Electrical measurements @ 20C ambient temperature. All data subject to change without prior notice. NOTES For 230 volt operation, connect primaries in series by connecting pins 5 & 4 together and apply 230 volts across pins 6 & 3. For 115 volt operation, connect primaries in parallel by connecting pins 6 & 4 together and pins 5 & 3 together; apply 115 volts across pins 6 & 5. To parallel the secondaries, connect pins 14 to 12 and 13 to 11; take the output across pins 14 and 13. To place the secondaries in series, connect pins 13 to 12 and take the output across pins 14 and 11. Minimum order quantity is 500 pieces per part number. For less than 500 pieces, please contact our distributor Digi-Key Corporation at 800-344-4539 or order on line at www.digikey.com. 22 AMVECO Magnetics, Inc. * 10401 Westoffice Dr. * Houston, TX 77042 * (800) 527-7042 * (713) 977-2500 * Fax: (713) 977-5031 * Email: sales@amveco.com * www.amveco.com
