ML350p Gen8 -> Does it need Pure Sine Wave UPS?

hunter86_bg — Thu, 19 Aug 2021 04:06:53 GMT

Hello All,

Currently I have a task to identify a suitable UPS for a ML350p Gen8, but I don't have access to it right now (iLO will be accessible soon).

Does anyone know if ML350p Gen8 power supplies are "Active PFC" ?

Bsed on the topic that was for ML Gen6, it seems that my PSUs are Active PFC and they require pure sine wave or online UPS.

Here is a comment from that topic: https://community.hpe.com/t5/ProLiant-Servers-ML-DL-SL/ML350-G6-UPS-issues/m-p/4548972/highlight/true#M97670

From practical experience, yes, you need true sine wave.
