Each Alpha power supply is built custom to meet customer requirements. We try to limit ourselves to units above 5 kilowatts. Our proprietary control circuits can regulate to better than 0.001% (10ppm). We have several standard power supply topologies available. The one we use will depend on the specific requirements of a particular unit. Because the units are “built-to-order” we have ability to customize such things as cabinet size, color, terminal locations, etc. A full complement of options are available, including:
• remote interfaces
• specialized controllers
• multi-channel output units
• polarity reverse switches
Each unit is thoroughly tested into an appropriate load. (In the cases of very powerful units, final site testing may be required). Strip charts are produced showing current stability for various disturbances (line changes, load changes, etc).
