Criteria A Conducted Immunity EN61000-4-6 10 Vrms Perf. Criteria A NOTES 1. Input Source Impedance: These converters will operate under all listed specifications without external components assuming that the source voltage has very low impedance and reasonable input voltage regulation. Highly inductive source impedances can affect the stability of the converter. Since real world voltage sources have finite impedance, performance can be improved by adding an external filter capacitor. We recommend Nippon chemi-con KY series, 100 μF/100V. 2. (1) Multiple DCHB200 series modules can be synchronized together simply by connecting the module SYNC pins together. Care should be taken to ensure the ground potential differences between the modules are minimized. (2) In 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 the application notes. 3. Maximum output deviation is +10% inclusive of remote sense and trim. If remote sense is not being used the +SENSE should be connected to its corresponding +OUTPUT and likewise the -SENSE should be connected to its corresponding –OUTPUT. 4. (1) Thermal test conditions for vertical direction are by natural convection (20LFM). (2) The iron base-plate dimensions are 19” x 3.5” x 0.063” (the height is EIA standard 2U). (3) Heat sink is optional. See the “Model Number Setup” table on page 7 for suffix options. 5. The DCHB200 standard models (without assembly options) can only meet EN55022 Class A or Class B with external components added. 6. An external input filter capacitor is required if the module has to meet EN61000-4-4, EN61000-4-5. We recommend connecting two aluminum electrolytic capacitors (Nippon chemi-con KY seri es, 220μF/100V) in parallel. 7. Output voltage is adjustable for 10% trim up or -20% trim down of nominal output voltage by connecting a single resistor between TRIM and +SENSE pins for trim up or between TRIM and -SENSE pins for trim down. To calculate the value of the resistor RU and RD for a particular output voltage see page 7. 8. CASE GROUNDING: EMI can be reduced when you connect the four screw bolts to the shield plane. 9. This series comes with several different options: negative remote on/off control, heatsinks, case pin, sync pin, pin length, terminal block, and thru-hole inserts. See the “Model Number Setup” table on page 7 for more ordering information. CAUTION: This power converter is not internally fused. An input line fuse must always be used. |
