Press Release Summary:
Suited for 1U-height, single-output applications, PAS250 uses passive PFC technology and meets all Class A PFC requirements. In operation, unit provides universal 115/230 Vac input selection and single 250 W continuous power output. User can select one of several factory-set output voltages, including 12, 24, and 48 V. Measuring 7.0 x 4.0 x 1.5 in., unit is protected against overload, overvoltage, reverse voltage, and thermal conditions.
Original Press Release:
New 250W Switcher's Passive Power Factor Correction for Class A Equipment Offers Lower Cost Per Watt Than Active PFC Supplies
Universal-input/single-output PAS250 offers 1U form factor, higher reliability than other PFC technologies
SAN MARCOS, CA-June 15, 2004-TAIYO YUDEN (U.S.A.), Inc. introduces the PAS250, the second model in its new PAS Series of affordable, passive PFC-based, switch-mode power supplies for 1U-height single-output applications. Like its 150W companion model (PAS150), the PAS250 provides tremendous economic benefits to OEMs through use of passive versus active PFC technology. Not only is active PFC more complex and less reliable than passive, active also provides unnecessary functionality at higher cost, the result of the recent de-classification of many Class D end devices to less stringent Class A harmonic distortion standards per EN61000-3-2. The PAS250 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 PAS250 is significantly less than a comparable switch-mode power supply employing active PFC techniques.
In operation, the PAS250 switcher provides a universal 115/230VAC input selection and a single output of 250W continuous power. The user may select one of several factory-set output voltages, including 12V, 24V and 48V. The PAS250 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 ISO9001-certified facilities in North America, the PAS250 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 PAS250 switcher physically measures just 7.0" (L) x 4.0" (W) x 1.5" (H) and comes with a two-year warranty.
Now in its 54th year, Tokyo-based TAIYO YUDEN CO., LTD. is a worldwide manufacturer of surface-mount and leaded passive components, Bluetooth modules, power electronics modules, power supplies, and recordable digital media. With approximately 50% of the worldwide market in high-frequency multilayer chip inductors used in cellular phone applications, the company reports annual sales of nearly US$1.4B. Worldwide, TAIYO YUDEN employs more than fifteen thousand people, and the company's North American affiliate, TAIYO YUDEN (U.S.A.), INC., operates sales and engineering offices in: Chicago, IL; Raleigh, NC; Irving, TX; San Jose, CA; and San Diego County.
