VOF-S25B Power Supplies w/ Power Boost Option

CUI Inc VOF-S25B Power Supplies with Power Boost Option feature an open-frame design in a compact, board-mount package that measures 50.80mm x 27.94mm x 24.90mm. These 20W/25W power supplies provide 3kV_AC isolation, a 5V_DC to 48V_DC voltage configuration range, and <150mW no-load power consumption. The VOF-S25B series offers an optional power boost that doubles the rated current to support large transient loads, allowing users to design for nominal power rather than peak. This boost can double the rated output power provided to the load for a maximum of 10s and a repeated duty cycle of 10%. CUI Inc VOF-S25B power supplies are designed for space-constrained, low-power information technology equipment (ITE), consumer electronics, and industrial applications.
