INTRODUCTION
POWER SUPPLY : MODEL1310
The 1310 Power Supply is a versatile triple-output unit which can
be used in both digital and analog circuit applications. It consists
of three independent power supplies: a foxed 5 volt supply rated at
1.0 amps maximum, and two variable 1.3 to 20 volt supplies each
rated at 250 milliamps maximum. The three digit display allows the
voltage of the variable supplies to be quickly and accurately set, and
current flow can be monitored with 1 milliamp resolution.
All three supplies are completely isolated from each other, and from
earth ground. A circuit or piece of equipment connected to any one
of the supplies may be floated to DC level different from the other
two supplies. In addition, any two - or all three - supplies may be
connected to the chassis and earth ground is provided. And, of
course, each supply is protected against short circuit and thermal
overloads.
The 1310 is an excellent general purpose power supply for
engineering lab applications, bread-boarding, and prototyping.
The triple-output voltages make it ideal for working with all
disciplines, from microcomputer components to op-amps. Priced
economically, the 1310 is the perfect choice for production lines,
service shops, hobbyists, and whenever a compact, reliable DC
power supply is needed.
