LTS DPS-280AB-4 280W Internal Power Supply for 16-Channel PoE NVR

LTS DPS-280AB-4 280W Internal Power Supply for 16-Channel NVRs

The LTS DPS-280AB-4 is a genuine internal replacement power supply engineered for 16-channel IP network video recorders, including select LTS Platinum series NVRs that rely on built-in PoE for camera power delivery. Designed to handle the combined load of a busy 16-port PoE switch, hard drive array, and recorder mainboard, this unit is a reliable option for technicians and installers needing to replace a failed or ageing factory power supply without swapping out the entire recorder.

Key Features

• 280W continuous output rated to comfortably power a 16-channel PoE NVR chassis under full camera load
• Wide AC input range accepting standard Australian 240V mains power
• DC output of 52V at up to 6 Amps, matching the voltage rail most 16-port PoE NVR boards require to energise connected IP cameras
• Internal, drop-in form factor designed to mount inside the NVR chassis rather than as an external brick
• Active PFC (Power Factor Correction) circuitry for improved efficiency and cleaner power draw
• Built with multi-pin connector harnesses compatible with common 16-channel NVR motherboard layouts
• Suitable as a like-for-like replacement part for units originally fitted with this power supply model
• Compact 1U-style internal design that fits standard desktop and rack-mount NVR enclosures

Typical Use Cases

This power supply is most commonly used by security installers and system integrators performing repairs on 16-channel PoE NVRs where the original internal PSU has failed, is underperforming, or is showing signs of wear from continuous 24/7 operation. It is also useful as a stocked spare part for service technicians supporting fleets of LTS Platinum NVR installations, helping minimise system downtime when a recorder loses power to its camera channels or hard drives.

What's in the Box

• 1 x DPS-280AB-4 internal power supply unit
• Connector harness/cabling as fitted to the original unit

Frequently Asked Questions

Is this power supply compatible with any 16-channel NVR?
It is designed for NVR chassis that use the DPS-280AB-4 power module and its associated 52V PoE rail, which covers a range of 16-channel PoE recorders. Always confirm your existing power supply's model number and connector layout before ordering to ensure a correct fit.

Can I install this myself?
Replacing an internal NVR power supply involves opening the recorder chassis and reconnecting internal wiring harnesses, so it should only be carried out by a qualified technician or experienced installer with the unit powered down and unplugged.

What is the output voltage and wattage of this unit?
It supplies 52V DC at up to 6 Amps, delivering a maximum continuous output of 280 Watts to power the NVR's PoE ports, mainboard, and storage drives.
