3 Channel Current-to-Voltage Signal Conditioner - #5330
The Control Concepts' model 5330 is a signal conditioning circuit which accepts three input currents 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 model 5330 may be used to monitor the current applied to a three-phase load.
The circuit is 9 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.
