MeanWell NDR-240-24 SMPS Power Supply

About MeanWell NDR-240-24 SMPS Power Supply

The Mean Well NDR 240 24 is a high performance industrial DIN rail mounted switching power supply engineered for reliability, durability, and efficient power delivery in a wide range of automation, control, and industrial applications. This rugged power supply is part of the NDR 240 series from Mean Well a well established global brand renowned for manufacturing world class power conversion solutions that meet stringent quality and performance standards.

At its core, the NDR 240 24 delivers a 24V DC output at up to 10A, providing a total of 240W of continuous output power ideal for powering PLCs, sensors, actuators, control panels, relays, indicator lights, and other DC powered industrial devices. Its compact footprint and DIN rail form factor make installation quick and space efficient in control cabinets or electrical enclosures.

Compact and Robust Design

Designed to fit standard TS 35/7.5 or TS 35/15 DIN mounting rails, the NDR 240 24 features a slim profile (approximately 63mm wide) that maximises usable panel space. Its metal housing not only enhances mechanical strength but also improves heat dissipation a critical factor for stable operation in industrial environments. The compact design aids in efficient thermal management, which ensures continuous operation without overheating.

Wide Input Voltage and Universal Compatibility

The power supply accepts a wide input voltage range from 90VAC to 264VAC, which makes it suitable for use in virtually all standard industrial and commercial electrical systems globally. It also supports DC input from approximately 127V to 370V DC, expanding its flexibility for installations where DC power sources are present. This universal input capability simplifies procurement and deployment across multi region facilities.

Reliable and Efficient Performance

Mean Well has engineered the NDR 240 24 with thoughtful electrical performance features. It includes active power factor correction (PFC), which improves input current waveform and ensures efficient energy usage under varying load conditions. The design enables a high efficiency rating typically around 88.5% or higher meaning less wasted energy and reduced heat generation compared to non PFC power supplies. This helps lower operational costs and enhances long term reliability.

IndustrialïGrade Protection Mechanisms

Safety and protection are paramount in any industrial power module. The NDR 240 24 incorporates comprehensive protection features:

• Short Circuit Protection (SCP): Automatically limits current in the event of a short, preventing damage to both the power supply and connected loads.
• Overload Protection (OLP): When load exceeds rated power, the unit enters a constant current mode to prevent overcurrent damage and returns to normal operation once the condition is resolved.
• Overvoltage Protection (OVP): Prevents output voltage from rising beyond safe thresholds, safeguarding sensitive control circuits.
• Over Temperature Protection (OTP): If internal temperatures exceed safe limits, the supply shuts down and recovers once temperatures normalise.

These built in protections ensure that the NDR 240 24 maintains stable output and resilience against adverse operational conditions a necessity for systems such as factory automation, process control, or monitoring equipment where downtime is costly.

Convection Cooling for Silent Operation

Unlike fan cooled supplies that introduce mechanical noise and moving parts prone to wear, the NDR 240 24 uses free air convection cooling. The absence of an active fan contributes to silent operation and reduces maintenance needs, making this unit ideal for cabinets where noise or airflow restrictions might be a concern..
