Description

SR-YJF/SR-YJSF Series (Fast switching) Emergency Power Supply, Can be used as fire facilities, power electronics and a variety of high-strength discharge lamp (such as high pressure sodium lamp, metal halogen lamps) and other emergency equipments.
Applied to the Military, Hospitals, Schools, Governments, Shopping malls, Squares, Railway stations, Docks, Subways, Factories, Parks, Tunnels, Convention centers, Financial institutions and other fields. 

Principle of Work
● When electricity is normal, city electricity supply to the load device, at the same time, the intelligent charger to charge spare batteries;
● When the city electricity power failure, or more than normal voltage, the controller sends inverter signal and start the inverter, which immediately switches device, continues to provide the sine wave AC;
● When the output voltage of city electricity is normal, emergency power supply will automatically switch to city electricity power supply. 

Features

● Large screen LED menu display, friendly interface, easy operation;

● CPU with embedded chips, pure sine wave output, high integration, strong anti-interference ability, high running speed;
● Modular design, easy maintenance;
● With perceptual load and mixed load

● With self-detection, high intelligence, convenience, reduced fault output;
● Dual power supply with automatic switching function, high reliability;
● With over voltage, under voltage, over temperature, over current, short-circuit protection and sound and light alarm functions;

● Intelligent battery charge and discharge management and temperature compensation function, automatic battery discharge protection, prolong battery life, ensure the battery work in the best condition;
● With fire linkage, through the RS232/RS485 communication interface can communicate with the host computer, to achieve the "four remotes".
