1.3 Function introduction

1 Basic principle and structure 1.1 Working principle block diagram of single module Figure 1-1 Working principle block diagram Note:

The equipment without charging does not include the function of dotted line 1.2 Working principle The power supply is a standard 19 inch rack type product, which is composed of 2~5 3kVA inverter modules in parallel, with an output capacity of 6~15KVA.The machine is mainly composed of common choke filter, backflow noise absorber, high-frequency boost circuit, PWM sinusoidal inverter control, AC input filter,ECO switching device, output AC filter and communication detection display interface.When the mains power is normal, ECO directly outputs the load to optimize the efficiency;In case of mains power failure and 48VDC DC power supply circuit, after signal preprocessing of DC voltage through common choke filter and back pouring noise absorber, it is sent to high-frequency boost circuit for DC input boost, and then participate in high-frequency PWM inverter circuit inversion to output 220VAC voltage, which is sent to load equipment after filtering,The communication detection display interface detects and controls the running state and working parameters of the machine and displays them through the LCD panel.

At the same time, the power supply has battery overvoltage and undervoltage protection, output overvoltage protection, output undervoltage alarm, output short circuit, over temperature and other protection functions.The information can be reported through RS485 communication.Power supply equipment is specially designed for communication and can be used in office, power, industrial control, security and other fields. 1.3 Function introduction 1) Self starting function.When the DC input is greater than 48 ± 1V (the equipment is not charged) or connected to the mains power (the equipment is charged), the power supply equipment starts automatically.

If there is no mains power or the mains power is abnormal, the panel indicator flashes, and 4
