CUI’s line of 2:1 and 4:1 input DC-DC converters ranging from 10 W to 50 W are housed in a slim, compact chassis-mount package. The PYB10-T, PYB15-T, PYB20-T, and PQA50-T are ideal for battery-driven applications, including transportation equipment, mobile equipment, and telecom base stations, where charging and discharging conditions require an ultra-wide input range. All units come standard with an operating temperature range of -40°C to +85°C, providing a rugged solution for use in harsh environments. The PYB-T series, available in 3.3 VDC, 5 VDC, 12 VDC, 15 VDC and 24 VDC single output models and ±5 VDC, ±12 VDC, and ±15 VDC dual output models, carries a 4:1 input with voltages of 9 VDC to 36 VDC or 18 VDC to 75 VDC. The PQA50-T, on the other hand, carries a 2:1 input range with voltages of 18 VDC to 36 VDC or 36 VDC to 75 VDC while offering single regulated outputs of 3.3 VDC, 5 VDC, 12 VDC, 15 VDC, and 24 VDC.
