product brief 2011 power capacitors mkk-dc / mkk-dci (-h) / mkk-dc-r characteristics and properties high performance gas-impreg- nated capacitors offered for applications with medium volt- age from 1500 to 3000 v dc and medium currents, with clear advantages in terms of lightness and reduced cost. oil-impregnated capacitors are alternatives when applications demand high operating temp- erature and currents, resulting in critical heating that is more effectively evacuated by oil. this technology in oil is also more suitable for applications with high nominal voltages of >1800 v dc and/or high ripple voltages above 400 v rms. polyurethane resin-filled capa- citors are offered in low voltage applications with high currents due to their more simple con- struction with less compo- nents. the resin acts as insula- tor and heat conductor. in those cases where due to constraints in the application, the design of choice as ex- plained above is not advisable or appropriate, a special custom-made design with another technology is possible. applications ? dc-voltage applications for dc link ? resonant filtering ? frequency converters housing ? rectangular non-magnetic stainless steel case ? ferric steel, aluminum www.epcos.com

power capacitors ? epcos ag 2011 mkk-dc/mkk-dci/mkk-dci-h: mechanical considerations and construction general description the mkk-dc/mkk-dci/mkk- dci-h capacitors are designed in rectangular ca ses made of austenitic stainless steel. the cases are hermetically welded and the surface is not pain ted. fixing brackets and bolts are mounted to fix the capacitor. bolts are used also for the ground connection. different types of terminals are available for the terminal connections. the capacitors should be exclusively handled by the fixing brackets. in no case the terminals should be used to lift the capacitor. capacitors will usually be mounted upright (terminals on top), but can be mounte d in any position keeping a distance of 25 mm minimum between large facets, to allow for thermal expansion and effective cooling. standard design dimensions the following table shows the available standard dimensions. deviations from these dimensions are available upon request. tolerances are indicated in the drawings as well as the maximum thermal expansions during normal operation conditions. the label is located centered to the length and 50 mm from the top of the case. labeling: manufacturer (company logo), ordering code, connection diagram, version, rated capacitance, tolerance, weight, insulating voltage, iec standard, country of origin, month/year of manufacturing. h1 mm h2 mm h3 mm mkk-dc 340 605 805 mkk-dci 340 605 mkk-dci-h 340 605 terminals and connections standard terminals are available as shown below. brass bolts, tinned, with di fferent metrics in male and possibility of female connection, are available upon request. insulation material of the terminal is epoxy according to cti 600. the following table shows the maximum continuous currents acceptable (for a temperature increase in the terminals of +15 c), th e maximum torque and the contact surface of standard terminals. other specific options ar e available upon request. please contact our local sales office . terminal m16 max. current 265 a max. torque 25 nm contact surface 505 mm 2
