Product Data Sheet 300 WATT AC/DC POWER SUPPLY NX301 DESCRIPTION The NX301 is a compact 300 watt Power Factor Corrected, multiple output power supply. All outputs are fully isolated and regulated. Active current sharing circuitry, together with control functions and alarm options, simplifies N+1 and redundant applications. Fan and disk drive applications are handled by the peak current ratings of the auxiliary outputs. FEATURES � Active Power Factor Correction � Fully Isolated Outputs � Low Profile: 9” x 4.85” x 2.00” � One, Two, Three and Four Output Models � N+1 Current Sharing � FCC/VDE Class B EMI Filter Standard � Optional Fan Mounted On Cover AGENCY APPROVALS 3400 E Britannia Drive � Tucson, Arizona 85706 � Phone: 520.295.4100 � Fax: 520.770.9369 � Internet: http://www.cdpowerelectronics.com NX301 3/98 REV B Page 1 Input Specifications Parameter Conditions Min Typ Max Units Operating Range 47-63 Hz 90 264 VAC Inrush Current Limiting 120VAC, cold start 35 APK 240VAC, cold start 70 APK Efficiency 120V 120V, full load 70 % 240V 240V, full load 75 % Power Factor Correction (PFC) 0.99 Meets IEC 1000-4-7/EN61000-3-2 (formerly IEC 555-2) Remote Sense Power Fail Signal Remote Sense is provided on Output #1 and will Upon AC input voltage removal, the power fail signal drops compensate for 0.7V of line drop. Remote Sense leads to logic zero at least 5msec before loss of DC output. On AC input turn-on, signal remains low until outputs are in are protected against open, short and reversal. regulation.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
