The Transmille EA3012A is a powerful linear transconductance amplifier designed exclusively for use with the Transmille 3000 series calibrators which provides a cost effective solution to calibrating high currents instruments.

Connecting to the 3000 series calibrator using the feature connector, the EA3012A extends the output current range to 100A DC / 75A AC. Higher currents are available by paralleling the EA3012A amplifiers as required to give the current output needed.

The use of linear technology throughout gives a very low noise output completely free from switching spikes. The latest in high power MOSFET design ensures reliable and stable operation even into inductive loads. Long term accuracy is assured by using precision foil resistors and a custom manufactured internal shunt.
