Programmable power supplies provide 1700 watts in 1U height

Ametek Programmable Power has introduced a higher power version of their high density 1U rack height programmable power supply. The Sorensen XG1700 is available in 12 different models with maximum output voltages up to 600 volts and currents up to 220 amps.

The new Sorensen XG1700 series offers the highest power level currently available in a 1U full rack casing. Front ventilation ensures that units can be stacked at full density without the need for ventilation spaces above or below.

High frequency, soft switching technology is used to provide low output noise coupled with high power efficiency. The technology also minimises the stress on the switching devices thus providing high higher mean time between failure (MTBF).

The 1700 watts of output power can be provided in both constant voltage and constant current modes, and special fold-back modes can be selected if required. Bus controlled auxiliary output voltages are available for switching connection relays or for other switching requirements.

The Sorensen XG series comes as standard with USB 2.0, RS-232, RS-485 and non-isolated analogue interfaces to provide a comprehensive set of options to connect to a PC or other network device. Isolated analogue, LXI compliant Ethernet and GPIB interfaces are available as options

The Sorensen XG series is exclusively available in Great Britain from TTid.

Expanded range of programmable DC power supplies includes 800 V model

TTi Distribution are now distributing the Sorensen SG Series of programmable power supplies expanded to include a 0-800 V DC offering. This expanded voltage range makes the unit ideally suited to use in applications such as test systems for hybrid vehicles and power inverters.

The SG Series is available with 5 kW, 10 kW or 15 kW power ratings in a 3U chassis, allowing up to five units to be paralleled for a maximum system power of 75 kW. Paralleled units operate like a single supply.

The SG Series is designed for exceptional load transient response and low noise, and provides the highest power density in the industry. This power density is complemented by a stylish front air intake that allows supplies to be stacked without any minimum clearance between units.

The Sorensen SG Series is available in two control versions: SGA with basic analogue controls and SGI with intelligent control features. The SGI version combines onboard intelligent controls with high-performance power electronics that enable sophisticated sequencing, constant power mode and save/recall of instrument settings. Looping of sequences can also be implemented, making the SGI ideal for repetitive testing.

The SG Series features a high-quality vacuum fluorescent graphical display in eight languages, context-sensitive 'soft' keys, a front-panel keyboard, simplified programming, and an RS-232 interface.

The SGA version is suited for those customers requiring simple front-panel analogue controls or external control. It has the same high-performance power electronics as the SGI, and includes features such as 10-turn potentiometers for setting voltage and current and a 3½-digit LED readout.

Both the SGA and SGI offer optional LXI Class C Ethernet or IEEE-488.2 interfaces.
