Page 3: Applications
Applications KATKA 80ST 690 series of thyristor switching modules have been designed especially for switching power factor correction capacitors in rapid reactive power compensation (up to 20 control interventions in one second) in conjunction with fast power factor controllers of the NOVAR series. They can, of course, be also used in other applications where contact-less load switching is required. -

Page 5: Installation Of Katka Into Cabinet
Installation of KATKA into cabinet During normal operation, modules produce great amount of heat. Therefore it’s necessary to provide sufficient air flow in the cabinet (holes in bottom and top of the cabinet) and sometimes also use of active cooling (use of fan) might be necessary. -

Page 11: Maintenance, Service, Warranty
Maintenance, Service, Warranty Maintenance: the KATKA 80ST 690 modules does not require any special maintenance during its operation but following should be respected. For reliable operation heat sink should be cleaned regularly from any debris and dust as cooling performance can be reduced otherwise. Also regular inspection of fan operation (when equipped) should be performed.
