COSEL Expands Microprocessor Controlled Power Supplies
Cosel presents 3000W AC/DC enclosed power supply for industrial and demanding semiconductors applications with FETA3000BA an advanced built-in COSEL’s digital microprocessor technology.
Cosel Co, Ltd announced the addition of a 3000W AC/DC enclosed power supply for industrial and demanding semiconductors applications. Designed with advanced built-in COSEL’s digital microprocessor technology, the FETA3000BA includes active current sharing, making it simple to parallel up to 10 units for extra power or redundancy. For high efficiency, the FETA3000BA includes an active filter and uses a phase-shift, full-bridge topology offering an efficiency level of up to 93%. Addressing industrial applications and semiconductors equipment, the FETA3000BA complies with the SEMI F47 standard.

With an input voltage range of 170 to 264VAC, the FETA3000BA-48 delivers an output voltage of 48VDC, adjustable from 38.40 to 52.80VDC using the built-in potentiometer, or 15.00 to 52.80VDC when using the trimming function available at the rear connector. The nominal output current is 62A and efficiency is up to 93% at 230VAC input.
Operated utilizing COSEL’s digital microprocessor technology, the FETA3000BA series integrates a very sophisticated voltage and current balance control. This simplifies system integrators’ task when connecting units in parallel or series. This technology makes it possible to connect up to 10 units in parallel, without adding any other external components. The advanced digital control also controls switching parameters to optimize efficiency, thus reducing energy consumption.
"Power supplies, which used to be a mass of analog technologies, have been going through major changes since the turn of the century. Once controlled by switching devices ON and OFF in an analog circuit based on output voltage monitoring, they are now controlled digitally by microprocessors and software," said Mr. Todo,
