Atec PRO-T User Manual

10 kW Programmable
Power Supplies

he PRO-T Series 10 kW program-

T

mable power supplies meet the
sophisticated control and packaging
requirements of high power test and
measurement applications. These
supplies have SCR preregulation.
Optional internal IEEE-488/RS 232
capability for various programming
and readback functions with 12-bit
resolution and accuracy is available.
Other features include outputs for
remote voltage and current readings,

Features

remote OVP programming and remote
shutdown. The PRO-T Series yields
80% efficiencies at full power with good

regulation (<0.1%) and RMS ripple as
low as 20 mV.

♦ Voltage

8 models from 0-16 to 0-600 VDC
and 16 to 625 ADC,

♦ Input

480 VAC, 50/60 Hz, three phase
input (optional inputs available)

♦ SCR Preregulator Topology

♦ Protection and Safety

• Unique circuit prevents load
burn-out should remote
programming lines open

• OVP shutdown standard

• SCR crowbar (Option M5)

♦ Remote Programming

• Remote control functions: voltage,
current, OVP shutdown, external
meter/indicator driver

• No programming resistors in
contact with output, avoids high
voltage problems with
programming components

• Optional Internal IEEE-488/RS 232
Interface Card with voltage and
current readback and adjustable
OVP (Option M9C)

♦ Regulation

0.1% line and load regulation (max.)

♦ Programming

Fast programming speed
(100 to 150 ms typical)

♦ Rear Panel Controls

Rear panel connector features: AC
control, shutdown, voltage set, OVP
set, local/remote current meter,
remote voltage meter, OVP
indication, thermal indication and
remote sense.

♦ Software

LabVIEW® driver for M9C/M85 can
be downloaded at no cost at
www.sorensen.com/support/
downloads.cfm

♦ CE Mark

(Option M36)

♦ 5 Year Warranty
