The Kepco ATE with programmable overvoltage protector is a precision stabilized power supply which can deliver either stabilized output voltage or current. The prevailing operating mode is indicated by LED mode indicators at the front panel. Operating mode crossover is automatic and may be monitored remotely by means of a flag signal, available at the rear programming connector. The power supply features "full range” output control by means of 10-turn, high resolution front panel potentiometers. A pair of front panei meters constantly monitor the output voltage and output current. This power supply has'a linear and fully dissipative NPN pass transistor section driven by high-gain, integrated circuit amplifiers. The output of the power supply is fully programmable. Ail necessary input terminals are provided on a programming connector at the rear of the chassis. Terminals are also provided ror remote error sensing, as well as for the connection of the output capacitor directly at the load. 1-5 The ATE power supply features user-selectable "slow" or "fast" operating modes. Slow mode operation is recommended for applications demanding a constant voltage source. Fast mode operation is best if the output voltage must change rapidly, either in response to an external programming signal or, if the ATE is used as a current stabilizer, as a reaction to changing load resistance.
