Common European honeybee. Managed in hives for at least 3,000 years, honeybees are the chief pollinating agent for 80% of the commercial cultivation of fruits, grains, and vegeta bles. Each hive consists of from 40,000 to 80,000 bees organized in a highly structured social order. Small, disciplined, adaptable, and highly productive, Series MK). Automatic crossover from constant voltage honeybees are one of the many wonders of nature. to constant current regulation protects both the sup ply and load from overload conditions, including arcs and short circuits. A safety interlock circuit is standard. So is remote programming and monitoring of both Classman Series MI and MK regulated DC high voltage voltage and current, in addition to local control. modules are little wonders in their own rights. Extremely small, lightweight, and compact, these effi cient power supplies are widely used in low power CRT applications, electrophoresis measurements, ion beam experiments, particle precipitation, X-ray, imaging, and other electrostatic applications. Available in a large number of models, the 15 watt Series MJ output ranges are 0 to 3 kV through 0 to 30 kV. The 7 5 watt Series MK has ranges from 0 to 1 kV through 0 to 60 kV. Both the Series MJ and MK feature air insulation of critical high voltage components. This results, not only in low weight, but in easy serviceability...avoiding the prob lems associated with encapsulated "throw-away” modules. Though small in size these modules are big in perform Call or write for more information on these versatile ance. Voltage regulation is better than 0.005% for line high voltage power supplies. You'll "wonder” why you and load variations. Ripple is less than 0.05% (0.03%, ever considered anything else! Innovations in high voltage power supply, technology. CLASSMAN HIGH VOLTAGE INC.
