Catalog Data Sheet

CU Series

The CU joins the Corcom family of Power Entry Modules, filling the need for smaller versions of our switched inlet filters. This series provides power entry for equipment designed for popular 1U (1 3/4”) height telecom equipment racks. The filtered versions provide complete shielding, shrouded quick connect terminals and basic filtering for 1A to 15A applications, in an extremely compact size.

The modular design is available in snap-in and flanged mounting options. Filtered versions are also available in a new rear mount style which provides a flush appearance with enhanced EMI shielding. The unfiltered inlet snap-in versions are available in three different snap-in configurations to fit a wide variety of panel cut-outs, and with optional jumpering from the socket to the switch. The CU Series accepts common EN 60320 power cords for international compatibility. Refer to the C, GG, P and M Series PEMs for applications requiring additional features.

‡ 15A versions tested by Underwriters Laboratories to US and Canadian requirements and are VDE approved at 10A, 250VAC
