Description

Features: 1. High energy efficiency, long life, low power consumption, convenient and safe to use, energy saving and durable, widely used in the field, night camps, night market vendors, driving and family power outage emergency helpers 2. It can be used as the front-stage boost inverter circuit of pure sine wave, modified sine wave, single-silicon machine, and four-silicon machine. For electronic enthusiasts DIY production, maintenance and replacement, manufacturers control cabinet supporting products and so on. 3. You can use electrical appliances: lamps, non-inductive household appliances, small rice cookers, (note: support all "electronic products") such as: energy-saving lamps\solder\switching power supply\satellite TV receiver\bulb\LED light \LED energy-saving lamp\fluorescent lamp\DVD player\VCD player\EVD player\LCD TV\color screen TV\flat screen TV\notebook\computer\various computer monitors\all electronic charger products\etc. The main parameters: Power: 1000W Input: DC12V Output: AC 0-220V-330V-380V-420V and AC18V Static no-load current: about 0.35A Output frequency waveform: about 20KHZ high frequency square wave Protection: no protection Notice:  1. This board is a high-frequency square wave AC output, so general inductive appliances cannot be carried! ! (Such as: electric motors, electric fans, coil transformers, etc. cannot be used directly) Another: Simple resistance-capacitance step-down small electrical appliances, cheap resistance-capacitance step-down LED lamps, etc. may not be used 2. Many multimeters that output high-frequency square-wave AC voltage cannot measure or display low and high levels (it is incorrect, not the actual voltage) (can be measured by the multimeter in DC mode after rectification) 3. When in use, it is necessary to consider that the power supply should not be in a full-load working state for a long time. If you need to work continuously for a long time, it is recommended to operate at 80% efficiency. Leave room for use to ensure that the power supply can work for a long time, otherwise it may cause artificial early failure. To Special reminder: The load is an electronic switching power supply product that requires a series of high-frequency diodes on our board. Because the rectification part of many switching power supplies uses ordinary rectifiers in order to save costs, so when connected to the "high-frequency AC output", it will be conductive. The rectifier diode of the original electrical appliance was damaged by rapid heating, and the diode broke down the circuit. Eventually cause the inverter board to burn out.
