Uninterruptible Power Supply Centurion RT PSCERT1000 1000VA Pure Sine Wave DA0901

SKU: DA0901


Perfect for servers, motor driven and sensitive devices requiring a perfect sine wave to operate correctly. LCD provides real time battery management, showing battery and load level. All outlets are battery backup and surge protected. Includes software which communicates via USB or RS-232. All provide phone line surge protection (RJ45). Typical backup: 5 min full load, 14 min half load.

Line Interactive UPS: Regulates the power as it falls and surges. They offer protection against surges, sags, brownouts, spikes, radio and electrical interferences. If the spike or sag is severe (over 24V above or below nominal 240V output), the UPS will transfer the load to the batteries. The reason why it is called a Line Interactive UPS is because it only interacts when there are fluctuations in the power line.
