Chargers for the 82162 thermal printer and the HPIL- rs232c - Opotente - 01-11-2001

Anybody knows the technical characteristics for the chargers of the thermal printer and the HPIL - rs232 interface ? I need to manufacture two but wasn't able to find the specs.

Best regards

Why not just buy some?

Anyway -- They're rated at 8 VAC 7 W, however they also not an output of only 3 W, which is about 375 mA RMS.

They're VERY poor in terms of load regulation, so I'd sugest that the specs are not to be taken too literally.

Unloaded, one I just tested measures 12.5 VAC.

You don't have to use an AC source either...
