The Fluke Model 408B High Voltage DC Power Supply is capable of providing an output of 0 to 6,000 Vdc at 0 to 20 mA. The output voltage is selected by four decade switches and a vernier potentiometer. The instrument may be operated with either positive or negative output terminal grounded, as selected by a front-panel switch. Overcurrent protection is provided to return the supply to standby operation in the event of excessive load current. The Model 408B is a hybrid design utilizing silicon transistors for the amplifier circuitry and a vacuum tube for the necessary high voltage series passing element. A time-delay relay is incorporated in the input circuitry, which prolongs the life of the high voltage passing tube. The reference element is a highly stable temperature compensated gas tube. SPECIFICATIONS Electrical OUTPUT VOLTAGE 0 to +/-6,000 VDC OUTPUT CURRENT 0 to 20 mA OUTPUT POLARITY + or - grounded via front panel switch LINE REGULATION 0.001% or 2 mV (whichever is greater) for 10% line change from nominal LOAD REGULATION 0.001% or 5 mV (whichever is greater) for full load change STABILITY +/-0.005% per hour; +/-0.02% per day after warmup RESOLUTION 5 mV RIPPLE Less than 1 mV RMS; less than 5 mv peak-to-peak VOLTAGE CALIBRATION 0 to 5000V in 5 steps of 1000V 0 to 900V in 9 steps of 100V 0 to 90V in 9 steps of 10V 0 to 9V in 9 steps of 1V 0 to 1. 2V vernier CALIBRATION ACCURACY +/-0.25% or 250 mV (which-ever is greater) with vernier at zero RESETABILITY +/-0.05% or 50 mV (whichever is greater) RECOVERY TIME Within 50 uSec WARMUP TIME 30 minutes OVERCURRENT TRIP Set to latch off at 25 mA load current. Internally adjustable from 5 to 25 mA METER 6000-0-6000 vdc (+/-3%) OUTPUT CONNECTORS MS3102A-18-16S front and rear (one mating connector supplied) INPUT POWER 100/115/230 VAC +/-10%, 50-5000 Hz, approx. 300 VA at full output MECHANICAL HUMIDITY 0 to 80% OPERATING TEMPERATURE RANGE 0' C to 50' C STORAGE TEMPERATURE RANGE -200' C to +70' C ALTITUDE, OPERATING 0 to 10,000 ft ALTITUDE, NON-OPERATING 0 to 50,000 ft VIBRATION Meets MIL-T-945A SHOCK Meets MIL-E-4970A (20 g's, 11 mSec in three principal axis) TEMPERATURE COEFFICIENT OF OUTPUT Less than 20 ppm per 'C from +10' C to +400' C SIZE 19" wide x 8-3/4" high x 15" behind panel (rack mount with resilient feet for bench use) WEIGHT Approximately 59 pounds
