Group: Power supply
                                    This regulated power source is designed to provide extremely
accurate and stable D.C. output with less than 100
microvolts of ripple and noise content.
Two dual concentric decade switches provide digital
presentation of a selected output voltage to four places. A
calibrated potentiometer permits interpolation to a fifth
digit (Model 2020B) and sixth digit {Models 5020 & C500).
The mode! 2020B includes a toggle switch for 10-20 volt
operation with no change in resolution. The calibration for
all models is 0.1% of the dial settings.
The output voltage of the supply may be remotely programmed
with an external resistance without loss of accuracy. Rear
terminals provide for remote sensing of the output voltage
at the load. Calibrated output is available through either
pane! mounted binding posts of a rear mounted terminal
strip. Metering is provided by means of a dual scale
edgewise meter. A function switch selects voltage or current
Current limiting is continuously adjustable by means of a
front pane! control. The “pull-to- set” switch permits
adjustments of the current limit point without shorting the
output terminals. A flashing panel lamp indicates an
overload or short condition.
The power supply is floating with respect to the chassis
permitting positive or negative polarity. The output may be
continuously shorted without damage to the power source.
Each power supply is “burned in” for 100 hours prior to test
and shipment with calibration data. The power source is
housed in a blue enamel cabinet. The front panel is brushed
aluminum with black nomenclature. A tilting bail assembly is
provided for ease of viewing. Panel adaptors are available
for mounting one or two units in a standard 19 inch rack.
