as above, has been asked to quote and install a UPS device for a security shutter at my local doctors surgery. Problem they have is they are looked out if theres a power cut as there is no manual crank.
I have had this and installed a computer backup unit which is rated for the load
most shutters are worm drives so low current
it wont run the system continuesly but not realy needed open in the morning shut at night
