SECTION 1
Important Safety Instructions
Before applying power to the system, verify that your product is configured properly for your particular
application.
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.
Only qualified personnel who deal with attendant hazards in power supplies, are allowed to perform
installation and servicing.
M362500-01 Rev K
1.1
The equipment used contains ESD sensitive parts. When installing
equipment, follow ESD Safety Procedures. Electrostatic discharges might
cause damage to the equipment.
ix
Contents Sorensen DCS Series 1kW and 1.2kW Supplies
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.

SECTION 1
FEATURES AND SPECIFICATIONS
1.1 Description
DCS Series power supplies are 1000W and 1200W supplies designed to provide highly stable,
continuously variable output voltage and current for a broad range of development, system, and
burn-in applications. The DCS Series employs high frequency switching regulator technology to
achieve high power density and small package size.
The series consists of twelve 1000W models and twelve 1200W models. The model numbers
are designated by the DCS prefix, followed by the output voltage and current ratings. For
example, the model number DCS 60-18E indicates that the unit is rated at 0-60 Vdc and 0-18
Amps while a model DCS 20-50E is rated at 0-20 Vdc and 0-50 Amps.
1.2 Operating Modes
The DCS 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
•
Twelve 1kW models with voltage ranges from 0-8 Vdc to 0-600 Vdc and current
outputs from 1.7A to 125A.
•
Twelve 1.2kW models with voltage ranges from 0-8 Vdc to 0-600 Vdc and current
outputs from 2A to 140A.
•
115/230 Vac selectable input voltage, 50-60 Hz single phase,
Installation Category II. For Indoor Use.
•
Simultaneous digital display of both voltage and current.
