Hi,

Happy new year to everybody.

As I understand, the WS-12-250-DC switch has 250 W maximum power and 9 to 60 V input voltage range.
Can we have 250 W maximum power even with low voltage power source like 9 Volts ?
If yes, I am a bit surprised because this would make around 28 A input current.
If not, what would be the maximum input current on the WS-12-250-DC ?

I need to know this to figure out the maximum power I can get in practice with my quite low voltage power supply.

Thanks a lot for your kind help and support.

Again, best wishes for this new year.

Best regards.

No, at 9V the POE budget is 100 to 150 watts

Hi,

Thank you very much for your reply.

The information you provide looks clear and detailled. Thanks a lot.

I would also have another question.
In 4 pairs mode, pinout is pins 1,2,4,5(+) 3,6,7,8(-).
One of the microwave radios we plan to use has pinout 1,2,7,8(+) 3,6,4,5(-).
Can we setup 1,2,7,8(+) 3,6,4,5(-) on the WS-12-250-DC ?
If yes, this is great.
If not, do you think I can power my 1,2,7,8(+) 3,6,4,5(-) radio with the WS-12-250-DC ?
In other words, considering your experience, do you think most good quality microwave radios has 2 rectifier bridges on their PoE input ?
Of course, I do not ask you to guarantee anything, I just ask you about your feeling and your experience.

Thanks a lot for your kind support.

Best regards.

Most radios do not have the ability to deal with polarity pin out change, have bridge rectifier circuit.

I would not try it unless you first ask the manufacturer of the radio and explain the pin out the switch provides polarity on.

Hi,

Thank you very much for your reply.

We will contact the radio manufacturer and ask them.

Thank you for your kind support and advice.

Best regards.
