Switch-Mode Power Supply offers 1U form factor.

Press Release Summary:




Model PAS150 delivers passive power factor correction for Class A equipment. It offers 115/230 Vac input selection and single output of 150 W continuous. User may select one of several factory-set output voltages, including 3.3, 5, 12, 24, and 48 V. Switcher features DC OK, AC power fail, and protection against overload, overvoltage, reverse voltage, and thermal conditions. Current sharing for 1+1 redundancy with no special interconnection is optional.

Taiyo Yuden's New 150W Switcher Provides Passive Power Factor Correction for Class A Equipment-at Lower Cost Per Watt than Active PFC Supplies



Universal-input/single-output PAS150 offers 1U form factor, higher reliability than other PFC technologies

SAN MARCOS, CA-August 15, 2003- TAIYO YUDEN (U.S.A.), Inc. introduces the PAS150, the first model in its new PAS
Series of affordable, passive PFC-based, switch-mode power supplies for 1U-height single-output applications. The PAS150 provides tremendous economic benefits to OEMs by employing passive PFC technology-versus the more complex, less reliable, active PFC technology that now provides unnecessary functionality at higher cost, thanks to the recent de-classification of many Class D end devices to less stringent Class A standards per EN61000-3-2 harmonic distortion standards. The PAS150 switcher not only meets all Class A PFC requirements, but also provides greater reliability and higher MTBF (mean time between failure) through use of fewer components. Also, the relative cost per Watt of a passive PFC switcher like the PAS150 is significantly less than a comparable switch-mode power supply employing active PFC techniques.

In operation, the PAS150 switcher provides a universal 115/230VAC input selection and a single output of 150W continuous power. The user may select one of several factory-set output voltages, including 3.3, 5, 12, 24 and 48V. The PAS150 switcher features optional current-sharing capability for 1+1 redundancy with no special interconnection requirement. Other options include remote on/off, and droop or single-wire current sharing with OR-ing diodes. The standard unit provides superb heat dissipation, but is also available with an optional fan with its own 12VDC supply. Other standard features include: DC "OK," AC power fail, and protection against overload, overvoltage, reverse voltage and thermal conditions.

Manufactured in the company's IS09001-certified facilities in North America, the PAS150 is ideal for the full spectrum of low power OEM supply needs, featuring quick prototype delivery and Highly Accelerated Life Testing (H.A.L.T.) to verify design parameters and ensure 100% out-of-the-box operation. The PAS150 switcher physically measures just 6.0" (L) x 4.0" (W) x 1.5" (H) and comes with a two-year warranty.
