PQA50-D Series, Ultra-Compact 50 W DC/DC Converter

CUI's PQA50-D is one of the industry's smallest 50 W DC/DC converters. The series feature set makes it ideally suited for IT equipment, telecom and industrial systems. The DC/DC converter series is a low-cost, high-performance family with a 2 x 1 inch (50.8 mm x 25.4 mm) footprint, an industry standard size for less-powerful devices. It incorporates six-sided metal shielding for improved EMC performance and efficiency up to 93%. The converters maintain high-efficiency figures across the entire input voltage range, including under light loads, making the PQA50-D series ideal for designs where minimizing power consumption at various operating conditions is a priority. The single-output isolated DC/DC converter modules feature a 2:1 input range, and are available with an 18 VDC to 36 VDC or 36 VDC to 75 VDC input voltage range and 3.3 VDC, 5 VDC, 12 VDC, 15 VDC, or 24 VDC output voltages. The series has 1500 VDC input-to-output isolation and protections for output over-voltage, short-circuit, over-load, and input under-voltage. The series offers precise voltage regulation, featuring load regulation of ±1% max. from 10% to 100% load-and-line regulation of ±0.5% max. Additional features of the PQA50-D series include an operating temperature range of -40°C to +85°C, remote on/off control, and voltage adjustability of ±10%.
