1 Ph Soft Starter 1.5kW for pumps application


Recommended Posts

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,

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.lmphotonics.com/store/product_i.../products_id/51


Best regards,
