From 5~100% load, nominal input, 20 MHz bandwidth oscilloscope, with 10 F tantalum and 1 F ceramic capacitors on the output. From 0~5% load, ripple and noise is <5% Vo. 2. 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.comAdditional Resources: Product Page 3D Model CUI Inc SERIES: PYBE20 DESCRIPTION: DC-DC CONVERTER date 08/23/2021 page 2 of 9 PART NUMBER KEY PYBE20 - QXX - X XX - X Mounting Style: Base Number Output Voltage blank = board mount Input Voltage Output: T = chassis mount S = single DIN = DIN-rail mount D = dual INPUT parameter conditions/description min typ max units 24 Vdc input models 9 24 36 Vdc operating input voltage 48 Vdc input models 18 48 75 Vdc 24 Vdc input models 9 Vdc start-up voltage 48 Vdc input models 18 Vdc for maximum of 1 second surge voltage 24 Vdc input models -0.7 50 Vdc 48 Vdc input models -0.7 100 Vdc 24 Vdc input models 5.5 6.5 Vdc under voltage shutdown 48 Vdc input models 12 15.5 Vdc 3.3 Vdc output models 818 mA 24 Vdc input models 5 Vdc output models 993 mA all other models 969 MA current 3.3 Vdc output models 409 mA 48 Vdc input models 5 Vdc output models 497 mA all other models 485 mA turn on (3.5~12 Vdc or open circuit) 4 remote on/off (CTRL) turn off (<1.2 Vdc) input current when switched off 4 7 mA filter Pi filter input reverse polarity protection only present on chassis mount and DIN-rail mount models no load power consumption 0.15 W Notes: 4.
