Hi,
Of course the voltage is 10V and 23V, I was just going from memory as the Transformer I was looking has a 30V tap too.
I managed to find a Transformer on Aliexpress that has 30V 0.3A, 24V 0.55A and 10V 0.3A.
https://www.aliexpress.com/item/32933762833.html?spm=a2g0s.9042311.0.0.34964c4dZ4Y9L4I assumed 1V difference wouldn't do any harm and should be within tolerance.
The triac model in mine is an ST BTA41600B rated VDRM/VRRM 600/800V and the Capacitor is rated 275VAC.
I am not sure if there is anything else I have missed, what do you think?
EDIT: I Forgot to add that my unit also has the ON MOC3041 which on the data sheet does state its for 115VAC Applications.
I assume this makes it much more tricky to convert and is not just swapping out that Optocoupler
I took the PCB out and it appears to be the following components:
C9: 275V WMEC MPX 0.1K
R4: 001 Resistor
R2: 331 Resistor
U1: ON MOC3041
R9: 331 Resistor
Q1: ST BTA41600B
If I could get a board scan or someone to show those parts from a 230V Version, then I should be able to replace them no problem.
Thanks for your help,
Kind Regards
Jamie
