I found it easier to prise the unit apart from the bottom. At that price, I was curious, how does someone manufacture and sell for some sort of profit a device satasheet can measure up to W of power.

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 front female contacts. Datashest appears that the circuit is using an X2 type capacitor — used to filter out differential mode noise and is connected between active and neutral.

For the low price, how is the current measured. Reviewing the datasheetthe device is a dedicated chip for performing voltage, current and energy consumption calculations.

But, I am aware there are some requirements relating to the types of capacitors that are used. Sorry, your blog cannot share posts by email. Email required Address never made public.

Anyway, a dagasheet shunt is used for the low cost current measurement and a custom IC handles all the power measurement calculations.

This device would be interfacing to the CS via the serial interface. A flat blade screwdriver is useful for prising the case apart. Check out this linkit has some good overview information regarding mains rated caps. Is there some sort of custom IC performing the energy measurement?

Current measurement is performed using a resistive shunt. You are commenting using your WordPress.

Immediately, a resistive shunt used to measure datasheey can be seen on the bottom right of the datasheet PCB. Post was not sent – check your email addresses! Also, is there any scope to hack the device, similar to the Tweet-a-Watt? The two heavy gauge wires are the active connection.

This would be used for the auto-boot function described in the CS datasheet and it would contain calibration and configuration settings.

Or a resistive shunt which would be much cheaper? Once the case is apart, the internals are quite compact. Share your thoughts Cancel reply Enter your comment here
