Milpitas, Calif., Sept. 17, 2020 – Digital Power Corporation (“DPC”), a wholly owned subsidiary of Coolisys Technologies Corp. (“Coolisys”) is introducing its new industry leading High Density (“HD”) AC/DC power supply/switcher product line targeting the medical, industrial and telecom sectors. This new product series is designed for very high operating efficiency and power density with universal input and built-in active power factor correction (“PFC”).

The new HD Series is a power switcher product line that can produce a single output of 12VDC, 24VDC, or 48VDC and offers high power in high-density packaging even under natural convection cooling conditions. The new product line features a compact, low profile footprint, and best-in-class performance, optimized for broad industrial, telecommunication and medical applications. Additionally, the ability to operate within a wide temperature range make this new HD Series ideal for commercial off-the-shelf (“COTS”) implementations for the defense industry.
