UEI-3.3/18-Q48NR-C电源-板安装的直流转换器规格书PDF中文资料

PRODUCT OVERVIEW

Wide range 4:1 inputs on the 1.50 x 1.90 x 0.38 converter are either 9 to 36 Volts DC (Q12 models) or 18 to 75 Volts DC (Q48 models), ideal for battery-powered and telecom equipment. Fixed output voltages from 3.3 VDC to 15 VDC are regulated to within ±0.05 and may be trimmed within ±10 of nominal output. Applications include small instruments, computer-based systems, data communications equipment, remote sensor systems, vehicle and portable electronics.
