Fluke 5215A Precision Power Amplifier

The Fluke 5215A Precision Power Amplifier is an ac coupled programmable inverting amplifier with a fixed gain of 100. Output level is specified to 1100V at up to 200 mA, with a typical upper limit of 1200V before automatically tripping into standby mode. 

The 5215A includes automatic-overload sensing and recovery. Upon sensing an excessive slew rate or frequency of the input signal, or a momentary output overload, output is returned to zero within 2 microseconds and held there for 6 milliseconds, or until the fault is corrected.  When steady overload, shorted output, or excessive input drive level is detected, the 5215A trips and locks into standby mode and displays a fault indicator.
