Reply To: ASUS Router UPS … Hi all, As the power frequently goes out during bad weather/wind for a few seconds and coming back on, I’m considering getting a UPS which will power by router and…

So have had feedback from ASUS regarding supported UPS waveforms, ASUS (routers division) have spoken with their various power adapter manufacturers and ….

ASUS has discussed with their power adapter manufacturers and they (adapter manufacturers) claim the adapter should work with all 4 waveforms.

• true sine waveform
• stepped sine waveform
• modified square waveform
• square waveform

However, there are many manufacturers and some of the older products (adaptors),  ASUS cannot guarantee all work with all 4 waveforms types.

There is a single concern regarding “Modified Square Wave”, since there is a period of time with ‘0’ Volts, the adapter works or not is dependent on the specification of the UPS and the amount of time the adapter spends at ‘0’ volts.

However ASUS believe if the time the wave is at ‘0’ volts is only 2-3 msec then there should be no issues.

So does sound like ….

Both true sine waveform and stepped sine waveform is a safe option,  modified square waveform is more interesting.
