PRODUCT DESCRIPTION

Product Description
Inverter power supply is designed specifically for power and communication systems. It is a conversion device that converts the electrical energy of the mains and batteries into uninterrupted and purified AC power, providing continuous AC power for computers and other electrical equipment to prepare for the instability and power outage of the mains. It can also prevent various distortions of public power, such as voltage drop, surge voltage, peak voltage, and broadcast frequency interference.

Protection functions:
Input undervoltage, Input overvoltage protection, High temperature protection, Output overload protection, Output short circuit protection.
Operating Principle

DC power supply mode:

Inverter mode, where the DC boost inverter is switched to the output through a static switch and powered directly by the battery or DC. When the inverter fails, it automatically switches to the bypass and is powered by the mains to ensure uninterrupted power supply for the equipment.

Bypass power supply mode:

When the inverter experiences abnormal conditions, such as abnormal input voltage, host overheating, short circuit, abnormal output voltage, or load exceeding the inverter's bearing range, the inverter will automatically stop running to prevent damage. At this time, the static switch will be powered by the bypass power supply output to the load for use.

Maintenance bypass power supply mode:

When the inverter equipment needs maintenance or repair, the inverter switches to bypass operation with the DC input disconnected, and then manually switches to the "maintenance bypass switch" to ensure continuous power supply to the load during maintenance or repair.
Technical Features

7
Support RS485 communication function, use monitoring software to real-time understand the working status of the power supply;
8
Adopting intelligent control, equipment operation does not require strict program settings;
9
It has a comprehensive safety protection system that provides input anti reverse, buffering, output short circuit, overload, internal overheating, input and output high and low voltage protection functions to ensure the overall reliability of product operation stability.
10
Main power supply type and battery main supply type: The dip switch can be selected. 
A) Main supply type of mains power: 
When there is mains power, it is at the output of mains power, and automatically switches to inverter output when there is a fault in mains power input;
B) Battery main supply type: 
When there is mains power, it is in inverter output, and automatically switches to mains power output when there is a DC input fault;
11
Provide three sets of passive dry nodes, respectively for DC faults, inverter faults, and mains faults;
12
Supports no DC power on function and can operate in a state of only mains power. This feature allows the inverter power supply to be put into use first, and then the battery can be installed.
