CUI’s expanded portfolio of AC/DC power supplies offers an optional power boost function that delivers twice the rated power for up to 10 seconds.

CUI’s expanded AC/DC supply portfolio offers an optional power boost feature that delivers twice the rated power for up to 10 seconds for systems that employ motors or pumps. Doubling the rated current means these AC/DC power supplies can handle large transient loads, allowing engineers to design for nominal rather than peak power.

Nine new series—the PSK-S12B, PSK-S25B, PSK-S60B, VOF-S12B, VOF-S25B, VOF-S60B, VOF-S12C, VOF-S25C, and VOF-S60C—furnish 12 W, 25 W, and 60 W of continuous power in both chassis-mount and board-mount packages. PSK board-mount units are encapsulated, while VOF board-mount supplies come in open frames. Both the PSK and VOF board-mount lines have an input voltage range of 90 VAC to 264 VAC and 3-kVAC isolation. Chassis-mount units available in the VOF series also accommodate an input voltage range of 90 VAC to 264 VAC.

All of the AC/DC power supplies provide single outputs ranging from 5 VDC to 48 VDC and comply with UL/EN/IEC 62368-1. The PSK-S12B/S25B, VOF-S12B/S25B, and VOF-S12C/S25C are additionally designed to meet the UL/EN/IEC 60335-1 household standard.
