ABOUT GLOBAL SP E C I A LTIES
Thank-you for selecting a GLOBAL SPECIALTIES product. You won’t
be disappointed ! Because we’ve never strayed from our original
founders’ simple ideal, lower the high cost of electronic design and
testing. Over the years, we’ve offered you electronic testing and
prottyping equipment that was engineered for the processinal, but
economically priced. The “best for less”, never compromising quality
in order to give you, our customer, a real value.
We accomplish our goal by cutting the industry giants down to size.
Most test equipment comes with excess features that you don’t want,
but have to pay for anyway. We eliminate these high cost features,
lower the price, but not the performance. The result is smarter tools for
the value minded user.
We pioneered the breadboarding industry allowing you to create circuits
as fast as you can think. Our breadboards are constructed to last. We
use high impact plastic and nickel silver contacts, plus “Made in U.S.A.”
quality and an unconditional lifetime guarantee. Our logic probes offer
speeds and storage capabilities only equaled by the fastest
oscilloscopes. When it comes to frequency counters we offer you far
more performance for far less money. Handheld or benchtop, frequency
counters or universal counter-timers, whatever you application you
can count on us. Our complete family of bench-top instruments offers
you features and performance unequaled, dollar for dollar.
In our continual strive for the “best for less” we never lose sight of the
future. We are always searching for ways to improve our existing
products and design new products using the latest technology. We do
this by asking you, our customers, what your needs are, and what your
likes and dislikes are. Feel free to contact us by phone, mail or fax with
your comments. Tell us how we can put Global to work for you.

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.
