KKmoon 500W Inverter Boost Board Transformer Power DC 12V TO AC 220V 380V Car Converter

Features:
The product features high energy efficiency, long service life and low power consumption, convenient and safe to use.
This product is widely used. It is a good helper for camp, night market vendors and power failure emergency.
Can be used as a front-stage boost inverter circuit for pure sine wave, modified sine wave, single silicon machine, four-silicon machine.
For electronic enthusiasts DIY project, maintenance, factory control cabinet and so on.
note:
This board is a high-frequency square wave AC output, not suitable for general inductive appliances, such as: motor, electric fan, coil transformer, etc.
Might not work for simple resistance-capacitance step-down small electrical appliances, cheap resistance-capacitance step-down LED lamps.
When connecting to a small load (LED lights, mobile phone charger, DVD set-top box, etc.), it is recommended to connect to low output voltage such as: 160V.
It is recommended to increase the heat sink when working for a long time.
The power supply cannot be reversed. The power supply and power line require large enough current.
Because there is no protection, do not overload or short circuit.
Many general multimeters can not measure output high-frequency square wave AC voltage or show low or high. (It is not correct, not actual voltage)
