What is the power of the dual power supply load?220V single-phase electricity, 63A current can load 12KW.5. Can this product be powered off or switched off?This product is a two-stage dual power supply, with no opening position, that is, there is always one power supply connected to the load, so it cannot be opened and powered off.6. Does it have short circuit/overload protection?This product is a PC-level dual power supply, without short-circuit protection and overload protection.7. Which channel of the main and backup power supply will give priority to power supply?When the two circuits are powered at the same time, the main power supply will give priority to power supply.
