Fluke 5220A Transconductance Amplifier
Condition: Pre-Owned
The model 5220A is a transconductance amplifier designed to operate as either a stand alone unit or an extension of the Fluke 5100 Series Calibrator. Functionally, the 5220A operates as a precision ac / dc current source for calibrating current shunts and/ or current meters. As the name (transconductance amplifier) implies, the output current level is a function of an input control voltage. The input / output ratio is established at 1:1 so that a voltage input in the range of -20 to +20 volts will produce a proportional current output of -20 to +20 amperes. Input voltages may be either dc or ac levels depending on the output requirements. Bandwidth for ac operation is dc to 5 kHz.
