AC power supply panel

 AC POWER SUPPLY PANEL:

Microcomputer type ac (inverter) power supply panel using dual power switching device communication into line, have online, zero conversion function. Like the way power anomalies between the power switch, ensure the reliability of the power supply. When the mains normal, single-phase 220 v ac (or three-phase 380 v) after isolation, rectifier filter to inverter power supply, if the ac input power, the power system dc screen after counter-attack diode to inverter power supply, and by the output isolation to important load power supply; If the dc screen without electricity, it is still the ac input power supply; If the inverter overload or fault, the static switch to bypass the power supply.System characteristics- the power supply quality improvement. Through the input/output double isolation and double transformation work mode, make its output voltage frequency stability become standard sine wave waveform.- has the mains power down protection function, if the input power supply, inverter power by power system dc panel power supply (DC110V / 220 v), load power supply without interruption.- effectively restrain noise. Due to the use of isolation transformer and communication - dc - ac mapping mode, effectively filter input power of the clutter, make the load get pure sine wave power supply.- internal installation check diode, can prevent the dc bus voltage than dc input side high voltage to the dc screen protection against irrigation, the role of the dc panel.- ac bus and dc bus isolation. Completely shielding ac bus and influence each other between the dc bus.- have complete delay soft start function, can greatly reduce the system startup process to the equipment and the impact of the power grid.- has a variety of warning method, through the sound, light, LCD, input/output contact and communication way for current happened to alarm in a timely, accurate and detailed hint, to improve the reliability of the system at the same time, help to maintain personnel accurately and rapidly positioning and debugging.- with input reverse connect, under voltage, over voltage, output overload, short circuit, overheating protection function.- equipped with RS232/485 communication interface, and PC communication, realize "four control" unattended.
