Eltek Flatpack S 48V 150A 2U DC Power System (CTOS0502)

Product Introduction

The CTOS0502 Compact HE Flatpack S 2U DC Power System is a highly integrated rack-mounted power solution launched by Eltek. Equipped with classic Flatpack S 48/1800HE high-efficiency rectifier and Smartpack S intelligent controller, this all-in-one unit integrates power conversion, distribution and monitoring functions. It adopts a 2U low-profile design with a shallow depth of only 270mm, which is compatible with most standard cabinets and serves as an ideal replacement for old power equipment. The system supports 85~305V AC and 85~250V DC dual wide input, with a rated output of -48V DC, maximum current up to 150A and total output power reaching 9kW. All rectifier modules, controllers and circuit breakers support hot plugging, enabling maintenance without power cut. Built with diversified power distribution circuits and optional LVBD/LVLD protection functions, it complies with multiple international electrical and EMC standards. This reliable power system is widely deployed in mobile communication base stations, fiber access networks and other telecom scenarios.
