The Model 5015T is a stable DC power source designed for laboratory, industrial, and eleetronic-system applications. Coarse and fine controls provide continuous adjustment over the entire output voltage range. A self-indicating current limiter permits output current control from zero to the maximum supply capability. Internal circuitry completely protects the instrument from overloads and short circuits. Rear terminals are provided for external voltage programming and remote sensing. Design simplicity results in a portable instrument with high reliability under severe service conditions. DESIGN FEATURES • Continuously adjustable output voltage with coarse and fine controls; resolution of 10 MV. • Continuously adjustable current limiting. • Remote sensing. • Remote programming. • Automatic dissipation-limit control of internal power transistors. • Series or parallel operation. • Front and rear output terminals. • All silicon semiconductors. e Modular construction permits multiple-unit rack mounting. As many as three supplies may be mounted in a standard 83/4" x 19" rack. (See catalog sheet RPA-62 for rack-panel adapters.) • Processed under Power Designs' "Predictable-Rellability" program for a 5-year MTBF. The program features: avalanche-controlled silicon rectifiers, stress-tested transistors, preaged zener references with extrapolated stability criteria based on Vf noise changes, computer- grade capacitors, tinoxidefilm resistors, and components operated at 50% of manufacturers' published ratings. Units preaged under fuil-load conditions for a minimum of 50 hours.
