BC-U2 to power F3
 

I am using the above charger to power my F3 via a Vortex Media cable. However, the camera presents with a low voltage warning? Any ideas?

There's probably something wrong with your BC-U2. I use the same configuration and don't get any low-voltage warnings. Can you test the output voltage?

I use the same and it works perfect

Good to hear that it should work ... guess I'll drag out the old multimeter.

I checked the voltage output from my BC-U2 and it reads a steady 12.2 volts. My connection to the F3 was via a 4 pin XLR adapter cable, and I wonder if the problem could lie there within. I have no way of testing the cable and have just sent off an email to the supplier to see what they have to say.

isn't there something in the menu where you can set your power warning, just change the voltage to a lower voltage.

If it's even possible—haven't come across that menu option—and if the camera's warning is accurate, changing the voltage will only serve to squelch the warning. I suspect that the camera's reading is accurate because it went to battery power while I was updating to firmware Ver 1.4, and I can confirm this by the drop in battery charge after the process was complete.

On a cheap analog voltmeter mine looks like it registers around 12.6 V or so.

Your really pushing the limits of the BC-U2 if you have the A/B SDI outputs on. The F3 draws 2 amps when everything is on, while the BC-U2 is rated at 2 amps, running power supplies flat out like that is never good long term. I use a 3 amp supply with my F3.

Hi Alister,

Yes, I agree. I found that the camera read the BC-U2's output as 11.9 volts at rest—no camera activity. And I assume that it called for more amps than the unit could supply during the firmware update. I just ordered an IDX power supply—4.4 Amp, 13.5 volts, 60 Watt— that will hopefully do the job.
