Mains switching, mains priority circuit 16A, 230V

Mains switching, mains priority circuit 16A, 230V
Switching capacity 12 amps for inverters up to 3680 watts
 
Protects the inverter from damage when several 230V sources are operated in one circuit

Vehicle, car, boat, camping, outdoor, caravan, motorhome, solar

Application example: An inverter is permanently installed in a motorhome and supplies the motorhome's internal 230V loads. If a second 230 volt mains supply from a generator or the public grid (e.g. at a campsite) is now fed into the motorhome via the external socket without the inverter having been disconnected on the mains side first, the external voltage (from the generator or the public grid) reaches the inverter output. This inevitably leads to damage and high repair costs for the inverter. To avoid this, we strongly recommend using a mains priority circuit.

Automatic disconnection of the inverter from the 230V mains:

The switchover unit automatically detects when a second mains voltage (from shore power or a generator) is present and uses a double relay circuit to disconnect the inverter output from the internal power network. This ensures that the different voltage sources never meet. Only one 230V source at a time is switched through to the loads.

Switchover between the voltage sources takes about 0.5 seconds, which allows the transfer switch to be used with an inverter as a nearly uninterruptible power supply (UPS). Note that the connected loads will briefly switch off during the changeover.

You can choose which voltage source is connected to master and which to slave. The inverter can therefore also be set as master, and the slave source (generator or public grid) is only switched through when the inverter is not available.

Please note that, according to the manufacturer's specifications, the input voltage at the master input should be a pure sine wave.

Switching back to inverter operation:

The switchover unit automatically detects as soon as a second mains voltage (from the public grid or a generator) is no longer present and switches the inverter output through again. All connected 230 volt loads are then supplied by the inverter again.
