Note: The Uniview PWR-300A-IN is a 300W AC Redundant Power Supply Module designed for NVR systems with high storage requirements. It accepts 90~264V AC input and provides +12VDC/25A output with a maximum output power of 312W. It supports 1+1 redundant backup, hot plug and load sharing for improved system reliability.
Important: The PWR-300A-IN is a Redundant Power Supply Module, not a standalone NVR. It supports 1+1 redundant backup, hot plug and load sharing and is designed for compatible Uniview NVR systems such as the NVR516 series and other systems using the Unicorn platform. It provides +12VDC / 25A output with a maximum power of 312W and includes short-circuit, overload, overvoltage and over-temperature protection.
