|Description||CALIBRATED PRECISION POWER SOURCE 0-20 VDC 0-500|
The Model 2005A is a calibrated precision power source designed to supply extremely stable DC out- put with low noise content. It represents a second generation version of the Model 2005, and is the product of six years of field experience with over 10,000 instruments. Performance and reliability have been significantly improved without any cost increase. Two dual, concentric decade switches provide digital readout of a selected output voltage to within 0.1 % of the chosen value. A single-turn potentiometer with a resolution of 10 microvolts permits interpolation of the last place. A toggle switch provides an additional digit in the 10to 20 volt range. The output voltage of the supply may be remotely programmed with an external resistance without loss of accuracy. Provisions are included for remote sensing of the output voltage at the load. Compact and light, the Model 2005A is self-contained in a portable housing designed for bench use, Panel adapters are available for assembling one or two units in a standard 19-inch rack. SERIAL NO:. DESIGN FEATURES ® Decade voltage readout to five significant figures below 10 volts; to six significant figures above 10 volts. Last-place interpolation by a potentiometer with a 1 millivolt range. • Current limiting—maximum output may be limited to any value below 500 mA with a front panel control. • Limit indicator lamp on the front panel flashes when the output of the supply is in the current-limited region. • Self-restoring electronic overload and short-circuit protection. • Critical circuits and components maintained at constant ambient temperature in a temperature-con- trolled. RFI-free oven. •Accurate remote programming at 1,000 ohms-per- volt. ® Front and rear access output terminals. • Separately fused line and load circuits. • 100-hour pre-aging of power supply before test and calibration. • Individual calibration data furnished with each unit.
