AMETEK Extends Industry Leading Sorensen SG Series of High-Power DC Supplies

SAN DIEGO, April 6, 2011 - AMETEK Programmable Power has expanded its Sorensen SG Series of
programmable precision high-power DC power supplies
(www.sorensen.com/go/sg/index.htm ) with four new output voltage
offerings of 10Vdc, 15Vdc, 20Vdc and 30Vdc to add to its current range of
40Vdc to 800Vdc. These lower voltage units have output power specifications
ranging from 4kW to 15kW. The 20Vdc model, for example, can supply up to 750
A in the standard 3U package, while the 10Vdc, 12kW unit can deliver up to
1,200A in the same 3U form factor.

Other industry-leading features of the expanded output voltages of
Sorensen SG Series include:

    - Industry leading voltage and current slew rates, both up and down
      programming
    - Improved power factor correction (PFC), with 3-phase 208, 400 and
      440/480 Vac input with the standard unit supporting both 50/60 Hz and
      400 Hz AC input frequency

The SG Series is one of the most popular DC power supplies
(www.sorensen.com/go/sg/index.htm ) on the market with more than
10,000 units in the field. The SG Series already leads the industry in power
density, delivering up to 15kW in just 3U. Depending on the output voltage,
one to six modules can be configured in a single chassis to deliver 5kW to
30kW of power; these can easily be paralleled to achieve up to 150kW of total
power.

All of the models in the SG Series are available with either Sorensen
General-purpose Intelligent (SGI) control or Sorensen General-purpose Analog
(SGA) control.

Units with SGI control combine onboard intelligent controls with the
outstanding power electronics common to all SG Series supplies. These
controls enable sophisticated sequencing, constant power mode and save/recall
of common setups, making the SGI ideal for repetitive testing using complex
or compliance waveforms. An impressive vacuum fluorescent graphical display
in eight languages, context sensitive "soft" keys and front panel keyboard
simplify programming of the SGI.

Units with SGA control are designed for users who require simple front
panel analog controls or remote analog control. With the same high
performance power electronics as the SGI, the SGA provides essential features
like 10- turn potentiometers for setting voltage and current, 3-1/2 digit LED
readout plus front panel OVP preview/adjustment and reset.

Units with SGI control come with standard analog control and an RS-232C
port. GPIB/IEEE 488.2 and LXI Ethernet ports are optional. Units with SGA
control come standard with remote analog control and can be fitted with an
RS-232C port, a GPIB/IEEE 488.2, and an LXI Ethernet port as optional
features.

Availability

Depending on output voltage, delivery is 4-8 weeks.
