AC Power Supply use for our work life usually brought greater convenience, in terms of home appliance manufacturing, electronics technology, military equipment, laboratory tests have wider application. One can imagine that if out of the use of variable frequency power supply, or the use of variable frequency power supply is not correct, it will probably give us greater operating life is not convenient. Now in order to facilitate broad use of variable frequency power users, Changzhou Cayenne to introduce electronic communication frequency power use precautions. 1, regular maintenance communicate regularly view the fan power requirements and adjust the system parameters of the working conditions of communication power inverter, dust inside the machine also needs timed eradicated. 2, communication in the use of variable frequency power supply, be sure to abide by the instructions of demand for goods, to ensure that the connected front, the zero line, ground fit all fit specifications, are not free to alter the order of one another. There are for example three-phase inverter power communication problems need to pay attention to the phase sequence, phase sequence will show the fault or alarm, other brands as well. 3, put an end to the use of communication power inverter overload. Communication power inverter best controlled within 80% of the maximum motor load. Upon verification of the results show: the vast majority of communication frequency power load control in 30% to 60% of the additional output power range is the best way to work. When prevent overloading the use, in the inverter state, the breakdown of the inverter transistor unnecessary losses. 4, communication power inverter stop frequently closed and opened, after closing the communication power inverter, wait at least 6 seconds to open communication frequency power again. Otherwise, communication and power inverter frequency power may enter into the communication neither electricity output, the inverter output nor "launch failure" status. 5, should prevent direct sunlight and ventilation outstanding place to place communication frequency power. 6, in strict accordance with accurate open, shut down the order to operate, to prevent the communication due to a sudden power inverter plus perhaps lighten the load, the device supply voltage output shaken, causing a communication power inverter endangering. Only in this way truly understand the use of AC variable frequency power supply in order to better use the AC variable frequency power supply. http://www.kayandz.com High frequency power supplies, DC power supplies, DC power supply manufacturers http://www.agjixie.com shears, shears, tilting hydraulic shears http: // www .hhnhj.com vacuum kneading machine, kneading machine, ordinary kneading machine
