Default What kinda current....

I'm going to measure the current of my 40mw green labby in my RGY, it seems to be kinda unstable. What kind of current would you expect, MAX for a 40mw labby to need?

Default Re: What kinda current....

Not as much as 500mA, my 35mW labby thats doing closer to 6-70mW only pulls 422mA at 6V.

Which means I can use a 6V 500mA 3VA lead acid battery charger to power it , right ?

That's a 12V charger. The site mislabeled it.

They do both 12V and 6V

He did say max. Postulating poor crystals, this is entirely in the realm of possibilities.

To charge a 6v battery, one needs more than 6v.

Default Re: What kinda current....

It really depends on the pump diode. At 40mW it could use a 200mW 5.6mm pump or it could use a 500mW 9mm pump, each would draw different currents. If it is a 500mW diode It could be drawing a little under an amp, maybe 700mA~800mA (just a guess)

I know that, but it says the charger outputs 6V
