Usage 1: The only way the power of the fire load in the facility or a motor, fan to provide a variable frequency three-phase emergency power system to address the emergency power supply and start the motor during the course of the impact of power supply equipment. Such as: water pumps, fan motors electric motors or other devices. 
 2, the installation forms: floor-standing 
 3, standby time: 90 minutes (can be configured safety design requirements for standby time) 
 4, series of specifications: 2.2KW-400KW 
 Second, product characteristics: 
 1, the emergency power supply - when the commercial power interruption or voltage outside the specified range automatically provide 380V, 50Hz three-phase emergency power to ensure the normal operation of important loads. 
 2, high-performance - using SPWM high frequency inverter technology, high quality power supply to meet a variety of loads. 
 3, high reliability - the use of advanced technology and redundant design, is CPU control, and manufacturing of high quality imported components, stable and reliable. 
 4, the protection of sound - with excellent output overload, short circuit, over discharge protection. 
 5, user-friendly working conditions-LCD display, mains voltage, output voltage, current, frequency, fault and other information, clarity; sound and light failure alarm indication. 
 6, the charging capability - a machine built using controlled charging technology, fast charging, float voltage stability. 
 7, Structure Overview - the machine features a modular design, simple structure and easy maintenance. 
 8, remote monitoring - remote computer can be realized EPS centralized monitoring and management 
 9, intelligent battery management - intelligent battery monitoring and management components, to enhance the battery monitoring, battery life, and utilization. 
 10, the output waveform is a modulated wave, the output only after a circuit breaker or AC contactors and thermal relays, etc. The main contact to the load: EPS output to the load to pass between the distribution box with auxiliary power supply, we must also AC220V or DC24V plus the auxiliary power supply, load up and running is also need to provide a passive EPS normally open signal as the feedback signal. (Supporting the use of contacts and exchanges)
