DC Link Capacitors

Alcon Electronics Pvt Ltd manufactures three types of DC Link Capacitors. The series designated DCL 23, has 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 kHz. The internal design uses segmented film. This ensures controlled "self healing". These capacitors can be used in equipments such as induction heating, resonant power supplies, high ripple current circuits to name only a few. The other series, which are designated DCL 41 and DCL 50, are made with polypropylene metallised film and have a maximum voltage rating of 2400 V DC and 1800 V DC respectively. The DCL 41 series are designed for use in UPS systems, wind and solar inverters, traction and industrial drives and are ideally suited for impulse discharge applications such as magnetising and welding. Alcon started manufacturing aluminium electrolytic capacitors for the Indian entertainment electronics industry in 1977. Over the years the focus has shifted and the company now manufactures a large range of high CV screw terminal type aluminium electrolytic capacitors and a large variety of film capacitors. It now caters to the needs of the power electronics sector which includes not only AC drives, UPS systems and inverters but also high frequency induction heating equipment, windmill inverters, defence equipment and telecom equipment, besides a host of several special purpose industrial electronic equipment like health care, welding and pulse magnetizing to name only a few.
