Lighting Transformers 230V/240V

I need to replace a lighting transformer in my home, which has, for some reason, given up. It a 240V - 12V transformer, but all I can find in shops is 230V to 11.6V. Obviously the ratios match, but I'm concerned that it'll get too hot if I take it out of its intended operating range. Everything I've seen so far has much larger Tc and Ta numbers that what I have currently. However, there much be an available replacement!

I currently have a DET-65 Dimmable 240V, 50Hz - > 12V eff, Tc = 55, Ta = 40. Does anyone know if a similarly power rated 230V transfomer will do the job, or recommend a suitable replacement?

Regards, Phil

Tc is case temperature and Ta is ambiant temperature (maximums ).

You've got a 65 watt dimmable electronic transformer I'd replace it with one that matches that description.

any modern product marked 230v will run fine on our 240v, which is now officially described as 230v, despite being 240.

Well put!

It was a bit more than 240V the last time I measured it in my house, though still within the acceptable deviation from 230V at the time. It is just a matter of definition.

BTW, I also have some electrical equipment marked as being for 220V, which runs happily on the same supply.

Are short term jumps to 259.5V suffiennt to get th DNO to fix them?

Thanks for the reply, that's exactly what I needed to know.

Check the contract, which usually specifies a voltage range. If it is outwith that range ask your supplier what they are going to do about it. How accurate is your voltmeter and how did you calibrate it?

According to my plug in power meter my supply is presently 217 volts, I've been wondering why the lights look dim lately.
