This bipolar power source with zero crossover distortion was developed to control beam positioning magnets in particle accelerators and scientific laser applications.
This power source is a high precision linear amplifier that connects to and turns an ordinary DC unipolar voltage source into a precise bipolar power source with zero crossover distortion. This class AB linear amplifier is rated at 160A @ 25V and contains less than 5mV p-p voltage ripple. Used in conjunction with an “off the shelf” unipolar voltage source, the supply produces a precision bipolar output capable of sourcing +/- 160A with a compliance of +/- 25 volts into a load.
Air cooled and housed in a 3U rack mount enclosure, the APS20 is easily configured for new or existing applications. As with all APS power products, all critical components are monitored and protected against failures due to overvoltage, overcurrent or over temperature. The front panel displays indicate output voltage and current, heatsink temperature, fuse failure and fault status.
