For more information, please visit the product page. CUI Inc │ SERIES: NQB-N │ DESCRIPTION: FULLY REGULATED ADVANCED BUS CONVERTERS The input voltage range 40 to 60 Vdc meets the requirements for normal input voltage range in -48 V systems, -40.5 to -57.0 V. At input voltages exceeding 60 V, the power loss will be higher than at normal input voltage and TP1 must be limited to absolute max +125°C. The absolute maximum continuous input voltage is 65 Vdc.
