Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular
application.
SECTION 1
Hazardous voltages may be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuit boards, test points, and output voltages also may be floating above
(below chassis ground.
1.1
The equipment used contains ESD sensitive ports. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.

LM 600W Series
M362161-01 Rev L
x
Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis.
Similarly, other power ground lines including those to application and maintenance equipment must be
grounded properly for both personnel and equipment safety.
Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.
In normal operation, the operator does not have access to hazardous voltages within the chassis. However,
depending on the user’s application configuration, HIGH VOLTAGES HAZARDOUS TO HUMAN SAFETY
may be normally generated on the output terminals. The customer/user must ensure that the output power
lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages
is eliminated.
Guard against risks of electrical shock during open cover checks by not touching any portion of the
electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses
during open cover checks to avoid personal injury by any sudden component failure.
Neither AMETEK Programmable Power Inc., San iego, California, USA, nor any of the subsidiary sales
organizations can accept any responsibility for personnel, material or inconsequential injury, loss or
damage that results from improper use of the equipment and accessories.

SECTION 1
GENERAL DESCRIPTION
1.1 Intro uction
The Sorensen LM Series of 600W power supplies comprise a family of general purpose
programmable supplies for rackmount and benchtop applications. The LM 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 LM 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 LE 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. LE 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.

M362161-01 Rev L

The outputs are isolated from the chassis GN . However, an internal I0MΩ bleeder
resistor is connected from output return (-) to chassis ground. This allows operation
with floating outputs, or with either the negative or positive terminal of the output
referenced to chassis ground.
Master/slave paralleling is possible to allow multiple units to be operated in parallel for
greater output current or power. The master unit has full control of the other slave units
in setting the output voltage, current, and OVP. Multiple units can be connected in
series for increased output voltage, within the 300V float limitation of the output
terminals.
Remote programming is available with the standard non–isolated analog interface.
Output voltage, current, and OVP are fully controlled with user selectable programming
voltage levels or resistance programming.
Analog output signals are also provided to monitor the output voltage and current. In
addition, a complement of digital input/output signals allows control and monitoring of
the operational state of the supply. Optional interfaces such as GPIB, RS-232, isolated
remote analog, and LXI
TM
Class C Ethernet Interface allow adaptation of the supplies to
a variety of applications.

Notes:
1
Warranted over a temperature range of 0–50 ° C, with remote sensing at output terminals.
2
C input voltage variation within the allowed range, with constant load and temperature.
3
For 0–100% load variation, with constant nominal C input voltage and temperature.
4
Maximum drift over 8 hours with constant line, load, temperature, after 30 min. warm–up.
5
Change in output per ° C change in ambient temperature, with constant line and load.
6
Line drop subtracts from the maximum available output voltage at full rated power.
