AT Series EPS emergency power supply, reflecting the world's most advanced power electronics technology, is a full-featured, high performance uninterruptible power supply with high efficiency, high reliability, high intelligence advantages. We are very pleased to offer this product to you, I hope for you in the coming years to provide convenient, reliable service to ensure your equipment safe operation. AT Series EPS emergency power supply technical features: ● Emergency unit SPWM technology with microprocessor control, pure sine wave output, waveform pure ● unique dynamic current-loop control technology to ensure reliable operation of the emergency control ● capacitive load adaptability, including inductive mixed load ● overload capacity and impact resistance. ● have input, undervoltage, output over voltage, over temperature, overload perfect protection function ● emergency power supply front panel LCD, LED double display status at a glance ● high efficiency (non-emergency power supply, the basic power) low noise, no smoke, no fire load hidden ● Automatic switching unmanned ● stable performance, safety and reliability, long service life, mainly number of technical parameters Model AT-6KW DC input rated voltage 192VDC battery 12V 16 battery type maintenance-free lead acid battery relative to the number of single-phase ac input frequency 50Hz ± 5% voltage range 220V ± 20% the emergency inverter output power rating 6KW rated voltage the 220VAC voltage accuracy 220VAC ± 3% Frequency 50Hz ± 1% waveform distortion rate ≤ 5% (linear load) Dynamic response 5% (0% to 100% load) crest factor (CF) 3:1 inverter efficiency ≥ 85% alarm LED indicator alarm and LCD the text alarm switch time ≤ 1S charging voltage 218VDC noise (state of emergency) 55db (1 meter in front) cooling fan forced air-cooled emergency power protection features AT Series has perfect protection function, once appeared in the following table listed failure, emergency power supply will enter a state of emergency on or off the output, in order to ensure that the load from damage, while power inverter itself are protected. The protected functional status protective action to restore AC input under-voltage AC input voltage is below the set point emergency power will automatically be converted to emergency power troubleshooting, power inverter will automatically resume normal working condition AC input voltage AC input voltage is higher than the setpoint emergency power supply will automatically be converted to emergency power DC input under-voltage DC input voltage is below the set point output under the state of emergency will be closed emergency output over the carrier load power exceeds the rating of the emergency power supply will turn off the output troubleshooting, to be re- start to return to normal working condition of output short circuit after a slip short emergency power to close a particular branch output troubleshooting, replace the fuse of a slip Note: emergency power supply undervoltage, overvoltage protection after, it must return to the set recovery points or more, in order to start again. Set hysteresis to prevent avoid shock protection near. When the first power of the power inverter, if the input voltage protection point and recovery point just in between, the machine is protected.
