Feature: 1. SUPERIOR PERFORMANCE: High frequency inverter board with high energy efficiency, long life, low power consumption, easy and safe to use, energy efficient and durable. 2. MULTIPURPOSE: The inverter module can be used as a pure sine wave, modified sine wave, single silicon or four silicon pre stage inverter circuit. 3. PRACTICAL ACCESSORY: The inverter board is suitable for DIY production, repair and replacement for electronic hobbyists, as well as for manufacturers' control cabinets. 4. WIDE OCCASSION: High frequency inverter board is a good helper for wilderness, night camps, night market stalls and driving families. 5. APPLICABLE: inverter module can be used for lamps, non‑inductive household appliances, small rice cookers, energy saving lamps, soldering, switching power supplies, etc. Specification: Item Type: Inverter Board Material: Metal, PCB Power: 1000W Output Voltage: Multi Level Voltage V0-V1=220V V0-V2=330V V0-V3=380V V0-V4=420V V1-V2=110V V1-V3=160V V1-V4=200V V2-V3=50V V2-V4=110V V5=18V Static No Load Current: Approx. 0.35A Output Frequency Waveform: Approx. 20KHZ High Frequency Quadrate Wave Protection: No Protection. Package List: 1 x Inverter Board Note: 1. This board is a high frequency quadrate wave AC output, which cannot be carried by general induction appliances. "Such as: motors, electric fans, coil transformers, etc. can not be used directly".2. simple resistive buck small electrical appliances, cheap resistive buck LED lights may not be used.3. Consideration should be given to the fact that the power supply should not be at full load for a long period of time when in use. If it needs to work continuously for a long time, it is recommended to run at 80 percent efficiency.4. Allow space for use to ensure that the power supply can work for long periods of time, otherwise it may cause artificial early failure.5. The load is an electronic switching power supply product. We need a high frequency diode output on our board. Because the rectifier part of many switching power supply appliances is a normal rectifier tube to save costs, connecting it to the "high frequency AC output" will cause the rectifier diode of the original appliance to heat up quickly and damage it, and the diode will break through the circuit. Eventually, the inverter board will burn out.
