IMPORTANT SAFETY INSTRUCTIONS
Before applying power to the system, verify that your product is configured properly for your
application.
WARNING!
Hazardous voltages might be present when covers are removed. Qualified
personnel must use extreme caution when servicing this equipment.
Circuitry, test points, and output voltages might be floating with respect to
chassis ground. Do not touch electrical circuits and use appropriately rated
test equipment. A safety ground wire must be connected from the chassis to
the AC mains input when servicing this equipment.
WARNING!
This equipment contains ESD sensitive input/output connection ports.
When installing equipment, follow ESD safety procedures. Electrostatic
discharges might cause damage to the equipment.
Only qualified personnel, who understand and deal with attendant hazards in power supplies,
can perform installation and servicing.
Ensure that the AC mains input ground is connected properly to the chassis safety ground
connection. 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 mains input is de-energized prior to connecting or disconnecting any cable.
In normal operation from the front panel, the operator does not have access to hazardous
voltages within the chassis. However, depending on the application configuration, HIGH
VOLTAGES HAZARDOUS TO HUMAN SAFETY might be normally generated on the output
terminals. The user must ensure that the output power lines are labeled properly as to the safety
hazards and that any possibility for 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, or 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.

FCC NOTICE
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment.
This equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own
expense.

ABOUT THIS MANUAL AND REGULATORY COMPLIANCE
This manual has been written for the Asterion DC Series of power supplies, which have been
designed and certified to meet the Low Voltage, Electromagnetic Compatibility, and RoHS
Directives per the requirements of the European Community.
These models have been designed and tested to meet the Electromagnetic Compatibility
Directive 2014/30/EU, and the Low Voltage Directive 2014/35/EU. In addition, these models
have been found compliant with FCC 47 CFR Part 15, Subpart B, 107(b) Class A, 109(g) Class
A.
Since the Low Voltage Directive is to ensure the safety of the equipment operator, universal
graphic symbols have been used both on the unit itself and in this manual to warn the operator
of potentially hazardous situations (see Safety Instructions page).

OVERVIEW
1.1 General Description
The Sorensen Asterion line of DC power supplies by AMETEK Programmable Power
combines intelligence and flexibility to create an advanced platform of DC solutions.
This easy-to-configure design features sophisticated technology for delivering high
performance, programmable DC power. Its sleek design packs maximum power
density into a low-profile form factor; with an intuitive touch screen interface placing
that power at your fingertips. Centralized control and unparalleled modularity make
Asterion the most adaptable platform on the market. Its groundbreaking capabilities
set the standard for affordable, precision power supplies.
The Asterion DC Series is Digital Signal Processor (DSP) controlled and can
be operated from the intuitive, easy-to-use front panel touchscreen or the
Ethernet LXI, USB and RS232 standard control interfaces, as well as through
the optional GPIB or EtherCAT control interface.

The touchscreen function group icons include a Dashboard, Output Programming
Parameters, Measurements, Ramp and Triggers, Configuration, Control Interfaces,
and System Settings. Function selection and parameter entry can be achieved either
by direct selection from the touchscreen or by using the encoder selector button. The
control resolution is adjusted by a dynamic rate change algorithm that combines the
benefits of precise control over small parameter changes with quick sweeps through
the entire range.

1.2 Specifications
The following sections provide electrical, environmental, and physical specifications
for the Asterion DC Series power supplies.
Unless otherwise noted, the specifications are valid under the following conditions:
a. Ambient temperature of 25 5C, after a 30-minute warm-up, and at fixed AC
input line and load.
b. DC output into a resistive load.
c. Specifications values are valid from 5% of the full-scale value.
d. Stability is over an 8-hour period after a 30-minute warm up.
e. If remote sense is used then the output voltage accuracy, regulation and
stability specifications are valid at the point where the remote sense leads are
connected.
