Dear all.
I work in a campany producing electropumps.

I am interested in information regarding low power (1,5kW) soft starter for single phase pump application.

In the marketplace there are a lot of VSD controller for pump for constant pressure application that in addition to the close loop pressure control deliver the function of soft start and soft stop.

What I am investigating is the possiblity to realise a cheper soft starter for the low power size pump with a simply (SCR?)circuit in accordance with CE, C-Tick approval.

Could someone provide me usful information?
Somebody could provide me an electronic schematic?
Did you have an idea about a cost indication?

Thanks in advance for your kind reply,
bobo73;p;

Hello Bob73

Welcome to the forum.

There are soft starters available for single phase motors. Thes operate at fixed speed only. You can not vary the speed of a single phase motor with a soft starter.

See http://www.motor-control.co.nz and http://www.lmphotoni.../products_id/51

Best regards,
