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 microseconds 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.
