Unitec AC intermediate meterThe Unitec AC intermediate meter is regenerated, but not re-calibrated. So it is not a new device. However, the electricity meter is fully maintained and fully functional. It is intended for internal use only. It is not approved for billing purposes. It is a good instrument to better track the power consumption of individual areas in the household. So you can quickly get to track unrecognised power eaters and save money. Another possible area of application is the measurement of solar systems. So you can get an overview of the energy generated. When the power is supplied, you can calculate in advance how much money you can calculate.

The AC meter is regenerated (not a new device, but completely maintained). 10 stands for the rated current of the device in amps (20) stands for the maximum current absorption capacity of the device in amperes. Own consumption approx. 1. Weight: Design may vary



4121133_1.jpg
Own consumptionThe own consumption of the UNITEC AC intermediate meter is about 1 W. The number sequence 10 (40) A means the following: 10 stands for the rated current of the device in amps (mainly relevant to calibration).

(40) stands for the maximum current absorption capacity of the device in amps (maximum current that the electricity meter can withstand continuously without being damaged).

Certification: CE

    You can't refuse a replacement meter if your meter is unsafe or past it's use by date. If your supplier doesn't have non smart meter, they can install a smart meter without the communications unit, effectively making it dumb. They may be reluctant to do that.

    Quoted from the listing "The AC meter is regenerated (not a new device, but completely maintained). 10 stands for the rated current of the device in amps"

    So its a refurb and not a new device and also limited to 10Amps, basically useless for most things.

    Useful for a grasping landlord that wants to fit to a shower so they can charge tenants extra. I had one that fitted a coin-operated shower when I was a student.

    That went as well as you would expect.

    If this was installed in a cupboard next to an electricity meter. Would the meter reader know the difference? Asking for a friend.

    Are ppl selling these as refurbished after removing and installing a smart meter?
    If ppl have time and need to install this, wont they be better off installing a smart meter instead?
    Besides dont all property have one of these already if not already gone smart meter?
