Digital Wattmeter With Voltage And Current Display

Usb output i can be utilized for device charging and data transfer.

Digital wattmeter with voltage and current display.

Simultaneous display of voltage and current voltage measurement range dc 0 100v current measurement range 0 10a power measurement range 0 1000w specifications. Operation of the wattmeter is controlled by two pushbuttons left and right from the display. 0 10a power measurement r. In this project potential transformer is used to step down ac voltage from 220v ac to 15v ac.

The apparatus voltage and current inputs are insulated between each other. The dual monitor has an easy to read display making it incredibly easy to control the charge going into your appliance. In the default operation mode left button toggles measurement ranges 0 9 and auto ranging a while right button rotates through the list of measured quantities true and apparent power power factor voltage and current maximum voltage and current consumed energy anharmonicity impedance and equivalent serial inductance capacitance etc in menu mode which is selected by pressing left button.

Wattelec measures the trms effective values of the u i w measurements possibly with direct component superimposed. The output of the line voltage transducer is connected to the ade7751 at voltage channel v2.

The wide bandwidth of the apparatus allows measurements to be made from dc to 70khz or on chopped signals frequency converters industrial choppers rectified supplies etc. Us 22 02 us 24 24 9 off 5pcs xl4015 5a high power 75w dc dc adjustable step down module led. There are two usb outputs available used simultaneously. Ic ade7751 receives two analog inputs load current and voltage at its two channels v1a and v1b as current channel and v2n and v2p as voltage channel in the form of a differential voltage input using current and voltage transducers.

This paper presents a design to produce a microcontroller based digital wattmeter that measures the magnitude of power consumption of various loads electronic devices connected through it. Wattelec is a digital multimeter with floating inputs simultaneously displaying the 3 electric values. Whether you want to charge mobile devices or you want to move data between the mobile device and pc just plug a device in output i. It counts the numbers of impulses and hence the duration and display the value of voltage on led or lcd display after calibrating it.

Now we are in situation to understand the working of a digital voltmeter as follows. Ac voltage measurement using pic microcontroller and potential transformer.
