The Model 201 5R is a general purpose DC power source
designed to furnish, regulated voltage or current for
electronic and scientific laboratory instrumentation.
Using silicon semiconductor devices exclusively and such
field proven proprietary techniques as Ambitrol® and Heatran
, the power supply has a reliability and versatility not
normally available in equipment of this type.
The Ambitrol dual amplifier control system permits operation
of the Model 2015R as a constant voltage or constant current
source over its entire operating range with'automatic
electronic transfer to either mode at any predetermined
operating point. The supply is completely protected against
internal damage for any load condition and may be operated
continuously into a short circuit. Protection of the load is
assured by continuously adjustable current limiting in the
constant voltage made and continuously adjustable voltage
compliance in the constant current mode.
The Heatran technique of power transistor dissipation
control makes possible the transfer of up to 90$ of the
normal power dissipation of the series pass transistors into
external vitreous enamel resistors, reducing the junction
temperature of the transistors and lowering internal ambient
temperatures in the equipment.
The output voltage or current may also be controlled from a-
remote location by means of external fixed or variable
Compact and light, the power supply is self-contained in any
integral housing for laboratory bench use. Tapped rivnuts
are provided on the face of the unit for panel mounting in a
test console or in a relay rack. Accessory panel adapters
with a height of 8-3/4” are available for mounting one or
two units in a standard 19” relay rack.
