SMX1500RM2UC fan

[lunadesign_apc]

Is it true the fan on the newer SMX1500RM2UC units is always on?

If true, how noisy is it?

Thanks!

@lunadesign_apc,

The SMX models use a variable speed fan and the speed is determined by multiple factors such as operating temperature, mode of operation, and load. This operation may vary depending on the model and firmware revision of the UPS.

We do not have the date for the fan noise but the acoustic level of this unit is 40 dBA.
