MKP 300-207 SPECIAL POWER CAPACITORS
MKP 300-207 SPECIAL POWER CAPACITORS
FOR HIGH PULSE LOADING AND HIGH FREQUENCY INDUCTION HEATING
Construction:
Special winding units soldered on metal plates, whichensure good cooling of the capacitors. The winding unithave non-inductive, self-healing construction,
Applications:
The capacitors are designed for use in high power andhigh pulse loading and in high frequency resonantcircuits of induction heating devices.
The construction of contact-plates are adaptable inaccordance to customer requirements.
Technical data:
Rated voltage UR: 1500DC up to +70°Crecommended working voltage 1200 ÷ 1500VDC,depend on the cooling-condition and workingfrequency. Rated voltage is the max. DC or peakvoltage, for which the capacitor is designed.
If the capacitor works with the DC and alsosuper-imposed AC voltage UAC, the sum of DCand the amplitude of AC must not exceed the UR
Max permissible AC voltage: 700 VRMS/50Hzby good cooling. If the working frequency is higher,the permissible AC voltage must be decreased,not to exceed the max. loss power of the capacitor.
PL =Uef2x 2πf x CR x tgD
The max. loss power must to be lower thanmax. power dissipated by the capacitor under thecooling-condition. The power, which the capacitor canradiate
PR = S x ∆ T x K
