(1) multiple DCHB200 series modules can be synch ronized together simply by connecting the module sy nc pins together. care should be taken to ensure the ground potential differences between t he 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 n otes. 3. maximum output deviation is +10% inclusive of re mote sense and trim. if remote sense is not being u sed the +sense should be connected to its corresponding +output and likewise the sense shou ld be connected to its corresponding Coutput. 4. (1) thermal test conditions for vertical direct ion are by natural convection (20lfm). (2) the iron baseplate dimensions are 19 x 3.5 x 0.063 (the height is eia standard 2u). (3) heat sink is optional. see the model number s etup table on page 7 for suffix options. 5. the DCHB200 standard models (without assembly op tions) can only meet en55022 class a or class b wit h external components added. 6. an external input filter capacitor is required i f the module has to meet en6100044, en6100045. we recommend connecting two aluminum electrolytic capacitors (nippon chemicon ky series, 220f/100v ) in parallel. 7. output voltage is adjustable for 10% trim up or 20% trim down of nominal output voltage by connec ting a single resistor between trim and +sense pins for trim up or between trim and sense pins for tr im down. to calculate the value of the resistor r u and r d for a particular output voltage see page 7. 8. case grounding: emi can be reduced when you conn ect the four screw bolts to the shield plane. 9. this series comes with several different options : negative remote on/off control, heatsinks, case p in, sync pin, pin length, terminal block, and thru hole inserts. see the model number setup table on pag e 7 for more ordering information. caution: this power converter is not internally fused. an i nput line fuse must always be used.
