This sine wave inverter needs multi-layer protection design
Public Group active 2 years, 10 months agoIs not rapid expansion of alternative fuels the energy storage power market, sine wave inverters are traditional in outdoor activities, mobile office, field camping, medical rescue, vehicle tool power supply, etc., to meet various power shortage will need.
It turns out that the sine wave inverter needs these protective designs staying safer:
The short-circuit protection function refers to the protection quit blogging . . ensure that the power supply is shortened quickly and reliably after a short-circuit fault occurs within the electrical circuit, so related to avoid damage to the electrical equipment caused by the impact of the short-circuit current.
The over-current protection function means how the device features a current protection module. When the current exceeds the set current, unit will automatically power on to protect the device. For example, the USB interface of your motherboard CPU generally has USB overcurrent protection to protect the motherboard from being burned.
Over-power protection function, once the load is over-voltage all of the power supply, or the subsequent load has short-circuit over-current and other super-real power faults, the overload protection circuit regarding circuit reduces the main power supply through the feedback circuit action preserve the circuit and load. Make the fault no longer expand.
Under-voltage protection function Once the line voltage drops on the critical voltage, the action of protecting electrical appliances is called under-voltage insurance policy coverage. Its main task is to stop the equipment from being burned due to overload.
The over-temperature protection function means following the temperature exceeds the flip threshold, the potential of the negative terminal of the comparator will drop to be lower versus the potential VREF2 of good terminal, and the comparator will output a high level, thereby turning from the power switching device and preventing the chip from being ripped.
Overcharge protection function. If not in normal use, we also need to charge the car’s emergency starter energy. When the power supply is fully charged and also the circuit will never be cut off, the power supply will automatically activate the overcharge protection function and no longer pre-charge. Play the role of protecting the battery and prolonging the use of the product.Car Inverter Truck Quotes
