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.
