UMAC Class D?

I would not expect that it has PFC.
The huge caps on the primary indicate the opposite.
There seem to be two switches on the primary.
I would not expect a flyback there (neither with paralleled switches nor an asymetrical half bridge flyback), it is looking more like a typical half bridge converter. Series resonant or LLC.

The smaller transformer might be a flyback for auxiliary supplies, but that's also making me wonder, because auxiliaries could be derived from the main transformer as well.

Just buy one, examine and tell us 😀

Fact is, I am searching for a full bridge class D assembly to run on 175V, so I came across this part. I have good telecom rectifiers, so no need for built-in PSU.
Background of the story is: I d like to put 4 full-bridges together with my rectifiers in one case of ~4U height for a 4 ch amp (2 x RCF Event 4000 tops and 2 x 18G50 woofers). This would give a nice system for my garden home discotheque. At the moment I am more inclined to buy 4 x UCD 2K, but still thinking..... Does anyone know from where within the EU to get the UCD assemblies at a reasonable price?
 
Looking at the cost of 4 x UCD 2K, it ll maybe significantly cheaper to use 1 x UCD2K for the 2 18" in parallel and 2 x UCD700 half bridges for the Tops....hmm... still plenty enough power and headroom for this system, but less versatility for other systems...
