory environments. It excels at semiconductor device characterization and component testing through logic or analogue control inputs. The TC2000 model is optimized for resistive loads with low temperature coefficient, while the TC2001 variant accommodates inductive loads including three-phase transformers. Both units support multiple firing modes: burst firing for analogue inputs and logic firing for digital control, with the TC2001 offering adjustable delayed firing angle on the first cycle.
