Feature: 1. The conversion voltage is converted from DC 12V to AC 110V/220V, and the output waveform is a frequency square wave. 2. Using high-quality PCB board, this inverter module is very durable after long time use. 3. This inverter module is mainly used in the inverter stage before electronic DIY work. 4. This inverter module is used in night market vendors, driving, household power outages, etc. 5. With small in size and light in weight, this inverter module is very easy to install. Specification: Item Type: 150W Boost Inverter Material: PCB Purpose: Mainly used in the inverter stage before electronic DIY work; and used in night market hawkers, driving, household power outages, etc. Power: 150W Input: DC12V Output: AC 0-110V-172V-200V-220V Quiescent Current: About 0.05A Output Waveform: High frequency square wave Output Frequency: About 20KHz Protection: No protection The Output Wiring Voltage as Follows: V0--V2=110V V0--V3=175V V0--V4=200V V0--V5=220V V5--V4=20V V5--V3=45V V5--V2=110V V4--V3=28V V4--V2=90V V3--V2=62V. Package List: 1 x Module Note: 1. This board is a high‑frequency square wave AC output, so general inductive appliances cannot carry "motors, fans, coils, transformers, etc."2. When connecting to a small load (LED lights, mobile phone chargers, DVD set‑top boxes, etc.), it is recommended to connect to a gear with a low output voltage, such as 172V 110V or lower.3. It is recommended to increase the heat sink to work for a long time under heavy load (≥100W),4. The power supply cannot be reversed. In addition, the power supply and the power cord should have enough current5. Do not overload the output and do not short‑circuit.6. The output high frequency no‑load voltage multimeter measurement will show high (it is incorrect, not the actual voltage)Special reminder: For electronic products, it’s best to connect a high‑frequency diode to the output of our board to rectify it into a DC output, because the rectification part of many switching power supplies uses ordinary rectifiers in order to save costs, so it is connected to the "high‑frequency AC "Output" will cause the rectifier diode of the conductor to heat up and damage it, and the diode will break down. Eventually cause the board to burn out.
