The PowerWalker VI (Voltage Independent) series provides a stable and consistent power supply. Thanks to the integrated AVR function, all connected devices are protected even during normal operation. The AVR function allows for compensation of voltage fluctuations within certain limits without having to rely on the UPS batteries, thereby extending their lifespan. In the event of larger voltage fluctuations or a complete power outage, the UPS switches to battery mode. During this time, the connected devices are powered by the AC current generated from the batteries and are optimally protected. All devices in the PowerWalker VI series are equipped with a USB port and, for the most part, also feature a serial (RS-232) interface. This enables connection to almost any PC system for monitoring and controlling both the connected UPS and other UPS units within the network. Monitoring software is included for this purpose. Optionally available plug-in cards (SNMP, AS/400) expand these connectivity options.
