Delta DPS-200PB-185 B 190W Power Supply — Replacement PSU for NVRs, Video Recorders and PoE Devices

Restore a dead NVR or video recorder with the original Delta 190W supply.

The Delta DPS-200PB-185 B is a 190W internal power supply used in network video recorders, DVRs and PoE-equipped devices. It accepts 100–240V AC input (3.5A, 47–63Hz) and connects through 4-pin and 2-pin output connectors. It suits CCTV installers and security integrators repairing recorders.

Why NVR Power Supplies Fail and How to Fix It Fast

NVRs run around the clock, power several hard drives and often feed PoE cameras. That continuous load, combined with dust and heat in equipment cabinets, makes the power supply one of the most common failure points.

When the supply fails, recording stops and cameras without separate power go dark. Replacing it with the DPS-200PB-185 B, the same Delta unit used in the recorder, restores recording without swapping the whole NVR or reconfiguring cameras.

Sized for Drives and PoE

The 190W rating covers recorder electronics, multiple surveillance hard drives and the PoE budget of recorders with built-in camera ports. That avoids brownouts during drive spin-up.

Direct Harness Connection

The 4-pin and 2-pin output connectors match the recorder’s internal wiring, and the mounting holes line up with the original unit, so installation does not require modifications.

Setup Instructions

How to Replace the Delta DPS-200PB-185 B

1. Shut down the recorder, unplug the AC cord and press the power button for a few seconds to drain residual power.
2. Open the side panel, photograph the cable routing, then disconnect the power cables from the motherboard, drives and any graphics card.
3. Remove the mounting screws or release latch, take out the old unit and install the replacement in the same position.
4. Reconnect every cable, close the case, plug in the AC cord and power on to confirm the system boots and the fan spins.
