A.C. Power Supply
Low-voltage installation static transfer switch-sts
Application
Оrganization of no-break power responsible and especially responsible consumer.
Used in
- – electric motors of responsible technical processes, critical to interruptions in power supply;
- – computer science;
- – communication engineering, supervisory controls;
- – ensuring working lamps of street lighting or another load.
Advantages
- – high perfomance: 2 ÷ 5 ms;
- – high reliability of power supply;
- – big resource of switchings;
- – control system builds on a programmable controller Siemens Simatic S7 – 1200;
- – comfortable interface of operator builds on touch coloured pad;
- – authority of magazine evidence, connection with Automation System Control upper level;
- – interface of connection: RS 485, Ethernet;
- – protocol of data exchange: Profibus, ModBus, TCP/IP.
