DC power supply suits hybrid vehicle test systems
Thurlby Thandar Instruments
Sorensen SG programmable power supplies
The Sorensen SG Series of programmable power supplies has been expanded to include a 0-800V DC offering that is suited for applications such as test systems for hybrid vehicles and power inverters.
The SG Series is available with 5, 10 or 15 kW power ratings in a 3U chassis, allowing up to five units to be paralleled for a maximum system power of 75kW.
Paralleled units operate like a single supply.
The SG Series is designed for exceptional load transient response and low noise, and is claimed to provide the highest power density in the industry.
This power density is complemented by a 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 31/2-digit LED readout.
Both the SGA and SGI offer optional LXI Class C Ethernet or IEEE-488.2 interfaces.
