Measured at nominal input voltage, full load. The typical efficiencies for the chassis mount and DIN-rail mount versions are ~2% less than the board mount versions due to the input reverse polarity protection. 3. All specifications are measured at Ta=25C, humidity < 75%, nominal input voltage, and rated output load unless otherwise specified. cui.com Additional Resources: Product Page | 3D Model | PCB Footprint CUI Inc SERIES: PYBE20 DESCRIPTION: DC-DC CONVERTER date 01/24/2019 page 2 of 11 PART NUMBER KEY PYBE20 - QXX - X XX - X Base Number Input Voltage Output: S = single D = dual Output Voltage Mounting Style: "blank" = board mount T = chassis mount DIN = DIN-rail mount INPUT parameter conditions/description min typ max units operating input voltage 24 Vdc input models 48 Vdc input models 9 18 24 48 36 75 Vdc Vdc start-up voltage 24 Vdc input models 48 Vdc input models 9 18 Vdc Vdc surge voltage for maximum of 1 second 24 Vdc input models 48 Vdc input models -0.7 -0.7 50 100 Vdc Vdc under voltage shutdown 24 Vdc input models 48 Vdc input models 5.5 12 6.5 15.5 Vdc Vdc 24 Vdc input models 3.3 Vdc output models 5 Vdc output models all other models 818 993 969 mA mA MA 48 Vdc input models 3.3 Vdc output models 5 Vdc output models all other models 409 497 485 mA mA mA 7 mA current remote on/off (CTRL)4 turn on (3.5~12 Vdc or open circuit) turn off (<1.2 Vdc) input current when switched off filter Pi filter 4 input reverse polarity protection only present on chassis mount and DIN-rail mount models no load power consumption Notes: 0.15 W 4.
