FEATURES

0 - 10,000 Volts o’- 10 ma

Adjustable Overcurrent Trip

Fluke Model 410B is an extremely well regulated, low noise instrument designed to meet the most

exacting high voltage IX power supply requirements. The design utilizes a high-gain, all-silicon-transistor amplifier coupled with a single 4-65 series pa?.3 tube to provide exceptionally low ripple and high stabllity. Conservative design and high reliability components ensure stable. maintenance-Iree service for extended periods of time.

The high voltage Sowce is developed by a voltage doubler utilizing a tapped-primary transformer,

high-voltage silicon-rectifier stacks and oilfilled filter cappacttors.

lated by the type 4-65 series pass tube. tube Is with greater than 130 db of DC gain resulting in

0. 001% regulation and less than 1 mv RMS ripple.

available at front and rear panels through MS3102A-

18-16S ConnectorB. Outpat polarity may be selected

by mwns of the front panel switch to provide either positive- or negative-grounded operation. A zero-

center pane1 meter monitors output voltage. The 410B is protected against overcurrent conditions

by a current-trip circuit factory set at 12 ma load current. The current-trip level may be internally adjusted to latch off the supply between 5 and 15 ma.

Design development included thorough testing under adverse ConditionS of temperature, humidity, altitude, shock and vibration to ensure reliable operation under severe environmental coaditions. Package design has provided for a sturdy mechanical structure utilizing flow-soldered, glass-epoxy printed circuit boards for component mouMng. Interlocks interrupt the high

voltage excitation when top or bottom covers PFO

removed. Side panels are tapped to provide for mounting with standard chassis slides or other rack mounting arrangements. Resilient rubber feet are also provided for bench top use.
