American Electronic Components, Inc. Hvdc Contactor, Spst-No-Dm, 50A, 900Vdc; Load Current Inductive Durakool DEVR05-5061-S8-1012-R1

The Hvdc Contactor, SPST-NO-DM, 50A, 900VDC, part number 67AC7233, is designed for high voltage direct current applications. It features a single pole, normally open contact arrangement and is capable of handling a maximum switching voltage of 900VDC. The rated load for resistive applications is 50A at 450VDC, with a maximum continuous thermal current of 150A for 30 seconds and 250A for 10 seconds. The contact material is AgSnO,ÇÇ, which is sealed in inert gas to enhance durability. The contact resistance is low, with a maximum of 1mOc at 1A. The device operates within a temperature range of -40 to +85¬8C and has a mechanical life expectancy of 1 million cycles. It also includes features such as magnet arc blowout and a pre-charge relay. The contactor is RoHS compliant and has female M4 power terminals for easy installation. Engineers should consider this product for applications requiring reliable switching in high voltage DC environments, particularly where space and thermal management are critical.
