I took your advice after trying to manually control my element with the potentiometer a bit more. The results were worse than I had remembered. I changed my code. I now have great control over my element controlling with the pot. I made a 10 step program where step one turns the SSR on for...

Sorry, I suppose I should've been more clear as well. My pump is 24VDC and is controlled by a DC SSR (which is indeed a MOSFET) with DC input (PWM also). So no problems here, it works beautifuly. My element is 220VAC 5500W and is drvien by a 50A AC SCR with DC input (PWM in this case). The...

The AC SSRs (at least the Crydoms I'm using) are rated at max turn on time of 1/2 cycle, and a max turn off time as 1/2 cycle as well. I would think that for one on/off cycle at 60Hz we would need a max PWM frequency of 60Hz. If you notice the first variable in the code, I've provided a...

I use an Adafruit PRO Trinket for the PWM controller with a 10 turn potentiometer connected to 5v,Gnd, and Analog In "1" (A1). The output PWM pin then just goes to an SSR-->pump. I also use this little chip to operate the element in manual mode. I can expand this to operate as many as 6 PWM...

The seller has edited their ad, and it now has waaay less info on this pump. I was able to pull up the original ad for the pump from my order history--> 100% Brand New Dimensions: Approx 9cm x 5cm x 7cm (L x W x H,3.51x 1.95x 2.73inch ) Color: Black Rated voltage: 24V DC. Rated current: 1050mA...

Hi guys, first post! After lurking and reading through this entire thread a couple weeks ago (yes, the whole thing), I decided try a couple cheap chinese pumps. I just received 2 of these 24VDC pumps from eBay (one is just a spare): Eo56 pump also at AliExpress: Eo56 (TK1226) pump They claim to...
