OUTPUT — 0 to 20 VDC, continuously adjustable, at 0 to 500 MA.

INPUT — 105 to 125 V, 50 to 440 Hz, 40 W max. (including oven heater).

CALIBRATION AND ACCURACY — Two dual, concentric, decade switches provide dial readout to four places with an accuracy of 0.1% ± 1 MV at outputs below 10 V. A 1-MV range, single-turn potentiometer permits interpolation of the last place. This potentiometer has a resolution of 10 uV. A toggle switch extends the range of the dial readout from 10 to 20 V, without affecting resolution or accuracy (five-place readout). An illuminated indicator identifies the range in operation.

REGULATION — Output voltage change less than 100 uV (at sense connection points) for line or load variations over the operating range.

RIPPLE AND NOISE — Less than 100 uV 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 uS to return to within 250 uV or 0.005% (whichever is greater) of the set voltage for a 10% to 100% step change in rated load; less than 40 uS to return with 100 uV.

OPERATING TEMPERATURE RANGE — 15 to 4 °C ambient; 0 to 60 °C ambient with reduced accuracy.

TEMPERATURE COEFFICIENT — DC output voltage change

less than 0.001% or 50 uV (whichever is greater) per

°C over the range of + 15 to +45 °C; less than 0.002%

or 100 uV (whichever is greater) per °C from 0 to + 15

°C and +45 to +60 °C.

STABILITY — Better than 0.001% + 100 MV/8 hrs.; better than 1 MV/wk (at constant ambient temperature, load and line voltage, after warmup).

OUTPUT TERMINALS — Three front-panel binding posts and rear-panel barrier block. Either positive or negative output terminal may be grounded.

METER — Front-panel volt-ammeter permits monitoring output voltage or current with an accuracy of ±2%.

REMOTE SENSING — Two terminals on rear-panel barrier block are provided for remote sensing of voltage at the load.

REMOTE PROGRAMMING — Rear terminals are provided for remote programming of the output voltage at 1000 ohms-per-volt. Accuracy of programming is better than 0.01% of value of resistance (including connecting leads).

CURRENT LIMITING — The output current can be limited to any value from 0 to 500 MA by a front-panel control. A push-button permits easy adjustment without the need for shorting the output terminals.
