GENERAL DESCRIPTION
1.1 Introduction
The Sorensen DLM Series of 600W power supplies comprise a family of general purpose
programmable supplies for rackmount and benchtop applications. The DLM 600W series
consists of nine models, rated 5V/75A, 8V/75A, 10V/60A, 20V/30A, 40V/15A, 60V/10A,
80V/7.5A, 150V/4A, and 300V/2A.
A variety of user interfaces are available, ranging from manual front–panel control and
standard non–isolated remote analog control, to optional GPIB or isolated remote analog
control.
1.2 General Description
The DLM series power supplies incorporate the latest power conversion and control
technology to provide high accuracy, excellent regulation, low output noise, and fast
transient response. They utilize a switched–mode output power converter for high
efficiency and power density. The converter has been optimized to provide
performance approaching that of linear supplies. A high switching frequency combined
with Zero–Voltage Transition power switching and dual–stage output filtering account for
the excellent dynamic and noise characteristics. Precise regulation of output voltage or
current is possible with operation as either a voltage source in constant–voltage mode
(CV), or as current source in constant–current mode (CC). Crossover between modes
is automatic, dependent on load demand.
The front panel contains all controls and indicators required for setting and monitoring
the output parameters, as well as annunciation of operational status. Individual
adjustment controls are provided for output voltage, current, and over voltage protection
(OVP). Two 3.5 digit LED displays normally measure the output voltage and current. In
conjunction with the preview switches, these displays also show the programmed
values of voltage, current, or OVP. The preview functions allow adjustment of those
parameters without disturbing load connections. LED indicators show the mode of
operation (CV or CC), programming control source, or abnormal operating conditions.
Switches are also provided to directly control the output power, and to switch between
local and remote control.
