High Voltage DC-DC (6-Day Power Supply)
Modular Regulated Power Supplies

Output ranges: 0-1,000 volts to 0-30,000 volts


Input Voltage: +21.6 to 32.0 Vdc.

Output Polarity: Positive output is standard. For negative output, change first letter of model number from P to N.

Regulation (constant voltage operation):
Load: ±0.05%
Line: ±0.05%

Regulation (constant current operation):
Load: ±0.1% plus 50 uA
Line: ±0.1%

Ripple: 0.05%, peak-to-peak.

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/°C = 0.02%/°C (Typical).

Ambient Operating Temperature: -10 to +60°C. No derating required.

Storage Temperature: -20 to +85°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). All other connections on pluggable terminal block.

Size and Weight:

Case   | Rough               |  Approx. 
Size   | Dimensions (inches) |  weight 
HD345      3.4 x 4.1 x 6.2        2 lb.

See Drawing for exact dimensions.

Mounting: Threaded mounting holes permit mounting to a chassis, cabinet wall or bracket, or they may be used on a test bench or tabletop. To mount from the power supply side of the mounting surface, use accessory Mounting Kit GB8 (see Accesssory Mounting Kits). To mount on a DIN rail, see Accesssory Mounting Kits.
