PSA150U adapter provides robust construction, increased reliability and longer lifetime

Phihong’s PSA150U Adapter Offers External Power Supply for 100W+ Applications 

Fremont, CA (May 27, 2003) — Giving designers of OEM electronic equipment a robust adapter for applications requiring more than 100W of power, Phihong announces the immediate availability of its PSA150U power adapter. The PSA150U provides an external power supply option for applications that have traditionally required an internal solution. The external alternative increases system space, decreases EMI and reduces heat, thereby increasing safety.

The PSA150U delivers up to 130W of power with 85% efficiency, the highest on the market. Along with increased reliability, stability and overall lifetime of the power supply, the PSA150U adapter's universal AC input range eliminates the need for a voltage switch.

The PSA150U power adapter features a high power density at 130W output, and carries worldwide EMC compliance. It is designed for use in industrial controls, imaging machines, gaming machines, networking systems, portable electronic and telecommunication equipment that require zero down time.

"The PSA150U adapters deliver higher efficiency with excellent thermal characteristics," said Keith Hopwood, vice president of marketing for Phihong USA.  "This 130W adapter, designed and built to our stringent engineering and quality standards, has active protection to prevent damage to product or user loads under short circuit, overload and over voltage conditions without damage."

The PSA150U power supply's high efficiency allows it to minimize heat dissipation, resulting in an adapter that is small and reliable. "Without this high efficiency, the resulting internal temperature rise would be potentially hazardous and a major reliability limiter," Hopwood continued. " In many applications, the adapter may be placed in a confined space, or it may be buried under a pile of cable, so minimizing heat is essential."

The PSA150U adapter is CE compliant, thus reducing system approval cost while meeting conducted and radiated EMI standards. The adapter's robust construction readily survives dips and browns-outs, surges, spikes and lightning strikes.

The unit meets FCC Class B and EN55022 Class B conducted noise limits. Safety approvals pending at this time include UL 60950 3rd edition. Like virtually all Phihong adapters, the PSA150U is approved for UL, cUL and TUV. The product mates with any IEC C13 line cord.

The PSA150U adapter is equipped with an on/off switch and measures 82.34 cubic inches. Pricing is $65.60 each per 100 units, available from stock.

Phihong is the leading adapter brand in the world for the OEM, networking, personal electronic and office automation markets. With global sales for 2002 exceeding $250 million, Phihong has engineering and manufacturing facilities in North and South America, Taiwan and Mainland China.  For information in the U.S., contact Ka Yue Kwok, Phihong, 47800 Fremont Blvd., Fremont CA , 94538, call (510) 445-0100, fax (510) 445-1678, or email, or visit
