Splitting up loads

Each relay can switch up to 120A depending on the voltage of the load. If the total current exceeds

this 120A, it may be possible to split up the load in multiple smaller loads. If it is possible to split up

the load into smaller <120A loads, both relays on the SmartRelay or even multiple SmartRelays can

be used.

Example

An application has a nominal voltage of 12V, the total load is 150A. Connected are two inverters,

both 75A. One inverter is used for the sockets, water kettle and lightning, the other inverter for the

water heater (900W).

Connect input1 to input2 of the SmartRelay. Relay 2 will now always be in the same state as relay 1.

Relay 1 can be used to switch the power of inverter 1, relay 2 can be used to inverter 2.

Do not connect both poles of relay1 to the poles of relay2 trying to "increase the maximum

current". Contacts in relays will never close at exactly the same time. Thus the total current will

always be switched on or off in one relay.
