TABLE 1. ELECTRICAL SPECIFICATIONS

Parameter

Value

Output 0 to 20 volts DC, continuously adjustable,

0 to 500 milliamperes

Input

105 to 125 volts, 50 to 440 Hz, 40 watts

(nominal)

Regulation DC voltage change less than 100 microvolts for

line variations of ±10% or load variations

of 100% (at sense lead connection points)

Ripple and Noise

Less than 100 microvolts peak-to-peak

Source Impedance Less than 0.2 milliohm at DC, 0.04 ohm at

20 KHz, 0.5 ohm at 1 MHz

Recovery Time

Less than 10 microseconds to return to within

250 microvolts or 0.005% (whichever is greater)

of the set voltage for a step change in

rated load (1 microsecond rise time) of 10%

to 100% or 100% to 10%; less than 40 micro-

seconds to return to within 100 microvolts

Stability

Better than 0.001% +100 microvolts per 8 hours;

better than 1 millivolt per week (at constant

line, load and ambient temperature after

warm-up).

Temperature

DC output voltage change less than 0.001% or

Coefficient

50 microvolts (whichever is gr8ater) per

°C

over the range of +15 °C to +45 °C, less

than

0.002% or 100 microvolts (whichever is

greater) per0 °C from °C from 0 °C to +15

°C

and from +45 °C to +60 °C

Calibration Accuracy

Better than 0.1% +1 millivolt

Current Limiting 0 to 500 milliamperes continuously adjustable

by a front panel control. A front panel

push button permits easy adjustment without

shorting the output terminals.

Output Terminals

Front Panel

Three insulated binding posts for positive

output, negative output, and chassis ground

Rear Panel Screw terminals on a molded barrier block for

positive output, negative output, chassis

ground, remote voltage programming and remote

sensing.

Remote Sensing

Two terminals are provided on a rear panel

barrier block for remote sensing of the

voltage at the load.
