36V to 12V Dc Converter standby power usage?

[Spacey]

I have a nice little commuter set up with a 36v 12Ah battery pack that is permanently connected to the little 7Amp 250W controller, the controller is turned on by a low power switch connected to a dedicated 'power on' lead on the controller.

This works great and uses next no power on standby, could leave the bike like this for weeks and probably only lose 0.5ah which is fine as it is used/charged every day and the battery will be disconnected from the controller should it be stored for longer than a week.

The problem or worry I have is about the 36V to 12VDC converter which I use to power 2 x 10W halogen lights from the main battery pack. If the lights are turned off would the DC converter use any power on standby?

Yes, it will use power on standby.

Dunno about your dc-dc converter, but i did a test of the lyen dc-dc converter here:

The controller standby power is no worry as it is so small, I'm hoping that as the lights are not on the DC converter will not draw any power by itself, looking at your 0.0025 standby amps usage I think it will be fine left connected.

Cheers for the link.

NP.

I find the controller standby power to be higher than the DC-DC converter actually.. that's on a 14 amp and 30 amp infineon.. both using 0-4 watts to just sit there and twiddle their thumbs.
