Mona asked Can solid state relays vary output voltage or are do they just supply a set voltage that is turned on or off?
By that I was wondering if it would be possible to use a microcontroller to vary the voltage that a SSR supplied to its output connection (say, to vary the voltage supplied to a heating element). If not, what might be a better option to vary the voltage via microcontroller?
And got the following answer:
You already have a good answer on SSRs generally. But you aren't clear. Are you ACTUALLY trying to control a heating element? Or is this just a general example, but not your real application? If it isn't what you are trying to do, what exactly ARE you trying to do? What is the voltage range you want to control and what is the current compliances required? How much precision over the range is required? You also don't say if this is a DC application or AC. SSRs can be designed for either, but they are different things. Finally, if it is a heating element and you are dealing with AC, it's mass and slow behavior will integrate (sum) fast pulses of energy, so you can use an SSR for that, using (half-)cycle skipping or else using phase-angle control to adjust the net power applied. But inductance or capacitance in the load may affect the choices you make here. SSRs do NOT increase voltages or decrease them. They switch them (apply them) ON or OFF, with a small loss being incurred inside. Given that you suggest a heating element and because such elements can be on the order of 1000 watts or more, you may also need to deal with dissipation issues in the SSR itself. So be aware of that issue, too. A google search turned up a couple of link you may look at. The 2nd one, on page 2, shows a synopsis of methods to look over.
The small solid state relay work very well with distinctive applications which can be certain to energy distribution and protection. The relays include wide adjustment ranges using a scale which is easy to study either in 3 or four digits in line with the model. These small solid state relay help in escalating the flexibility in the applications, lessen the all round energy and maintenance charges. There are actually relays which are utilized for basic purposes which are available in dependable styles with rapid replacement alternatives. And you can find models which are employed for industrial applications and heavier duty applications that operate on substantial loads. These items are made to meet the lifetime industrial manage requires of the applications.
