|Description||Precision DC Power Source|
The Model 2005 is a precision DC power source designed to supply an extremely stable 0 to 20 volt, 0 to 500 milliampere output. The instrument combines the accuracy of a precision calibrator with the power capability of a general-purpose regulated supply. Two dual, concentric decade switches provide a digital readout of the selected output voltage to within 0.1% +1 millivolt of the selected value. A 1-millivolt range, single-turn potentiometer permits interpolation of the last place. This potentiometer has a resolution of 10 microvolts. A toggle switch selects the range of the dial readout; either from 0 to 10 volts, or from 10 to 20 volts. The output voltage of the supply may be remotely programmed with the same accuracy, using an external resistance. The supply also includes provisions for remote sensing of the output voltage at the load. Compact and light, the power source is self-contained in a portable housing designed for bench use. The modular construction of the Model 2005 makes it suitable for rack mounting. Panel adapters are available for mounting one or two units in a standard 19-inch rack having a panel height of 5 1/4 inches. • Calibrated decade voltage readout to four significant figures at outputs below 10 volts, to five significant figures above 10 volts. Interpolation of the last place is provided by a potentiometer with 10-microvolts resolution. • Provisions for rear-panel zero calibration (may be used to offset lead drop during remote sensing). • Adjustable current limiting. Description • Self-restoring electronic overload and short-circuit protection. • All silicon-semiconductor regulator system. • Critical semiconductors and components maintained at constant ambient in temperature-controlled oven. • Accurate remote programming at 1000 ohms-per.volt. • Front and rear access to output terminals. • 100 hour pre-aging of power supply before test and calibration. Individual calibration data furnished with each unit. • Line and load circuits separately fused. Accessible at rear. Performance specifications based on anticipated ratings after 5 years service. • "Controlled-Parameter" semiconductor program insures long life expectancy. Features "controlled avalanche" silicon rectifiers and power transistors, pre-aged zener voltage references and transistors, noise-testing techniques for establishing predictable device reliability, derating to 50% of rated voltage and current, etc. • Modular package construction suitable for rack mounting. Single or dual mounting in 5%"x 19" panel. See Cat. RPA-62 for rack panel adapters.
