Autoranging power provides versatility in dc apps

摘要

With rack space at a premium and constant pressures to drive the cost of test down, having the ability to produce a wide range of voltages and currents with one system power supply instead of several is very beneficial. A programmable dc power supply output shows the borders of an area containing all valid voltage and current combinations for mat particular output. Dc power supply output characteristics primarily fall into one of two categories: rectangular and au-toranging. With the more typical rectangular output characteristic, maximum power is produced at a single point coincident with the maximum voltage and maximum current values.
