Hi all,
I'm a graduate student currently working on the neurobiology of addiction and pain, with an interest in the design of a novel thermal gradient ring that can be controlled between -5 degrees C and 60 degrees C (see the first attachment). Unfortunately, I'm definitely a novice when it...
My goal is to rewire a Peltier AC unit by removing the on-board PSU and Analog temperature controller.
I would like to convert the AC unit to Cool and Heat by reversing the Peltier modules polarity.
Then control both heating and cooling functions with a PID. Then running it all with an external...
Hello experts,
I've been trying to build a small home automation project using ESP32, PubSub client and an MQTT broker on Android. Rest all is fine, but I was trying NOT to use a relay for controlling the appliances. While considering Solid State Relays, I came across ACST1635 from ST...
What are the potential risks in using a solid state relay for a load between 10-20A? I've found HP rated SSR's with a surge current graph that I believes fits the characteristic of the inrush current of an AC or DC motor, but I also read that the peak current of the motor must be half the...
Can a 4-20 mA (constant VDC) analog output on an industrial controller be used as an input on a solid state relay? I wasn’t sure how a device behaving as a variable current source might interact with a load such as the LED in an solid state relay that varies in its current draw. For example...
I am using a couple pumps that are manufactured to be run from a standard wall outlet. I've learned that upon starting, both AC and DC motors can have inrush currents of several times the rated current, but I'm unsure how to determine if these pumps have any internal limiter on inrush current...
