Model 730 Power Supply for Gas Discharge Lamp
The Model 730 is a Power Supply for Hinteregger and Hollow Cathode Lamps. This supply is equipped with a ballast module to accommodate the gas discharge function of noble gas sources. When ordered with a source, the supply is equipped with all interconnecting cables, etc. to comprise a turn key system for stable operation of the noble gas sources.
Input: 105-125Vrms; 50-60Hz, single phase.
Output: 0 - 2000V. Continuous, stable adjustability from 0 to rated voltage and current. 10 turn front panel voltage and current controls with resolution and readability better than 500 PPM. Linear to 1 %. Control dial can be locked.
Voltage Regulation: Load, better than 0.005% for full load variation: line, better than 0.005% over specified input range.*
Current Regulation: 0 - 500 mA. Load, better than 100 micro amperes from short circuit to rated voltage at any load condition. Line, better than 0.005% over input range.*
Ripple: Better than 0.l% of rated voltage at full load. Ripple voltage is proportional to load current and decreases linearity to 0.02% rms of rated voltage at no load.
Stability: 0.01% per hour after hour warm-up. 0.05% per 8 hours.*
Temperature Coefficient: 0.01% / C.*
Ambient Temperature: -20C to +60C, operating; -40C to +85C storage.
Polarity: reversible high voltage with respect to Chassis ground. (separate HV modules have to be used for reversible polarity model.)
Protection: Automatic current regulation protects power supply against all overload conditions, including arcs and short circuits. Fuses, surge limiting resistors, and low energy components provide the ultimate protection. Primary contactor prevents automatic reset of power supply after line failure.
*For voltage range from 25% to 1 00% of rated output.
Line Cord: 6-foot, with standard 3-pin grounded plug.
Output: Receptacle for high voltage coaxial cable. 8-foot, shield, mating cable provided.
External Interlock Terminals: Output voltage is maintained at zero when external contact par "opens". External contact pair must be "closed" for normal operation.
Remote Voltage and Current Readout Terminals: Provides 0-10VDC full scale signal with 10 kilohm impedance.
Remote Voltage and Current Control: Three terminals for either potentiometer or "remote programming" voltage with respect to ground. Supply designed for rated output with + 10V input, with better than 1% control linearity from 10% to 100% of output. Supply protected against remote programming overvoltage up to 50V.
