| DC OUTPUT |
Voltage and current output can be adjusted over the range
indicated by front-panel controls or analog programming.
0-20 volts, 0-2 amperes
20-40 volts, 0-1 amperes |
| Model features automatic dual-range operation,
which eliminates manual range switching. |
| Load Effect |
constant-voltage deviation, 0.0005% + 100
µV.
Constant-current deviation, 0.01% +500µA. |
| Source Effect |
Over the rated input voltage range: constant-voltage,
0.0005% + 100µV; constant-current, 0.005%
+40 µA. |
| PARD (ripple and noise) |
rms/p-p, 20 Hz to 20 MHz; CV 40
µV/200
µV, CC 200 µA/1 mA. |
| Temperature Coefficient |
CV, 0.0001% + 15 µV/°C; CC,
0.02% + 50 µA/°C. |
| Drift |
CV, 0.0015% + 15µV per 8
hours, 0.0075% + 30 µV per 90 days. |
| Output Voltage Accuracy |
Output voltage accuracy
obtained from front-panel controls at 23 ± 3°C at any ac line voltage
and load current within rating and following a five-minute warm-up: 0.025%
+ 1.0 mV. |
| Resolution |
Front-panel voltage control,
200 µV; front-panel current control, 2 mA. |
| Output Impedance |
Typical value is approximated
by 0.05 mΩ
in series with 3 mH. |
| Load Transient Recovery time |
Less than 50 µS is required
for output voltage (constant voltage operation) to recover within 50 mV of
the nominal output level following a change in output current equal to the
current rating of the supply. |
| Remote Programming Speed |
Up programming of voltage at
full load: 1.75 s. Down programming, no load: 350 ms. |
| Overvoltage Protection Crowbar |
Adjustable front-panel
screwdriver control from 0.5 to 45 volts. |
| Power |
104-127 or 208-254 Vac
(switchable), 48-440 Hz, 150 VA max. |
