RB2011/3011 replacement power supply source?

We are looking to find replacement power supplies for the DC24V 1.2 amp units that come in the box. We have had a few fail and want to keep some on hand.

The model number is FLD301-240120-U for the 2011 I just checked but I am sure they chance. The form factor is perfect for us - so I am looking for exact replacements with the same physical dimensions. I have checked the usual suspects but can’t seem to be able to track these down.

Any ideas?

Thanks

Why you don’t just use some other power supply? Any ~15w will work. Laptop ones are the best, work forever. RB3011 requires only 10W max.

yes, cheap power supply do not acomlish advertised rating, a good measure is to buy it over 200% of required real power
