Test/develop EV/HEV and PV applications with 500-V DC PSU

June 21, 2013 // By Paul Buckley
AMETEK Programmable Power has added to the company’s Sorensen SG Series high-power DC power supply line with the introduction of the new Sorensen SG 500V.

The power supply is able to supply up to 500 V DC for applications such as driving amplifiers, and testing inverters, batteries and power steering pumps used in electric vehicle/hybrid electric vehicles (EV/HEV).  

The Sorensen SG Series claims to be one of the industry’s most widely used DC power supplies in its class with more than 20,000 units in the field.  The quality of power supplied by the Sorensen SG Series makes it well suited for a broad range of applications. 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 500 V DC model of the SG Series 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, exceptional load transient response, and low RMS ripple and noise. Combinations of these chassis can then be easily 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 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-capable unit ideal 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.
