I wonder if it is possible to supply an electric motor tubular curtain via UPS (in case of power failure) and whether yes at what price?
acid To know that the engine has a power 230/50 absorbed about 400W.

There he dedicated UPS single-phase motors or a "simple" UPS will do the trick?

I would not want to use a generator: (.

In advance thank you

A simple inverter would be sufficient , however, provide a model of peak power well above the motor starting current of the motor being imposrtant enough

Thanks for responding so quickly.

You think an off-line UPS 800VA will shock the engine start, or I have to take a lot more powerful?

Sorry seek details but the price is important because the cost of the UPS must not exceed that of a replacement engine TBT

The starting current of an electric motor is 4 to 8 times the rated current up to 10 times for non-inverter chillers, A UPS 800 VA should be enough q'il accepts a power surge from 1500 to 2000 VA, there should be tests, if you do you can lend equipment

Mareson, invites you to lend equipment for testing. Be careful though. inverters the most common are those who help the computer. The protections are not calibrated for the operation of a motor. N ' is there not on your curtain, a walkout to open it manually in case of power failure ?

Install a UPS for a curtain is, I think you it's luxury.
How many times there are power outages, and for how long.
The manufacturer curtain has certainly provided a mechanical operation to compensate for the power failure.
maintenance of a UPS has a coup.Les bateries are not eternal.
