Which transformer to use with VMB3PS?


I am sure that my question will be stupid… :? :oops:

I thought first that the VMB3PS was a transformer.
But I read that it needs an additional power supply… so, what is the exact job of the VMB3PS ?

How to choose a transformer for tha VMB3PS ?
Where can I find a DIN-Rail one ? (Belgium)



The VMB3PS contains rectifier, smoothing caps and protection so it transforms the AC from you transformer to a smooth DC voltage plus it features short-circuit protection. The transformer can be bought from any store which supplies your electrical material. Make sure to calculate the required transformer rating. For a single power supply unit, a 40VA transformer is OK (see manual).
