FEATURES:
1, OONO F-1073 Three Source automatic transfer switch, AC 230V versions, with a maximum load current of 20 amps. Select input source automatically or manually. With output on/off control function. With power-off memory function.
2, In automatic mode (press the AUTO button), the automatic selection priorities are: 1 - Inverter, 2 - Utility, 3 - Generator. If you want to manually select an input source (manual mode), you can directly press button: Inverter / Utility / Generator. When you want to return to automatic mode, just click the AUTO button. (Taking the inverter as the highest priority input source is to better utilize the green energy of solar panels).
3, Output on/off control function: When you want to disconnect the load power, just click the ON/OFF button, it will immediately disconnect the live wire and the neutral wire at the same time.
4, Multiple indicator lights allow you to clearly see the product's input source status, output status, operating mode, and the status of the internal relay switch.
5, It has a power-off memory function, and the next time it is powered on, it will return to the state before the power-off, which will not cause unpredictable consequences. The memory includes the operating mode, input source, and output switch status.
6, Transfer time less than 30mS (0.03 second), for most smart devices or computers, the switching action of 30mS time will not affect their normal operation.
7, The live wire and neutral wire of each input source are controlled by different high-power SPST relays, ensuring that there will be no power arcing and no creepage between different input sources. The design is specially optimized to not cause your GFCI protector to trip for no reason.
