The Power Walker VI (Voltage Independent / Independent Voltage) series provides a stable and consistent power supply. Thanks to the integrated AVR function (see description product group AVR) protected all connected devices already in network operation. The AVR function allows power fluctuations within certain limits, compensate without having to rely on the UPS batteries. Thus a longer battery life is achieved. In the case of larger power fluctuations and in the case of a total failure of the power system, the UPS switches to battery mode. Then the connected devices are powered by the generated by the UPS from the AC and batteries optimally protected. All devices in the Power Walker VI series are equipped with a USB port and to a large extent with serial (RS-232) interface. This allows you to connect to almost any PC system to monitor and control both the affiliated and other UPS in your own network.
