D-Link 240W Universal AC input / Full range DIN Power Supply

The D-Link DIS-N240-48 240 W power supply unit provides a stable 240 W output in a compact stainless steel enclosure. Designed for use in network and communication equipment, it accepts a wide AC input range of 90–264 V at 47–63 Hz and features an electrical rise time of 100 ms. The unit's compact footprint (63 mm width, 113.5 mm depth, 125.2 mm height) and corrosion-resistant stainless steel housing support reliable operation in rack- or chassis-mounted installations where space and durability matter.

Advantages

This power supply delivers consistent 240 W output with up to 88.5% efficiency, helping to reduce energy losses during operation. The stainless steel construction enhances mechanical strength and resists corrosion, while the broad input voltage and frequency compatibility simplify deployment across different mains environments. Its compact dimensions enable installation in confined spaces without major rearrangements.

Suitable for

• Powering network switches, routers and communication modules
• Replacement or upgrade of existing PSUs in compact racks or enclosures
• Use in small server rooms and telecom closets requiring reliable DC power
• Applications where space-saving and durable housing are required

How to use

Install the power supply into a compatible chassis or secure it within the intended enclosure following the equipment manufacturer's mounting guidelines. Connect the AC mains to the input terminals rated for the specified input range and confirm proper earthing. Route DC output connections to the target device(s) using appropriately rated cables and observe correct polarity. After connections are secured, apply mains power and verify stable output and normal operation with appropriate monitoring or measuring tools.

Recommendations

Ensure ventilation around the unit and avoid mounting near heat sources. Use overcurrent protection on the input and output circuits according to local electrical codes. Perform periodic inspections of connections and the housing for signs of wear or corrosion to maintain reliable performance.
