Refer to Ill. 1. GENERAL CHARACTER AND USE: This product is a switching type power supply incorporating semiconductor components in the primary circuit. It is provided with input and output terminals for connection to the end use equipment. The power supply has been investigated to , Standard for Information Technology Equipment including Electrical Business Equipment CAN/CSA C22.2 No. 60950-00, UL60950, CAN/CSA C22.2 No. 950-95, UL1950 3rd Edition., UL 1012, Standard for Power Supplies, Sixth Edition. The Mega/Master Modules are dc-dc power supplies consisting of 1 to 3 Recognized (QQFU2) Vicor dc-dc converter modules combined together to provide 1 to 3 outputs. A Mega Module provides a single output. A Master Module provides 2 to 3 outputs. Input voltage varies based on dc-dc converters selected and can be between 300 V dc and 12 V dc. Output voltages can be between 95 V dc and 2 V dc. Output powers can be between 100 W and 25 W for each output. NOMENCLATURE BREAKDOWN: Refer to Ill. 1. ELECTRICAL RATINGS: Refer to Ill. 1.

Conditions of Acceptability - When installed in the end-use equipment, the following are among the considerations to be made. 1. These components have been judged on the basis of the required *spacings in the UL 1012, Fifth Edition, and Information Technology Equipment including Electrical Business Equipment, CAN/CSA C22.2 No. 60950-00, UL 60950, CAN/CSA C22.2 No. 950-95, UL 1950 3rd Edition, which covers the end-use product for which the component was designed. 2. The power supply should be installed in compliance with the enclosure, mounting, spacings, temperature, casualty, and segregation requirements of the ultimate application. 3. The Normal Temperature Test should be repeated in the end-product investigation. The baseplate temperature should be measured and should not exceed 100°C. File E135493 Vol. 1 Sec. 6 and Report Page 5 Issued: Revised: 7-13-94 6-23-00 4. Secondary outputs 5 V - 40 V have been investigated for secondary interconnection and are compliant with SELV requirements in the configurations described in this report. Secondary outputs 48 V - 95 V are nonSELV outputs. 5. The input and output terminals are not acceptable for field connections and are only intended for connection to mating connectors of internal wiring inside the end-use machine. The acceptability of these and the mating connectors relative to secureness, insulating materials, and temperature should be considered. 6. The "Gate In" and "Gate Out" terminals are in low voltage primary connected circuits. 7. All testing was conducted using the input fusing specified below. This fusing is not provided as part of the module and must be provided in the end-use.
