Automatic transfer switch ATICS®-…-ISO

manualpanel-mountemergency power supply

Overview
ATICS®-…-ISO transfer switching devices provide automatic changeover between two independent power supplies and continuous monitoring of unearthed (IT) power systems. The power section and control electronics are integrated in one flat, compact enclosure for space-saving installation in control cabinets and reduced wiring complexity. The device is designed according to functional safety requirements (SIL 2).

Key features

• Integrated switch-disconnector and IT-system monitoring in a single unit
• Designed for safety power supplies with functional safety SIL 2 (EN 61508)
• Compact, flat enclosure for control-cabinet mounting
• Plug connectors on all wiring and optional bypass switch for testing and replacement without power interruption
• Manual on-device operation and mechanical locking
• Communication and parameterisation options for monitoring and configuration

Installation and commissioning

• Space-saving design simplifies retrofit and new installations
• Reduced wiring effort and faster commissioning

Safe operation

• Robust switch-disconnector contacts
• Mechanical interlock and local manual operation
• Certified to EN 61508 SIL 2 (TÜV SÜD)

Uninterrupted maintenance

• Plug connectors and optional bypass switch enable testing and servicing without interrupting the supply

Applications

• Suitable for safety-critical environments such as Group 2 medical locations (operating theatres, intensive care) where redundant supplies and unearthed (IT) system monitoring increase operational safety and availability.
