Most of our hydraulic controllers have R&R RB2 units, theyre 500 watts.
We also have a few with the Dynavect LR750, which is 750-watt and a newer and fancier design.
Both of them work good and we haven’t had any issues.
Some companies use commercial computer UPS, but we prefer not to use them as they are not designed for elevators and sometimes fail operating heavy doors.
