New 60W and 25W AC-DC Power Supplies Safely Handle Temporary Overloads at up to Twice Nominal Power

CUI supplies AC-DC power modules which give design engineers the flexibility to specify the supply to suit the system’s nominal power, while supporting temporary operation at twice the rated power for intervals of up to 10s.

Products which support this valuable Power Boost feature include the VOF-S60B series, a family of open frame AC-DC power supplies housed in a board-mount package measuring 50.8mm x 50.8mm x 34.2mm. Offering isolation of 3kV AC and no-load power consumption of less than 150mW, these 60W modules are ideal for space-constrained, low-power computing, industrial and consumer electronics applications.

The Power Boost feature of the VOF-S60B series is also found in another 60W power supply, the 60W PSK-S60B, an encapsulated version of the VOF-S60B units. It is also offered in the 25W-rated PSK-S25B and VOF-S25B. Power Boost provides double the rated output power provided to the load for a maximum of 10s and a repeated duty cycle of 10%.

Doubling the rated current means that these AC-DC products can support large transient loads. The Power Boost feature is ideal for motors and pumps, since these applications need a large power boost to turn on before the power settles at a steady, lower level.
