AB  - A four channel data acquisition system has been designed for measurement of four parameters needed for safety and thermal testing and modeling in a voice coil driven loudspeaker: Voice coil temperature, RMS voltage drive, current, and true V x I power dissipated. These data are stored in Excel format for post-processing. Safety tests with alternating or direct current stimulation require the current versus time displays needed for pre testing to UL 1480 and ANSI/CEA-636 standards Rated at 32 amperes, and 125 volts, the instrument is suitable for voice coils rated up to 5000 Watts. A real time graphics display on a standard PC is implemented with a USB interface.
