Input Voltage: 105-125 VAC, 50-400 Hz, single phase.
Output Polarity: Positive output.
Regulation (constant voltage operation): Load: +/- 0.05% Line: +/-0.05%
Regulation (constant current operation): Load: +/- 0.1% plus 50 uA. Line: +/- 0.1%
Output Controls: Voltage and current may be controlled by means of two 20-turn front panel adjustments,
or by using remotely located 1000 ohm potentiometers.
Output Programming: Output voltage and current may be programmed from 0 to full rating
by means of control voltage inputs of 0 to +5.1 Vdc.
Voltage Monitor Terminal: Permits monitoring output voltage, stepped down by ratio shown.
Accuracy is 2% of maximum rated output voltage.
Current Monitor Terminal: Permits monitoring output current at mV/mA ratio shown.
Accuracy is 2% of maximum rated output current.
Inhibit Terminal: Grounding inhibits output.
Input Protection: "Soft start" circuit minimizes start-up power stresses.
Output Protection: Current regulation circuit protects power supply from short circuits, overload and arcing.
Efficiency: Greater than 70% at full load.
Response Time: Less than 5 mS for 100 uA load step change.
Stability: 0.05% over eight hours, after 30 minute warmup.
Temperature Coefficient: 200 PPM/deg. C = 0.02%/deg.C (Typical).
Ambient Operating Temperature: -10 to +60 deg. C. No derating required.
Storage Temperature: -20 to +85 deg. C.
Humidity: Maximum of 90% relative, non-condensing.
Connections: 24" flying lead for high side of output and 5-way binding post for return (ground) are at the rear.
AC input connections on separate terminal strip. All other connections on pluggable terminal block.
