an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC), shown in the figure 1. In the post, I will focus on current sensing stage that needs to be low-drift and low-noise. To read more, refer to the technical articleHow to desi...
Insert your wireless router’s AC adapter to the DC-IN port and plug it to a power outlet. After connecting to the power supply, remember to press the Power button to turn on the router. Make sure the power LED indicator on the front of the router is on. The WiFi 2.4G/5G LED indi...
Filter:After rectifying, a filter is used to smooth out and minimize the pulsating DC voltage. Typically, due to their ability to store energy, capacitors are used in this kind of filter circuit. Regulator:To have a stable DC voltage value output, avoltage regulatoris needed. It ensures a ...
This paper is meant to be a comprehensive how to guide to help measure voltage, measure current, and measure power with computer based instrumentation.
If the DC power cable of the 3G router has a standard USB connector with the maximum operating current of less than 1 A, it can be directly connected to the USB port on the SmartLogger.Connect the USB connector of the DC power cable for the 3G router to the USB port on the ...

This process is repeated as long as the load current is below the power-save current threshold. The ADP2138 is a compact 800-mA, 3-MHz, step-down dc-to-dc converter. Figure 4 shows a typical applications circuit. Figure 5 shows the improvement in efficiency between forced PWM and ...
Current is equal to voltage divided by resistance (commonly written as I = v / r). This makes intuitive sense: If you increase the pressure working on the electric charge or decrease the resistance, more charge will flow. If you decrease pressure or increase resistance, less charge will ...
Twist together the free lead from the 1-kiloohm resistor with one end of the second wire. Connect the loose end of this wire to the negative terminal on the power supply. Turn the power supply on Turn on the voltmeter and set the scale to measure "Volts DC." Place the black voltmeter...
Facility managersand property owners know that appliances that emit more heat are something that you should avoid. That’s because they increase cooling costs and pose a hazard to employees. While it is unavoidable to use such equipment in particular situations like factory settings, it is always...
