DC-Link Capacitors

Alcon manufactures three types of DC Link capacitors:


The series designated DCL 23, have a very low equivalent series inductance (ESL). The coaxial construction can give an ESL as low as 11 nH. These features make them suitable for use at high resonant frequency 61 to 460 K Hz. The internal design uses segmented film. This ensures controlled "self healing". These capacitors can be used in induction heating equipment, resonant power supplies, high ripple current circuits to name only a few.


The DCL 41 and DCL 50 series are made with metallised polypropylene film and have a maximum voltage rating of 2400 VDC and 1800 VDC respectively. The DCL 41 series are designed for use in UPS systems, wind and solar inverters, traction and industrial drives. The DCL-41and DCL -50 series are ideally suited for impulse discharge applications such as magnetising and welding.
