Thanks a lot!

Solenoid project is actually running on a 12V power supply plugged to an ac wall outlet. The next and final step is to provide the whole gig with battery power to render it entirely...

Thanks engr3000 for your suggestion. Much appreciated. Early last week I ordered the TC1427 gate driver along with recommended caps. The project now works perfectly. The response time of the solenoid...

Thanks Pete. Probably dumb question but can I put two 10K resistors in parallel to sum-up 20K between gate and source? I don't have 20K resistors.

Update on the project

My solenoid project is almost completed but I'm struggling with an issue. I hooked up the gate pin of the MOSFET IRL540N to the digital pin 23 of my ESP32 (Wemos D1) but unfortunately the gate is not...

engr3000: oh, ok. That's an interesting point. Since the switching ON of the solenoids needs to be very fast and instantaneous from the mouse click so they are activated in sync with my computer...

engr3000: Thanks for confirming the FET transistor choice. Since the gate is fed with usb's 5v coupled with resistor, I have faith that no spike will ever occur that could ruin that gate. This chip...

I also thought of using a Bluetooth shield onto an Arduino instead of a mouse in order to communicate with a pc and close the 5v loop onto the transistors. This way there's no wired connection...

telecom guy: the 450w number is the max power available on the 12vdc psu. The 2 solenoids will not need that much power. But it is always better to have more power available than not enough. As for...

Hi all,

I performed several tests with my three 400w-motor motion base plugged on a regular 15amp 120v line and so far, no problem. The breaker didn't trip. More over the test were performed on a...

Thanks Lambition and Pilot Dane. I verified my old meter and it won't be of any use since it has a limit of 200mA (0.2 amp) in DC. No option for 15 amp metering in AC. It's a pocket size model that...

Lambition,

Before trying the option of plugging the psu's to 240v I will do a first test on a regular 120v ac outlet to see if the circuit can take the load. I will start with 3 motors. The total...

I will have to abandon the idea of using a 240v line to feed the power supplies since I've just realized that these units use a L - N - FG (Live, Neutral, Ground) input. A 240v line in North America...

True, good catch Ray. I was using the old "110v" expression but I meant 120v ;-)
