Criteria A Note: 1. Input source impedance: The power modules wi!! operate as specifications without external components, assuming that the source voltage has a very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the power module. Since real-world voltage source has finite impedance, performance can be improved by adding external filter capacitor. The HWB15-24SXX and HWB15-48SXX recommended Nippon Chemi-con KY series, 1~F/1V. The HWB15-11SXX recommended Ruby-con BXF series, 68~F/2V. 2. (1) Multiple HWB15 series module can be synchronized together simply by connecting the module SYNC pins together. Care should be taken to ensure the ground potential differences between modules are minimized. (2) ln this configuration all of the modules will be synchronized to the highest frequency module. (3) Up to three modules can be synchronized using this technique. (4) More relevant information in datasheet. 3. (1) Thermal test condition with vertical direction by natural convection (2LFM). (2) The iron base-plate dimension is 19 X 3.5 X.63 (The height is EIA standard 2U). (3) The heat-sink is optional and PIN: 7G-21A-F, 7G-22A-F, 7G-23A-F, 7G-24A-F. Please refer to heat-sink selection guide. 4. The HWB15 series standard module meets EN5511, EN5522 Class A and Class B.with external components. 5. An external input filter capacitor is required if the module has to meet EN61-4-4, EN The HWB15-24SXX and HWB15-48SXX recommended 2 pes of aluminum electrolytic capacitor (Nippon Chemi-con KY series, 22~F/1V) to connect in parallel. The HWB15-11SXX recommended 3 pcs of aluminum electrolytic capacitor (Ruby-con BXF series, 1~F/25V) to connect in parallel. 6. CASE GROUNDING: Connecting four screw bolts to shield plane will help to reduce the EMI. 7. For further information, please contact Polytron Devices.
