Power Designs Inc. 2015R Power supply
All Silicon Constant Voltage Current Power Suppl


The Model 201 5R is a general purpose DC power source designed to furnish, regulated voltage or current for electronic and scientific laboratory instrumentation. Using silicon semiconductor devices exclusively and such field proven proprietary techniques as Ambitrol® and Heatran , the Power supply has a reliability and versatility not normally available in equipment of this type. The Ambitrol dual Amplifier control system permits operation of the Model 2015R as a constant voltage or constant current source over its entire operating range with'automatic electronic transfer to either mode at any predetermined operating point. The supply is completely protected against internal damage for any load condition and may be operated continuously into a short circuit. Protection of the load is assured by continuously adjustable current limiting in the constant voltage made and continuously adjustable voltage compliance in the constant current mode. a The Heatran technique of power transistor dissipation control makes possible the transfer of up to 90$ of the normal power dissipation of the series pass transistors into external vitreous enamel resistors, reducing the junction temperature of the transistors and lowering internal ambient temperatures in the equipment. The output voltage or current may also be controlled from a- remote location by means of external fixed or variable resistors. Compact and light, the Power supply is self-contained in any integral housing for laboratory bench use. Tapped rivnuts are provided on the face of the unit for panel mounting in a test console or in a relay rack. Accessory panel adapters with a height of 8-3/4” are available for mounting one or two units in a standard 19” relay rack. * &'AMB!TRGt DuoS Amplifier control system permits continuous control of voHcge of current with automatic electronic crossover So either mode of operation. * ^HEATRAN Electron ic power frarssisfor dissipation control. * Performance specifications based on anticipated ratings at end of five years of service life. * New SHtcan power transistors assure high stability end provides major breakthrough ir< predictable reliability. * Pre-aged transistors with ‘‘reliabifify controlled" parameters for insured long life. ® ''Controlled Avalanche” Silicon rectifiers to prevent line transient failure*. * Builf-m circuitry eliminates the possibility of turn-ort and turnoff transients. * Oual concentric confrofs for coarse and fine voitage adjustment. * Front and rear occess output term me Is. * Silicon dtade voltage references with cornplemerstary temperature coefficients. * Semiconductor devices derated to 50 % of rated voltage and current. » Volt-ammeter monitors output voltage or current. ® Computer qualify electrolytic capacitors. * Line and food circuits separately fused.
