Technical principle：
The embedded installation design supports the 19 inch standard rack type installation mode and the mobile portable box installation mode;
It adopts CPU control, the circuit is simple and reliable; the intelligent switch machine has high degree of automation and convenient operation;
The PWM technology is adopted, and the output is pure sine wave with stable frequency, noise filtering and low distortion;
The interface is friendly and LCD is used to display: the working status, mains voltage, output voltage, battery voltage, frequency, load power, etc. are clear and clear; there are sound and light fault alarm, fault indication and other functions.
It is divided into main power supply type, battery main supply type and pure reverse type:
A) Main power supply type: when there is mains power, it is in the mains output, when the mains power input fails, it will automatically switch to the inverter output;
B) Battery main supply type: when the battery is normal, it is in the inverter output, when the DC input fault, it automatically switches to the mains output;
C) Pure inverse type: no AC power supply, pure inverter work, support long time load inverter work;
It is allowed to cut off the DC in the startup state and automatically switch to the municipal power bypass, which does not affect the power supply of the load, and is convenient for the maintenance and replacement of the battery;
If the battery voltage is too high or too low, the inverter power supply will turn off the output. If the battery voltage returns to normal, the power supply will automatically restore the output;
Supporting communication function (RS485 communication interface mode or customized other interfaces)
RS485: Standard Modbus communication protocol, RS485 communication interface, RJ45 crystal port from left, 1 pin 485a, 2 pin 485b
Other communication interface modes can be customized as required
It supports the function of no DC power on, and can operate in the state of power supply only. This function allows the inverter to be put into use first, and then install the battery. (the machine with parallel mode must be started by DC)
The container shell of mechanical and electrical unit is made of metal material, and meets the requirements of vibration resistance and service life of inverter power supply when moving in various environments;
