CUI Intros New AC-DC Power Supplies
AC-DC power supplies.
Tualatin, OR — CUI Inc. has introduced a new AC-DC power supply family targeting applications that demand 100 percent uptime. Available in 75, 100, and 155W configurations, the PSF series is designed with built-in battery charging and back-up functionality. Under normal operating conditions, the units are able to charge the stand-by battery and also supply direct power to the load. In the event of electrical power (AC) failure, the PSF series automatically switches to DC power from the battery source to ensure continuous operation of the system.

The PSF series accommodates a universal input voltage of 90 to 264VAC and is available in two different output formats. The dual output version provides 13.8 and 27.6V; one output powers the load, while the other output is available to charge the battery. The triple output models include an additional 5V, 3A regulated output. The PSF series comes with built-in protection that adds a great deal of flexibility and decreased complexity for the system designer. Protection includes brownout (due to low AC input voltage), battery low cut-off, and battery polarity by resettable fuse. These features are in addition to overload, output overvoltage, constant current limit, and short circuit protection.

The series is available in form factors that include open frame and enclosed versions, with or without a built-in fan. All models carry UL/cUL and TUV 60950-1 safety certifications for ITE, commercial and industrial equipment.
