Boost and Trim Automatic Voltage Regulation gives higher application availability by correcting low and high voltage conditions without using the battery. Intelligent battery management maximizes battery performance, life, and reliability through intelligent, precision charging. Power conditioning protects connected loads from surges, spikes, lightning, and other power disturbances. Temperature compensated battery charging prolongs battery life by regulating the charge voltage according to battery temperature USB connectivity provides management of the UPS via a USB port Front-access servicing simplifies installation and UPS maintenance while minimizing space requirements Boost and Trim Automatic Voltage Regulation gives higher application availability by correcting low and high voltage conditions without using the battery Nominal Output Voltage is 230 Volt Output Voltage Note is configurable for 220 : 230 or 240 nominal output voltage Output Voltage Distortion less than 5% at full load Output Frequency are 47 - 53 Hz for 50 Hz nominal, 57 - 63 Hz for 60 Hz nominal Topology line Interactive Waveform Type is Sine wave Battery Type: Maintenance-free sealed Lead-Acid battery with suspended electrolyte Typical recharge time 3 hour
