Sterling Power AC32A Automatic Crossover Switch, 32A 110-230V AC

The Sterling Power AC32A (Pro Switch) is a 32 amp automatic AC transfer switch for boats, RVs and specialty vehicles with up to three AC sources such as shore power, a generator and an inverter. It comes with a remote control panel on a 10 m cable.

Channel 1 has top priority, then channel 2, then channel 3, so plugging in shore power automatically takes over from the inverter. The switch draws its control power from the AC sources themselves rather than the DC system, so it still works with flat batteries, and it waits 0.25 seconds between breaking and making to protect sensitive equipment. A lock-out relay can keep heavy loads like a water heater or battery charger off while the inverter is supplying power.

Features

• Internal switch breaks both live and neutral, with a 0.25 s changeover delay
• Powered from each AC input, not from the batteries
• Sequential priority switching across 3 channels
• Lock-out relay to drop selected loads when running on the inverter
• Remote shows the active source, available sources and faults
• Reverse polarity indication on the shore input
• 6 internal fuses, fusing both live and neutral
• Remote on/off for the priority (shore) circuit
• 10-second delay on the generator input to let it start up
• Handles 110V, 230V or a mix of both
