WATTSTUNDE® NVS Changeover Station 16 A Mains Priority Switch
WATTSTUNDE® WS16ANVS Mains Priority Switch – Automatic Transfer Switch for Inverters & Shore Power
The WATTSTUNDE® WS16ANVS Mains Priority Switch enables safe operation of an inverter and a 230 V AC mains within the same circuit. It automatically switches between power sources and reliably protects the inverter from external voltage.
Automatic Switching with Protection Function
As soon as an external 230 V AC mains is present, the WS16ANVS automatically switches to this source. If the mains is disconnected, the inverter takes over the supply again.
