Sorensen SG programmable power supplies

The water-cooled (or water-ethylene glycol) Sorensen SG series of programmable power supplies have output voltages of 40 and 60 DC and ratings of 5, 10 or 15 kW (max current of 375 A) outputs in a 3U chassis. Up to five chassis can be paralleled for a maximum power of 75 kW.

The series is designed for fast transient response, low noise and high power density that is enabled by water cooling, allowing supplies to be stacked without any required clearance between units.

Two control versions are available: SGA with basic analog controls and SGI with intelligent control.

The SGI version combines onboard intelligent controls enabling sequencing, constant power mode and save/recall of instrument settings. Looping sequences makes the SGI suitable for repetitive testing. User-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 uses 10-turn potentiometers for setting voltage and current and is suitable for applications requiring simple front panel analog controls or external control. Values are displayed on 3½-digit LED readout.

Both SGA and SGI offer optional LXI Class C ethernet or IEEE-488.2 interface.
