Product Description
Product Overview:
SJR3-2000 series is the latest soft starter developed by our factory. It expands new functions such as literal display, industrial communication and various protections based on the products of SJR2 series. This product will be the upgrading and replacement of SJR2 series eventually. It shares the same technical framework with SJR3-3000.
The applicable standards:IEC 60947-2-2:2002
Product Features:
(1) Easy to control: support a variety of communication protocols; operation panel can be used outside ; programmable output; 4-20mA DC analog output.
(2) Long life:compared to intense heating, heavy harmonic pollution and high module consumption caused by online module, this type of soft starter has a longer using life and more safety.
(3) Liquid crystal display: this display is more intuitive and convenient.
(4) No need for control circuitry: it greatly slashes the material cost.
(5) Space saving: compared with star-delta starter and self coupling decompression starter, the built-in bypass greatly reduces space requirement for the cabinet, so the user can arrange the electrical equipment in higher density, thereby reducing the cost.
(6) Labor saving: compared with star-delta starter and self coupling decompression starter, greatly cut down the design and installation time for no need of deploying line circuitry.
