Detailed Specifications
Overview
The MEAN WELL NDR-240-24 is a 240W single-output industrial DIN rail power supply designed to provide regulated 24V DC power for industrial control and automation equipment. It accepts a wide AC input range and uses a compact metal housing for DIN rail installation.
Technical Information
The NDR-240-24 provides a rated 24V DC output at 10A, with an adjustable output range of 24–28V. It accepts 90–264VAC or 127–370VDC input and incorporates active power factor correction. Typical efficiency is 88.5%.
Installation and Compatibility
The power supply is designed for installation on TS-35/7.5 or TS-35/15 DIN rails. It is intended for industrial control systems, factory automation, semiconductor fabrication equipment, and electro-mechanical applications. The unit requires appropriate cabinet clearances for continuous full-power operation.
Protection
The NDR-240-24 provides short-circuit, overload, over-voltage, and over-temperature protection. Overload protection uses constant-current limiting and automatically recovers after the fault condition is removed.
Key Features
- 240W rated output power
- 24V DC output at up to 10A
- Universal 90–264VAC input range
- DIN rail mounting for TS-35/7.5 and TS-35/15 rails
- Active PFC with multiple protection functions
Applications
The NDR-240-24 is suited to industrial control panels, factory automation equipment, semiconductor fabrication equipment, and electro-mechanical systems requiring a 24V DC DIN rail power source.
DC Supplies Product Note
For cabinet deployment, verify available DIN rail space and provide the manufacturer's recommended ventilation clearances. MEAN WELL recommends 40mm clearance above, 20mm below, and 5mm on each side for permanent full-power loading.
