Emergency Power Supply (EPS) is today the important buildings in order to power protection and fire safety and the use of an emergency power supply device. AT series of emergency power supply is widely used in building electrical field and special occasions, emergency power, its principle is: in the normal AC power from the AC power to the unit after each vote is important load when the AC power grid, each switch device will immediately switching to the inverter power supply, when the grid voltage is restored, the emergency power supply will be restored to the power grid, effectively prevent disasters personal injury and property damage. AT series of emergency power supply Features: ● Inverter unit with microprocessor controlled SPWM technology, pure sine wave output, waveform pure ● unique dynamic current-loop control technology to ensure reliable operation of the inverter ● Load adaptable, including capacitors , inductive, mixed loads ● overload and impact resistance, able to withstand full load power ● has input over voltage, output over voltage, over temperature, overload, short circuit protection features such as sound ● Inverter The front panel LCD, LED dual display mode, status at a glance ● high efficiency (non-emergency power supply, almost no power), low noise, no smoke, no fire hidden danger ● Automatic load switching, enabling unattended ● Performance stable, safe and reliable, long life model ATE45KF3 DC input rated voltage 480VDC Quantity 200AH/12V × 40 Battery Type Maintenance-free lead-acid batteries battery battery cabinet number four faces Three-phase AC input frequency 50Hz ± 5% voltage range 380VAC ± 20% rated power 45KW emergency inverter output voltage accuracy of the rated voltage 380VAC 380VAC ± 2% Frequency 50Hz ± 1% Waveform distortion rate ≤ 5% (linear load) Dynamic response 5% (0% to 100% load) crest factor (CF ) 3:1 Inverter efficiency 87% response time of 90 minutes of continuous operation alarm LED and LCD display text alarm alarm switching time <2s charging voltage 560VDC Forced air cooling fan
