AMETEK Extends Sorensen SG Series of High-Power DC Supplies

March 28, 2011 by Jeff Shepard

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

Other features of the expanded output voltages of Sorensen SG Series include: what the company says is industry leading voltage and current slew rates, both up and down programming; and improved power factor correction (PFC), with 3-phase 208, 400 and 440/480Vac input with the standard unit supporting both 50/60 Hz and 400 Hz AC input frequency.

The SG Series delivers 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.

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