Push Button Power Supply for Switchboard Lamp Photometer

摘要

The design of a push button power supply for switchboard lamp photometer systems output is described. The system was designed primarily for the photometer system but can be applied to other test procedures and equipment. The power features push button selection and vernier adjustment to give any one of eight dc output voltages accurate to better than + or - 0.5%. The supply is stable with both time and temperature and has a low ac ripple content. (Author)
