The ASD with DaVinci Power™ technology
represents the next generation of precision
programmable AC-DC power conversion.

The ASD with its 3U, 30kW water-cooled
packaging provides the highest power density
available. The ASD is designed for industry
leading load transient response with outstanding
output ripple and noise. The water-cooling
packaging allows for use in environments that
normally exclude air-cooled power supplies.

The ASD advanced digital architecture, with real­time digital control and Graphical User Interface
(GUI), enables many features to better control
and monitor your process or application. The
optional advanced features package includes a
built-in oscilloscope function for measurement
and display of: power, voltage, current, output
impedance, output cable impedance and
output cable voltage drop. The ASD allows you
to program different “fault levels”, enabling
detection of output cabling, connections or
load problems before they cause critical system
problems. The ASD can replace your PLC device
by closing the loop on an external parameter such
as temperature. The ASD’s Advanced Diagnostics
And Maintenance (ADAM
ight data recorder feature that lets you access
multiple recorded parameters, such as: voltage,
current, power, load impedance, faults and input
voltage. This allows you to easily determine
“why” you had an unexpected outcome.

The advanced digital monitoring and control
features combined with industry leading power
density and reliability makes the Sorensen ASD
the supply of choice for stringent and high value
processes and applications.

Advanced features include:

• Precise programming of voltage and current

slew rate for sensitive loads.

• Modules within one chassis can be connected

to different loads and controlled independently.

• Industrial eld bus interface (Modbus-TCP,

Modbus-RTU, Ethernet/IP (Industrial Protocol))
enable real-time digital control.

• Built-in energy meter calculates the delivered

energy throughout a process or period of time.

• Optional real time clock enables accurate

timestamping of events.

• Built in power quality monitoring detects and

saves input voltage anomalies which can be
saved for later diagnostic analysis.

• Programmable analog interface scaling

facilitates incorporating the ASD to existing
systems with minimal effort.

• Load impedance measurement, including

rate-of-change calculations, enable load “state
of health” monitoring and implementation of
system preventive maintenance algorithms

• Programmable lter bandwidth of the output

voltage, current and power monitors let the user
accommodate their response speed to particular
needs.

• Full featured GUI (Graphical User Interface)

helps to test and debug the system by
communicating with the power supply in
real time
