Product Information

Additional two resistors R8 and R9 are used to sense the supply voltage of the power supply that will be stressed by this dummy load. As per the voltage divider rule, these two resistors support a maximum of 24V. More than 24V will produce a voltage that will be not suitable for the Arduino pins. So be careful not to connect power supply that has more than 24V output voltage. Below are tables with all the options for the unit, along with the error codes I’ve been able to decipher from the Chinese info available in various places online. (If anyone knows better, do let me know!). Option No circuit exists that will allow you to use a 10W capacity heatsink in a 500W electronic load. If you need to get rid of, say, 500W, you will need heatsinks/fan combinations that can get rid 500W without getting too hot. If the heatsink is too hot to touch, it is probably not suitable and you will need a much better one. I have already discussed a simple and effective electronic load controller circuit in one of my previous posts, the present idea is inspired from it and is quite similar to that design.

The rotary encoder is used to select the option. Function 2 is battery capacity test mode. Beeper Mode Meng-Yueh Chang; Jiann-Yow Lin; Shih-Liang Jung; Ying-Yu Tzou (1997-06-27).

S2CID 111355663. A reasonably calculateddummy load is attached in series with the ELC, and P1 is adjusted such that the dummy load slightly illuminates and adjusts the generator speed and frequency to the correct level as per the required specs. A dimmer switch is a mains operated electronic device which can be used for controlling an attached load such as lights and fans simply by varying an associated variable resistance called a pot.

In Electronics All-in-One For Dummies, you'll find a plethora of helpful information, from tinkering with basic electronic components to more advanced subjects like working with digital electronics and Arduino microprocessors.

Electronic circuits may contain resistors or capacitors in series, parallel, or a combination. You can determine the equivalent value of resistance or capacitance using the following formulas: How to work with alternating current, direct current, analog, digital, and car electronics, as well as Raspberry Pi technologies In the above condition it assures that at 220V while all the domestic loads are in use, 9 additional dummy loads also illuminate, and compensate to produce the required [email protected] dummy load ordinarily should be a pure resistance; the amount of resistance should be the same as the impedance of the antenna or transmission line that is used with the transmitter (usually 50 Ω or 75 Ω). [2] Versatile chips— find out how to use analog and digital integrated circuits to build complex projects with just a few parts So far we learned an effective electronic load controller circuit using a sequential multiple dummy load switcher concept, here we discuss a much simpler design of the same using a triac dimmer concept and with a single load. What's a Dimmer Switch Conversely if the pot resistance is reduced, the triac is restricted to conduct proportionately for a much smaller section of the phase cycle, making the load weaker with its activation.
