The DC Series filters were designed as general-purpose line filters for DC applications. They are available with or without circuit breakers for extra protection and with feed-through capacitors for added performance (contact your local Allied sales representative for more information). This series was developed in response to the increasing demand for DC filtering in the telecom-datacom market. They can also be used at the primary input of the DC power supply. The DC Series is designed to comply with UL 1283*, CSA 22.2 No.8 and EN60950. The DC Series was developed in response to the increasing demand for DC filtering in the telecom-datacom market. These filters are generally used in central office equipment like switches, routers, and hubs to clean up the 48 VDC power, but are not exclusive to that equipment. They can also be used at the primary input of the DC power supply. The DC Series is available in both a flange mount (DCF) and bulkhead mount (DCB) configuration
