Sorensen DC power supplies with outputs to 15 kW can noe be ordered with water cooled option The Sorensen SG Series of programmable DC power supplies with output voltages of 40 volts DC and 60 volts DC can now be ordered with a water cooled option in place of speed controlled fan cooling. Ratings of 5kW, 10kW or 15kW (max current of 375 amps) outputs in a 3U chassis, allowing up to 5 chassis to be paralleled for maximum system power of 75kW.
Paralleled units operate like a single supply. Input voltages of 400 and 480 volts, three-phase. Water cooled DC power supplies are especially suitable for harsh or dusty environments that prevent the use of conventional fan cooling. The SG Series is designed for fast transient response, low noise and high power density which is enabled by water cooling that allow supplies to be stacked without any required clearance between units.
The Sorensen SGA 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 that enable sequencing, constant power mode and save/recall of instrument settings. Looping of sequences makes the SGI suitable for repetitive testing.
Operator friendly features include a clear vacuum fluorescent graphical display in eight languages, context sensitive “soft” keys, front panel keyboard simplified programming and RS-232 interface. The SGA version is suited for applications requiring simple front panel analogue controls or external control and utilises 10-turn potentiometers for setting voltage and current.
Values are displayed on a 3 ½ digit LED readout. Both SGA and SGI DC power supplies offer optional LXI Class C Ethernet or IEEE-488.2 interface.
