Automatic changeover switch ATICS®-…-DIO

manualDIN railcompact

Overview
The ATICS®-…-DIO transfer switching devices perform controlled changeover between two independent power supplies. Integration of the power switching unit and the control electronics in a single compact device reduces switchgear space, simplifies wiring and reduces potential fault sources. The product is designed according to functional safety guidelines (SIL 2).

Service & maintenance
Plug-in connectors on all connection leads and the optional bypass switch enable testing, repair or replacement during ongoing operation without interrupting the power supply. This supports continuous availability and reduces service-related downtime.

Features

• Space-saving installation and retrofit: all-in-one design combining switch-disconnector and control electronics
• Available in 2-pole and 4-pole versions with rated currents from AC 63 A to AC 160 A
• Functional safety SIL 2; certification by TÜV SÜD
• Manual operation on the device and mechanical interlock
• Plug connectors and optional bypass switch for uninterrupted maintenance
• Communication and parameterisation options for monitoring and service

Applications

• Redundant supply switching for data centres, industrial installations and medical locations (group 2) where continuous, reliable power is required even in fault conditions
