Criteria A Conducted immunity EN-4-6 1Vr.m.s Perf. Criteria A Note: 1. Input source impedance: The power modules will 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 HWB-24S and HWB-48S recommended Nippon Chemi-con KY series, μf/v. The HWB-11S recommended Ruby-con BXF series, 68μF/V. 2. (1)Thermal test condition with vertical direction by natural convection (LFM). (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 P/N: 7G-21A-F, 7G-22A-F, 7G-23A-F, 7G-24A-F. Please refer to heat-sink selection guide. 3. The standard modules meet EN5511, EN5522 Class A or Class B with external components. 4. An external input filter capacitor is required if the module has to meet EN-4-4, EN-4-5. The HWB-24S and HWB-48S recommended 2 pcs of aluminum electrolytic capacitor (Nippon Chemi-con KY series, 2μF/V) to connect in parallel. The HWB-11S recommended 2 pcs of aluminum electrolytic capacitor (Nippon Chemi-con KXJ series, 15μF/V) to connect in parallel. 5. CASE GROUNDING : Connecting four screw bolts to shield plane will help to reduce the EMI. 6. For further information, please contact Polytron Devices.
