Direct Replacement for HIKVISION 7816N Recorders

This 280 watt server power supply is built as a direct replacement for the HIKVISION POE Hard Disk Recorder model 7816N. It matches the original KSA-300S2 and DPS-280AB-4A/4B/6C part numbers to restore reliable operation in surveillance systems that have lost their original unit.

OEM Build With Universal Input Range

The unit accepts a wide 100 to 240 volt input at 50 to 60 hertz, allowing it to operate on standard mains power worldwide without manual switching. Its OEM construction fits the recorder chassis exactly, so the existing mounting points and power connectors align without adapters or modifications.

Restores Full POE And Recording Function

Install this supply when the original unit fails or shows unstable voltage under load, which can cause drive errors or camera dropouts. The 280 watt rating supports the recorder's PoE ports and internal hard drives simultaneously, making the upgrade worthwhile whenever the system powers on intermittently or shuts down during recording.
