The 6AG1961-3BA01-7AA0: SIPLUS PS modular buffer module, conformal coated variant of the 6EP1961-3BA01, rated 40 A continuous, holds output at Vin – approx. 1 V for backup times from 100 ms to 10 s depending on load current. Designed for extended environment use: ambient temperature –25 to +70 °C with natural convection, chemical resistance to cooling lubricants and oil droplets, and derating above 2000 m altitude. Input voltage range 24...28.8 V DC; output voltage tracks input minus approx. 1 V. Galvanic isolation between input and output. MTBF at 40 °C: 2 538 071 h.
Housing snaps onto DIN rail EN 60715 35×7.5/15. Screw terminals at input and output accept 0.5…10 mm² solid or stranded. Enclosure 70 mm wide, 125 mm high, 121 mm deep; IP20. Clearance top 50 mm, bottom 50 mm, sides 0 mm — aligns with standard SIPLUS PS mounting rules.
