Description I. Product Overview Product Use: Apply a fire or other emergency situations occur in the building next to the emergency lighting and other lighting (including single into a single metal halide, sodium) to provide centralized power supply emergency power unit. Second, the product features 1, using the latest IGBT inverter technology. 2, centralized power supply mode, no special lighting. 3, when the emergency power supply, sine wave AC output voltage, frequency stabilization, standing no noise, pollution-free. 4, fire linkage, can be a computer monitor, you can control the fire center. 5, isolation transformer output, LCD liquid crystal display. Third, the product advantages of a simple design, easy construction. 2, lower total cost, saving investment. 3, long life, the host life more than 20 years. 4, maintenance-free batteries can be recycled 300 to 500 times. 5, management is simple, automatic instant switching, can be unattended. 6, to maintain illumination stable, reliable, easy to maintain. Four. Technical Specifications 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 supply) sine wave harmonic distortion: ≤3% frequency 50Hz ± 0.5% overload capacity of 120% uptime conversion time ≤0.1 seconds (mains supply into the emergency power supply time; if used with metal halide lamps, switching time may be less than 0.006 seconds) Battery Maintenance-free sealed battery backup time of 60 minutes / 90 minutes / 120 minutes / (when according to design requirements to configure an alternate time) protection Short circuit protection, overcurrent protection, phase can run efficient emergency LCD display: 90 % or more; 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 power When there is electricity, standing no 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.
