The E48SB product family features an input voltage of 38V to 55V, and provides up to 240W (9.6V and above) of power in an industry standard eighth brick footprint. Typical efficiency of 9.6V module is 96.5%. With optimized component placement, creative design topology, and numerous patented technologies, the E48SB bus converters deliver outstanding electrical and thermal performance. An optional heatsink is available for harsh thermal requirements. Positive On/Off logic Short pin lengths Heatsink available for extended operation OTP and OCP mode (Auto re-restart or latch) APPLICATIONS Datacom / Netowrking Wireless Networks Optical Network Equipment Server and Data Storage Industrial/Testing Equipment DATASHEET DS_E48SB9R625_01232007 TECHNICAL SPECIFICATIONS (TA=25°C, airflow rate=300 LFM, Vin=48Vdc, nominal Vout unless otherwise noted.)
