Emergency power engineering, 75KVA powerbloc, ups
This unit is an AC Motor-Generator set that is used to provide power to the load during prime power failure. This unit will run the load for 90 seconds after prime power
failure, in that time a back-up generator (not included) must pick up the load. This is accomplished by an inertia flywheel attached to the same axis as the motor and generator.
A “By-Pass Switch for maintenance†is included to put the load directly to the Prime input 480V through a transformer to provide the 120/208V to distribution.
Input is 480 V, 3 phase 3 wire + gnd.
405A with load on by-pass and Motor/Generator start-up
Output is 120/208V, 3 phase, 4 wires + gnd. 75 KVA, 0.8 pf.
Output is available on 2ea. 42 pole distribution panel boards 120/208V
Some documentation available, 1 line drawings of the control circuits and the units power circuits.
This item is very heavy, ~ 4000lbs.
