IMPORTANT SAFETY INSTRUCTIONS
M362000-01 Rev E ix
Before applying power to the system, verify that your product is configured properly for your particular
application.
WARNING
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.
WARNING
The equipment used contains ESD sensitive parts. 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.
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 Diego, 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.

ABOUT THIS MANUAL
This manual has been written expressly for AMETEK’s Sorensen brand DLM–E 3kW and 4kW series of
power supplies, which have been designed to meet the 1997 Low Voltage and Electromagnetic Compatibility
Directive Requirements of the European Community, except DLM16-185E and DLM22-180E models.
These models have been designed and tested to meet the Electromagnetic Compatibility directive
(European Council directive 2004/108/EC, generally referred to as the EMC directive) and to the
requirements of the Low Voltage directive (European Councel directive 2006/95/EC, 93/68/EEC, dated 22
July 1993). In addition, these models have been found to be compliant with FCC 47 CFR Part 15, Subpart B,
107(e) Class A, 109(g) Class A.
Since the goal of the Low Voltage Directive is to ensure the safety of the equipment operator, universal
graphic symbols (see Safety Notice above) have been used both on the unit itself and in this manual to warn
the operator of potentially hazardous situations.

SECTION 1
FEATURES AND
SPECIFICATIONS
1.1 Description
The DLM–E Series 3000 and 4000 watt power supplies are designed to provide highly stable,
continuously variable output voltage and current for a broad range of development, system and
burn–in applications. Model numbers for this series are designated by the DLM prefix, followed
by the output voltage and current ratings. For example, the model number DLM40–100E
indicates that the unit is rated at 0–40 VDC and 0–100 amps while a model DLM8–350E is rated
at 0–8 VDC and 0–350 amps. The DLM–E Series employs high frequency switching regulator
technology to achieve high power density and small package size.
1.2 Operating Modes
The DLM–E Series supply has two basic operating modes: Constant Voltage and Constant
Current. In constant voltage mode, the output voltage is regulated at the selected value while
the output current varies with the load requirements. In constant current mode, the output
current is regulated at the selected value while output the voltage varies with the load
requirements.
An automatic crossover system enables the unit to switch operating modes in response to
varying load requirements. If, for example, the unit is operating in voltage mode and the load
current attempts to increase above the setting of the current control, the unit will switch
automatically from voltage mode to current mode. If the load current is subsequently reduced
below the setting of the current control the unit will return to voltage mode automatically.
1.3 Power Supply Features
•3 kW and 4 kW models with voltage ranges from 0–5 VDC to 0–600 VDC and
current ranges from 0–5A to 0–450A.
•3 kW models operate with either single or three–phase AC input power without
jumpers.
•High input AC power factor, 0.95 typical, with three–phase 208, 400, or 480 VAC
inputs.
