ALSEYE

ALSEYE 48V 3.75A 180W 4-Pin Power Adapter

SKU CH-6KD7-DQ0EQ

48 V 3.75 A 180 W four-pin AC/DC adapter for Swann 16-channel 4K NVR security recorders, with 110–240 V input and over-voltage, over-current and short-circuit protection

  • Worldwide 110-240 VAC input works across regions
  • 48 V 3.75 A output delivers 180 W to the recorder
  • OVP OCP SCP protections guard against voltage current and short-circuit faults
  • 4-pin connector fits Swann NVR16-8580 16-channel 4K NVR systems
  • Not for e-bike or lithium-battery charging applications

48 V 180 W 4-Pin Power Adapter

This ALSEYE adapter delivers 48 V at 3.75 A for 180 W total output through a 4-pin connector. It accepts 110-240 VAC at 50 or 60 Hz and includes over-voltage, over-current and short-circuit protection. The unit is designed to power compatible Swann 16-channel 4k network video recorders. It is supplied new and tested for working condition.

Replaces original NVR power supply

The adapter matches the CS-4803750 and FJ-SW2028A48003750 part numbers used with Swann NVR16-8580 and NVR168580 recorders. Swapping in this unit restores power when the factory supply fails or is lost. The jump is worth it when the recorder shows no power lights or cannot boot with the original brick.

4-pin 48 V DC interface limits

The 4-pin connector and fixed 48 V 3.75 A output restrict use to devices that specify exactly this voltage, current and pinout. The adapter cannot charge lithium-ion batteries, power e-bikes, balance cars or any device requiring a different voltage or connector. It is not a general-purpose 48 V source for other equipment.

Questions about this item

What type of power connector does the 48 V 180 W adapter use for the Swann NVR?

It uses a 4-Pin DC connector that matches the Swann NVR16-8580 and compatible 16-channel 4k recorders.

What AC input range does the adapter accept, and what is the common wiring mistake?

It accepts 110-240 VAC at 50/60 Hz; the common mistake is plugging the DC output into a device that requires a different voltage or pin-out.

Which internal protection circuits may eventually trip and require a power-cycle to reset?

Over-voltage, over-current and short-circuit protections can trip under fault conditions; removing the fault and cycling mains power restores operation.
