Loading...
Critical loads stay supplied when the grid fails.
Grid-to-island transfer
≤ 20 ms in total, with PRIME-APCS
Switching
Semiconductor, no mechanical delay
Reconnection
Synchronized, without interrupting loads
Sizing
Rated for the critical load of the site
Discover how one switch keeps critical loads running through grid faults and brings them back without a restart.
Semiconductor switching separates the site from a faulty grid, and PRIME-APCS takes over the loads in grid-forming mode.
Watches the grid at all times and detects loss of voltage, dips, and frequency and phase deviations.
Closes only after voltage, frequency and phase are matched, so the loads go back to the grid without interruption.
Keeps critical feeders supplied and separates non-critical feeders when needed.
Coordinates with grid protection and anti-islanding requirements at the connection point.
A built-in bypass for maintenance of the switch.
Rated for the critical load of the site and matched to the power of PRIME-APCS, with total grid-toisland transfer within 20 ms.
