SUNON KDE2404PFVX Replacement Fan 24V 1.9W 40x40x10mm MagLev (Siemens Inverter)
Replacement internal cooling fan for Siemens SIMODRIVE and SINAMICS drive systems. Direct equivalent to the OEM SUNON KDE2404PFVX — a 40×40×10mm MagLev bearing axial fan, 24V DC, 1.9W, supplied as a single unit with stripped 2-wire leads ready for terminal or solder connection.
This is the standard internal fan used across a wide range of 24V industrial drives. If the existing fan in your drive is noisy, seized, or has stopped spinning entirely, the drive will overheat and either derate its output or fault out — both of which stop the machine. A working 40mm 24V fan is the difference between a drive that runs a shift and one that doesn't.
Common equipment it is fitted to includes:
- Siemens SINAMICS V20, V60, V90
- Siemens SIMOVERT Masterdrives
- Siemens SIMOREG DC masters
- Siemens SIMOTION controllers
- Fanuc spindle drives (24V variant)
- Other industrial 24V DC equipment with a 40mm fan slot
Equivalent / cross-reference part numbers: SUNON KDE2404PFVX, KDE2404PFVX.11.MS.A.GN, 6SL3040-1LA01-0AA0 (Siemens reference). All the same physical fan.
Specs: 24V DC, 1.9W, 80mA, 8500 RPM, 9.5 CFM, 39 dBA, Vapo (MagLev) bearing, auto-restart, plastic frame, 40×40×10mm, 2-wire lead.
