Yes during startup, but under normal running condition.
What to expect from a ABB during start up? I know there is many ways to set up the ABB for starting up the motor, but the time is not an issue, an example could be 15 sec. But can I expect 2 x kVA during start up? I know the UPS needs to...
Okay I follow you jraef, especially about the soft starter.
Worst case could be kVA equal kW if we are looking at the UPS. We have a lot of equipment connected to this UPS (cameras, computers, IFF, radio, radar etc.). Which typically uses a controlled and know amount of power. But for the...
Sorry guys,
It is 6 poles and 930 rpm - so I guess the effency is "low" due to a slow engine.
We am trying to size a UPS towards worst case - and even though full load is the best efficiency it will be still be "worst case" right?
Meaning: 400 x 6 x 1.73 = 4.15kVA.
4.15k x 0.83 = 3.44 kW...
Hi there,
I have tried to figure this one out buy searching, but without any results.
My case: On the nameplate for my motor it says:
Star: 3x400V / 2.2kW / 6.0A
Delta: 3x230V / 2.2kW / 10.4A
I am not sure about the efficiency but why is the motor power 2.2kW?!?
400 x 6 x 1.73 = 4.15kVA
230...
