Topic: Ua5 How long will my battery last??

[hoobash]

I have run my ua5 that much and dont know the run times. The ua-5 is 450ah. I have a 9.6v 3000mah and 1600mah so this the correct math??

3000/450=6.6 hours
1600/450=3.5 hours

I know they wont run for the full amount of time. I am not using phantom power

[caymanreview]

usually take the capacity/ draw *.8

The deneke ps-2 phantom box pulls 280, so just to be safe say the ua-5 w/o phantom on is only pulling 250, with .8 (can't drain 100%) factored in. that gives you 5 hours on a 1600mha

I've never run longer than 4.5 without switching, but it's a safe bet.

Can any of the electronically inclined tell us how to measure the actual amp draw of the ua-5 w/o phantom on?

place a multimeter in SERIES in (+) side of the power supply and measure the current (amperes).

for example:

[ battery  ] (+) _________ MULTIMETER ________________ [ua5]
(-)|__________________________________________________|

Ah, thanks.

I'll have to try that on saturday, since I have to go right from work to a show again tonight (bad plus this time)

I'll post results asap

So you get 4.5 hours on 1600ma?? That means I should easly get 8-9 hours on the 3000ma

Just reread some of what ya wrote....not sure I'd assume it's using the same amount as the ps-2......I just seem to remember phantom being used doesn't add much draw as 200+mAh.


I am probably wrong though.

Sorry gang,

My multi-meter is not multi enough. Does not measure amperage.

And I thought I was cool because I had a fancy digital multi-meter.

I measured this a year or so ago.  The 2 numbers were measured from battery and ac sources respectively.  I don't know why they were different but they were.

phantom off   260, 280
phantom on, mics attached   360, 390

add 20mA if driving headphones
