3 Channel Voltage-to-Voltage Signal Conditioner - #5340

The model 5340 is a signal conditioning circuit which accepts three input voltages and provides three output voltages each of which is proportional to the RMS value of the input waveform. In addition a 4th voltage output is provided which is proportional to the sum of the three individual outputs. The circuit also provides a regulated 5Vdc supply which is intended as a supply for digital panel meters used to display the output of the circuit.

The circuit is intended to be used to measure DC waveforms, sinusoidal waveforms or non-sinusoidal waveforms resulting from either phase-angle or zero–cross control. The output response due to a step change of the input is equivalent to an RC time constant of 4 seconds.

The circuit is 11.5 inches long by 3.2 inches wide and 1.9 inches deep and is intended to be mounted using the Snap-Trak provided with the circuit.
