MC102A ICCP Power Supply


MC102A power supply can provide power for prepolarized microphones, accelerometers and other ICCP (Integrated Constant Current Power) compatible transducers. It has two channels input/output with BNC connector, and wide voltage power supply supports the use of various DC power supplies.

ICCP is a well-established standard which is widely used in the acoustic and vibration field to convert the high impedance signal of measurement microphones and piezoelectric transducers to a low impedance voltage output signal. The abbreviation ICCP stands for "Integrated Constant Current Power" and has many manufacturer specific names such as ICP® (Integrated Circuit Piezoelectric), CCLD, DeltaTron®, ISOTRON® and IEPE (Integrate Electronics Piezoelectric). MC102A is compatible with microphones and transducers using any of the above proprietary names.

MC102A has an all-aluminum housing, which can effectively shield the internal signal. The LED indicators display the power supply status and the input status of each channel (input open (sensor not connected), OK (sensor connected), and input shorted). Each channel has a 35Vp input and output protection circuit, which can protect sensors and data acquisition equipment.
