SECTION 1

GENERAL DESCRIPTION

DESCRIPTION

The Model 2005 is a precision DC power source designed to

supply an extremely stable 0 to 20 volt, 0 to 500 milliainpere 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 heusing 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.
