Energy Meter Teardown
Sorry, your blog xs5460 share posts by email. I found it easier to prise the unit apart from the bottom. Reviewing the datasheetthe device is a dedicated chip for performing voltage, current and energy consumption calculations.
This would be used for the auto-boot function described in the CS datasheet and it would contain calibration and configuration settings.
Immediately, a resistive shunt used to measure current can be seen on the bottom right of the green PCB. Current measurement is performed using a resistive shunt.
It appears that the circuit is using an X2 type capacitor — used to filter out differential mode noise and is connected between active and neutral. Email required Address never made public. When in service, current from the rear male prong connects to the obscured red wire, passes through the resistive shunt and then through the other red wire to the adtasheet female contacts.

Learn how your comment data is processed. Or a resistive shunt which would be much cheaper? There is some scope for customisation here. At that price, I was curious, how does someone manufacture and sell for some sort datashet profit a device that can measure up to W of power.
You are commenting using your Facebook account. Anyway, a resistive shunt is used for the low cost current measurement and a custom IC handles all the power measurement calculations.
Does the device use a current transformer CT? Once the case is apart, the internals are quite compact.

The two heavy gauge wires are the active connection. A flat blade screwdriver is useful for prising the case apart. Fill in your details below or click an icon to log in: Is there some sort of custom IC performing the energy measurement? A bonus is that the serial interface pins are clearly labelled on the PCB adjacent to the ribbon cable on the top right.
This device would be interfacing to the CS via the serial interface. Share your thoughts Cancel reply Enter your comment here Notify me of new comments via email.
