How it works: The 240V AC input is converted to multiple 12V DC outputs (9 or 17) with a total current output of 10 or 20 Amps, depending on the model. The 9 channel model has 8 ports fused at 2A each plus 1 port fused at 4A and can supply a total load of 10A. The 17 channel model has 16 ports fused at 2A each and also the extra 4A port, and can supply a total load of 20A.
The green LED lights show that your channels are working. If a channel is overloaded the green light goes out. But a clever PTC self-resetting fuse, on each port, prevents full system overload by disconnecting only the overloaded channel. Once the load is removed, the fuse resets and the port becomes immediately useable again.
