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
