Fields of application
PILLER APOTRANS AT 25–63 A – low-current four-pole three-phase static transfer switches (STS) that automatically switch critical loads to a backup source if the main source deviates from the norm or disappears. Designed for server rooms, distribution cabinets and critical IT equipment where a backup source is required up to the load.
Features:
Four-pole three-phase switching, safely switches the neutral as well
Fuse-free: large thyristors with high short-circuit resistance
Switching time typically within 3 ms per phase
Fully redundant monitored electronics, thyristors monitored in all operating modes
Natural air cooling, low noise, high efficiency
Integrated manual bypass and quick-change components
Adjustable operating criteria, event memory, convenient control panel
Remote monitoring, integration with building management system, three housing options
