I just wanted to spare the ~1 month wait until a new bed arrives, I could not find any round 24V heated beds in my country.
My initial tought process was the following:
From the viewpoint of the bed:
It has a large thermal mass, so if I send pwm with high enough freauency (probably anything above 5hz would suffice) then it should not have a problem with it.
From the viewpoint of the PSU:
It was not rated anywhere close to this power, so I should use small impulses to steal small amounts of energy from the output capacitors, so it would represent a tolerable load, however if I use frequencues too high I might start some rezonance effect somewhere.
From the viewpoint of the panel:
The switching element generates most heat during switching on or off, because that is the point where both current and voltage are present, so I should use a relatively low the pwm freq, which is high enough to not fluctuate the switching element temperature.
It does not metter now, I threw the idea away because of the previous advices, so I'll just have to wait.
