All UPSs in this series can be turned on directly from battery (cold start function) and internal batteries can be charged in standby mode. This model comes with a USB port with HID support and can be monitored and controlled using the PowerWalker ViewPower software (available for download from our website) or directly using O/S’ native drivers thanks to HID. To offer the best price-performance and to reduce environmental impact we provide the UPS without Software CD and USB cable.
