The 123PowerSwitch is a bidirectional solid state relay with very low power consumption when turned on. This will ensure that it can operate for a very long time, even if the battery is almost empty. A second benefit is that it can switch bidirectional currents. This means that it can be used with devices which both can charge and discharge, like a combined charger/inverter.

The status LED gives information about the operation of the 123PowerSwitch. -When the LED does not flash, the 123PowerSwitch does not get any power from the two control wires. In that case, the relay does not conduct (open state). -When the LED flashes 1x per five seconds, the relay is conducting (closed state). -When the LED flashes fast several times and after this no flashing for 5 seconds, the relay is too warm and it will not conduct (open state). When the relay has cooled down, operation will restart.
Parallel operation Up to three 123PowerSwitch units can be connected in parallel to increase the current switching. Give all power cables to each PowerSwitch about the same length to distribute the total current evenly over the units and add a fuse (max 125A) for every PowerSwitch.
