Product Details

The lowest price of whole network for 3phase AC Motor Power Soft Starter 132kw

Product Description

BZ1S series AC motos intelligent soft starter is a new type of advanced starting device which involves electronic technology,microcontroller and advanced control technology.The soft starter can limit the starting current effectively at the start of asynchronous motos,and can be used on fans,water pumps and heavy load machines like conveyers and compress ors.It is the ideal replacement for voltage-limiting starting equipments like star-delta transformer and auto-induction voltage limiter.Meanwhile,the soft starter has various control modes that allow it to be controlled by keyboard,external terminals or host computer,and multiple outputs including fault relay outputs,multi-function relay outputs and analogue outputs,which facilitate its usage in various systems.
