500-V Power Supply Fills Out Programmable DC Line

June 21, 2013. AMETEK Programmable Power has added to its Sorensen SG Series high-power DC power supply line with the introduction of the new Sorensen SG 500V, which can supply up to 500 VDC for such applications as driving amplifiers and testing inverters, batteries, and power steering pumps used in electric vehicle/hybrid electric vehicles (EV/HEV).

The Sorensen SG Series has 20,000 units in the field. Along with the testing of EV/HEV components, applications include the driving of amplifiers used in airport and medical MRI/CT scanners, magnet drivers for particle accelerators used at National Laboratories and medical proton treatment systems, and drivers for laser diodes for cutting and etching tools.

The new 500-VDC model of SG Series power supplies can provide up to 15 kW in a 3U package and 30 kW in a 6U package. Users also can select from 5-kW, 10-kW, 20-kW, 25-kW, and 30-kW models. The Sorensen SG Series also offers fast voltage and current slew rates, fast load transient response, and low RMS ripple and noise.

The complete SG Series includes a 3U and 6U package configuration with a variety of output and power configurations. Combinations of these chassis can then be paralleled to achieve power levels up to 150 kW.

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 on-board intelligent controls with the 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-capable unit suitable for repetitive testing using complex or compliance waveforms. The unit features an eight-language, vacuum-fluorescent graphical display, context sensitive soft keys, and simplified front-panel keyboard programming. Units with SGI control come with a standard RS-232C port. GPIB/IEEE 488.2 and LXI Ethernet ports are optional features.

Units with SGA control are designed for users who require simple front panel analog controls or external control. They have the same high- performance power electronics as the SGI and provide essential features such as 10-turn potentiometers for setting voltage and current and 3½ digit LED readout with front-panel over-voltage protection (OVP) preview/adjustment and reset. Units with SGA control come standard with remote analog control. They can be fitted with an RS-232C port, a GPIB/IEEE 488.2 port, and an LXI Ethernet port as optional features.

An SG Series option is a factory-installed dust filter. Other options include a low-cost ANSI/NCSL Z540-1 Certificate of Calibration (CoC).

In addition to Sorensen, AMETEK Programmable Power brands include AMREL, California Instruments, Elgar, and EM Test.
