WIMA has reworked and extended its Snubber Capacitor Ranges. The standard lug versions were submitted to thorough verification and - if necessary - adjusted to the requirements of modern IGBTs. The WIMA Snubber MKP range with double-sided metallization and internal series connection was extended by three additional voltage ranges 850 VDC, 1250 VDC and 2500 VDC. The capacitance range now comprises values from 0.047 F up to 8 F and voltage ranges of 700 VDC up to 3000 VDC. As for the especially pulse resistant WIMA Snubber FKP range numerous values were added and case sizes changed. Moreover, a new 1250 VDC range was added. The range now shows capacitance values of 0.01 F up to 3.3 F and rated voltages of 630 VDC to 4000 VDC. more...

WIMA PowerBlock modules based on double-layer capacitors combine the advantage of convertional capacitors as fast suppliers of electricity and batteries as notable energy reservoirs. PowerBlock modules are used for motor start, in railway technology, in hybrid and heavy transportation, in automated guided vehicules (AGV), in uninterruptible power supplies (UPS) or wind power systems. The use of PowerBlocks as energy storage increases efficiency and life time of the applications, saves weight and cost for maintenance, and is environmentally friendly. more...
