TUALATIN, Ore. — June 17, 2014 — CUI Inc announced the release of a new ac-dc power supply family targeting applications that demand 100% uptime. Available in 75 W, 100 W and 155 W 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 90~264 Vac and is available in two different output formats. The dual output version features 13.8 V and 27.6 V – one output goes towards powering the load, while the other output is available to charge the battery. The triple output models include an additional 5 V, 3A regulated output. The PSF series comes with built-in protections that add a great deal of flexibility and decrease complexity for the system designer. Protections include brownout (due to low AC input voltage), battery low cut-off, and battery polarity by resettable fuse. These features are in addition to over-load, output over-voltage, constant current limit, and short circuit protections.
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.
The PSF series is available through distribution with prices starting at $73.59 per unit at 100 pieces. Please contact CUI for OEM pricing.
