1. This board is high-frequency square wave AC output, so it can not be carried by general inductive appliances (motor, fan coil transformer, etc.)2. When connecting to a small load (LED light, mobile phone charger, DVD player, J top box, etc.), it is recommended to connect the gear with low output voltage, such as 172V or 200V3. It is recommended to increase the heat sink when working for a long time with load ( 100W),4. The power supply should not be connected in the opposite direction. In addition, the power supply and power line should have enough current. The output should not be overloaded or short-circuited.5 When the high-frequency no-load voltage is output, the measurement with a multimeter will show a high voltage (incorrect, not the actual voltage)Product parametersPower: 50-150WInput: DC12VOutput: 220VQuiescent current: about 0.05AOutput waveform: high-frequency square waveOutput frequency: about 20KHzProtection: no protectionWeight: 64.1gwith the size of 3 x 10cm, which is mainly used for the front stage of electronic DIY inverter.When the high-frequency no-load voltage is output, the measurement with a multimeter will show a high voltage (incorrect, not the actual voltage)The default output wiring is as follows: "For reference only"V0--V2=110VV0--V3=175VV0--V4=200VV0--V5=220VV5--V4=20VV5--V3=45VV5--V2=110VV4--V3=28VV4--V2=90VV3--V2=62VDifferent batches of different colors may be different without affecting the usecolor: blueMaterial: pcbPackage Contents:1 x converterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
