Information
                                    General
Designed for either bench or rack use, the typical DCR-B
power supply provides
a highly regulated, precise dc output, adjustable over a
wide range.
It operates from a nominal 115 Vat (208/220/230 Vat inputs
are available as options)
and exhibits a rapid response to transients, both load and line.
DCR-B series supplies are phase controlled type with SCR’s
(Silicon Controlled
Rectifiers) or Triacs at the input to the transformer,
followed by a passive LC
filter. This design allows for a wide range of output
voltages, simplicity of
design, and offers large amounts of regulated power at
relatively high efficiencies
compared to linear regulators.
Silicon type semiconductors are used extensively in DCR-B
circuitry, and contribute
significantly, to the units’ wide ambient temperature range
characteristic.
Low dissipation transistors and diodes are located on a
single printed circuit
board while high dissipation devices are heat sinked to
aluminum brackets and
heatsinks.
All controls used during normal operation, except the OVP
control, are mounted
on the front panel. These include a power circuit breaker,
FINE and COARSE
VOLTAGE adjust potentiometers, and FINE and COARSE CURRENT
adjust potentiometers.
The system output is taken across a terminal pair at rear
terminal
strip TB2.
A variety of Sorensen power supply application notes are
available through your
Sorensen Service Representative. These notes detail many
hook-up configurations
and special usages available to meet most power supply
applications.
1.2.2 Automatic Crossover
There are two basic operating modes, voltage and current. In
the voltage mode,
the voltage is held constant while the current varies with
the load.

Information
This manual contains operation and maintenance data on the
1800 watt units of
the DCR-B series Sorensen Power Supplies. It is intended to
familiarize the
user with the functioning of the unit, to introduce the
varied applications to
which the unit may be adapted, and to furnish sufficient
maintenance data to
assure long operating life.
Six major sections form the manual divisions. Section 1
contains a brief functional
description of the DCR-B series power supplies. Initial
inspection and checkout
procedures are outlined in section 2. Operating
instructions, including methods
for adapting units to various applications, comprise section
3. Sections 4 and 5
provide the principles of operation and maintenance
procedures respectively.
System drawings and the replacement parts list are provided
in section 6.
