AC Adapter HP Enterprise M52952-001 280W Slim PFC 3‑pin 7.4 mm

AC Adapter HP Enterprise M52952-001 280W Slim PFC 3‑pin 7.4 mm is a compact external power supply designed for compatible HP Enterprise equipment. It delivers up to 280 watts of output power through a 7.4 mm DC connector and accepts mains input via a three‑pin IEC cable. The adapter integrates power factor correction (PFC) to improve input current quality and reduce reactive power draw, and its slim profile saves space in rack or desk deployments. This unit is intended as a replacement or spare to maintain stable operation of servers, storage arrays and networking devices that require a 7.4 mm barrel connector and 280W power rating.

Advantages

The slim form factor reduces clutter and allows placement in constrained environments while still providing full 280W output. Built‑in active PFC enhances electrical efficiency and helps meet power quality requirements in enterprise installations. The standard three‑pin mains input supports common IEC power cords for straightforward connection and easy replacement. Using a dedicated HP Enterprise adapter ensures connector compatibility and consistent voltage/current delivery for supported devices.

Suitable for

• HP Enterprise servers and tower/workstation devices that require a 7.4 mm DC barrel connector and 280W supply
• Network appliances and storage units with matching power input specifications
• Field replacements and spare inventory for enterprise maintenance

Key specifications

• Output power: 280 W maximum
• DC connector: 7.4 mm barrel type
• Mains input: three‑pin IEC AC connection
• Power correction: active Power Factor Correction (PFC)
• Form factor: slim, external adapter design
• Intended use: external replacement power supply for compatible enterprise equipment

How to use

Confirm that the target device accepts a 7.4 mm DC connector and requires up to 280W before installation. With the mains switch off, connect an appropriate three‑pin IEC power cord to the adapter and plug the adapter’s DC connector into the device’s power inlet until it seats securely. Restore mains power and verify that the connected device powers on and charges or operates normally. For best results, use the adapter in well‑ventilated areas and avoid blocking the adapter’s ventilation surfaces during operation.

Usage recommendations

Use this adapter as a direct replacement only on compatible HP Enterprise equipment that specifies a 7.4 mm DC connector and a 280W external power supply. Avoid using with devices that require different voltages, connector types, or higher/lower wattage ratings. Regularly inspect the cable and connector for damage, and replace the adapter if any signs of wear, overheating or unusual noise occur.
