From November 2018 KVK produces its 800-1 without a transformer. The reason is that the old transformer was intervening with the electricity supply for the LED lights and the computer screen. This could cause black outs, which should not happen. Because the European standard in farms already for many years is the 380V 16A plug with 5 pins in it, KVK decided to take the transformer off. 
We at CowCare have decided to put a new transformer in the pricelist as an extra option, for those clients which have clients that don’t have the 5 pins system but an older electricity system. With the older 4 pins system the 220V will not work on the crush. 
Now all clients can decide themselves if they need the transformer or not.
