B&K Precision Corp. has announced its Model VSP12010 High Power Switching DC Power Supply that is compatible with most computers via a standard RS-232 serial port. The unit uses modern switch mode technology to produce a high power, low noise switching supply. The unit offers 1.2 kW in a 19? rack-mounted chassis that measures 1U in height. The unit, with an output of 0 to 120V DC, 0 to 10A, and it suitable for applications ranging from automatic test equipment to R&D labs to telecommunications. A soft switching technique is said to reduce switching noise, ensuring that the switching action will occur when the voltage across the switching device is at a minimum. A built-in RFI filter further reduces conducted power line noise emissions as well as susceptibility, allowing the supplies to meet EN55022 Class A standards.
