The Chroma 63640-80-80 DC load module provides three operating current ranges and a built-in 16-bit, precision A/D converter, achieving 0.025%+0.01%F.S., 0.05%+0.05%F.S. and 0.1%+0.1%F.S. accuracy for voltage, current and power measurement respectively. Real time measurement of voltage and current are integrated into each Chroma 63640-80-80 load module. The Chroma 63640-80-80 offers high speed, programmable dynamic loading, sweep simulation and control capability never before achieved. When the need is for increased power, paralleling two or more loads can be done to achieve the desired load current. Using several loads in parallel to emulate a single load dramatically simplifies operation and allows them to be used for both multiple output power supplies and larger single output supplies.
