· A detailed description. Overview of the company's intelligent ?????????? EPS emergency power system consists of a rectifier, static switch module / manual bypass switch, a control unit and inverter, racks, battery, of which the inverse change is the core. The role of AC rectifier is converted into direct current, battery charging realize eps and power to the inverter module;? Inverters convert direct current into alternating current role sucked, stable and sustainable supply of electricity load equipment; static switch can be set system works in two ways to backup or online, and adjust the inverter? output and mains synchronization, ensure that the load between the mains and the inverter output is switched smoothly. Manual bypass switch can switch the load to mains and isolated from the system, so that when the system does not interfere with the load equipment maintenance? Work properly. Monitor real-time monitoring of the entire system, and an alarm signal, the power supply system of the machine monitoring. ? · Two. Using the occasion ?? AC mains break all kinds of emergency power load level and is particularly important, such as the supply of various types of critical computer systems; secure supply hospitals, hotels, shopping malls, etc;; supply all types of construction work and fire-powered transportation system, highways, tunnels, subways, light, electricity civilian airports; power supply of the power system; supply of various types that can not cut production, laboratory equipment. Is a pure sine wave devices require high quality power supply. Three. Technical parameters? Model 2.2 ~ 500KW input voltage 380V ± 20% Three-phase four-wire + PE Frequency (Hz) 50Hz ± 5% output capacity 2.2KW ~ 800KW voltage 380VAC three phase four wire + PE voltage stability ± 5% ( emergency power) sine wave harmonic distortion: ≤3% frequency 50Hz ± 0.5% overload capacity of 120% uptime conversion time of ≤0.1 seconds (mains supply into the emergency power supply time; if used with a metal halide lamp switch time can be less than 0.006 seconds) Battery Maintenance-free sealed battery backup time 60 minutes / 90 minutes / 120 minutes / (according to design requirements to configure an alternate time) protection Short circuit protection, overcurrent protection, phase can run efficiency of emergency when LCD display: more than 90%; normal: close to 100% Operating temperature: -24 ℃ ~ 40 ℃ Relative humidity: 0 to 90% Altitude: 2000 meters adapt to the load of the power supply is especially suitable for inductive and capacitive mixed load inductance noise When the electric power grid, put it aside without noise; when there is no electricity, less than 55dB; YJS-75KW to less than 65dB Dimensions / Weight Dimensions Weight see a list of open the door and into the line method to open the front door of the single, double door open, the bottom of the inlet and outlet.
