Question 1

I’m working on a small project where I need to build a dimmer circuit for a 6 V AC lamp. I tried using a DIAC, but its breakover voltage is around 30 V, which is too high for my application. I’m ...

Question 2

I want to design an electrical circuit to regulate power of IR heater. I want to be robust, immune to electrical noise, and ensures long-term stability and reliability under real-world operating ...

Question 3

I am looking for a way to test to see if a phase cut dimmer on a 220V AC circuit is set to over a certain approximate percentage of full power, and use the output of that test to trigger a relay ...

Question 4

Hello Electrical Engineering Experts, I’m working on a project where I plan to connect two Luminus CXM-32-35-80-54-AC00-F2-3 LEDs in parallel using a Mean Well ELG-240-54B driver. From my ...

Question 5

I am new to LED drivers and I am trying to set up 0-10 V dimmers in my house. I bought a few Meanwell ELG 100 24B drivers to control 3 groups of pot lights, but I am struggling to control the ...

Question 6

I want to build a triac based regulator to bring a 220VAC 3kW (measured 3.5kW on 230VAC) water heater down to 1kw, I plan on replacing triac on a fan regulator circuit to a better one but I am ...

Question 7

I'm trying to implement trailing edge dimmer for 220 V/50 Hz < 100 W AC load (LED drivers compatible with trailing edge dimming) and would appreciate review of my circuit - will it work or burst in ...

Question 8

I have a question regarding a light fixture I'm building that also has a motor in it. It has geometric shapes that spin slowly around the light (almost like a mobile) and this is what I'm using the ...

Question 9

I am building the dimmer circuit for the LED array. The circuit is based on P-channel MOSFET. The circuit works but I afraid that the MOSFET can be damaged when the potentiometer R1 is in its lowest ...

Question 10

I'm almost hesitant to ask this question because it just seems like I'm going to get lambasted with the obvious but I truly do not know the answer. This is a two prong (no pun intended) question. If I ...

Question 11

I hope my question is not too basic. I'm confused as to how I am supposed to connect a PWM 24V dimmer with my 24V 5-in-1 dimmable power supply. The 5-in-1 has AC inputs (neutral and load), LED- and ...

Question 12

I have a Paulmann 70975 24V LED touch dimmer that I want to use with 12V LEDs. The input voltage is provided by a MeanWell LPV-60-12 12V 5A power supply. The consumer is a 12V 2835 white LED stripe of ...

Question 13

I am all very new to the electrical stuff and perhaps this is an advanced project but hopefully someone can at least point me in the right direction. I am looking to create a PCB that will allow me to ...

Question 14

I'm currently working on designing an incandescent traffic light system and could use some guidance on extending and optimizing my design. Initially, I've successfully implemented the required ...

Question 15

My question is why is this configuration showing an unstable flickering voltage accross the light bulb? Were incorrect capicitance values used? Observing the oscilloscope, I note that there is some ...
