The VW3AE1401 is an additional 24 V DC power supply delivering a nominal 1.6 A, designed as a control accessory for Altivar floor-standing enclosures with separate air flows or the compact version of Altivar 61 Plus and Altivar 71 Plus drives. It runs on a 230 V AC supply. This is the auxiliary supply that powers the drive's control logic and I/O independently from the main DC bus — useful when you need the control section alive while the power stage is off, or when the main DC bus can't supply the full 1.6 A the control chain draws.
This supply is destined for the Altivar floor-standing enclosure with separate air flows or the compact version — meaning it mounts inside the drive cabinet, not on a separate DIN rail. It feeds the 24 V DC control bus for the drive's logic, I/O, and any option cards. The 1.6 A rating covers the typical control draw of a single Altivar 61 Plus or 71 Plus with a modest I/O complement; if you're loading it with multiple option modules or fieldbus cards, verify the total 24 V DC draw stays under 1.6 A.
