Wattson Solar Monitor

Really need a favour!

My power supply broke and got put to one side... ie lost!

Could someone check their power supply and tell me how many amps?

I believe it's 9v DC but don't know the amperage. Please help!

It's either a new PSU or buying the smappee device!

There should be two power supplies : one for the Wattson unit itself, another for the wireless sender unit. I can't actually find my Wattson unit at the moment but have found the sender unit.

I vaguely remember that both PSUs were the same. The one I have found is rated at 9V (because the sender unit input socket is labelled 9V) but has no data plate on it. It can't be that critical because the sender unit will also work if 4 x AA batteries are used (i.e. only 6V). Also, if batteries will do the current needed must be a few milliamps at most so any PSU you can find (providing polarity correct) that supplies at least 6V and preferably not more than 9V will do the job. Even if such a PSU is capable of supplying several amps, the Wattson will only draw what it requires.
