NDR-120-12 120W 12VDC 10Amp DIN Rail Power Supply Dual Output SMPS (120W 12V 10A)

The NDR-120-12 is a robust and highly efficient 120-watt enclosed switching power supply designed to deliver reliable and stable DC power in a wide range of demanding industrial, telecommunications, and automation applications. Engineered with advanced switch-mode technology, this power supply converts a universal AC input voltage ranging from 85 to 264 volts AC, at a frequency of 47 to 63 Hz, into a precisely regulated 12-volt DC output capable of supplying up to 10 amps of continuous current, ensuring consistent performance even in environments with fluctuating or unstable mains power. Its wide input voltage range makes it suitable for global deployment, eliminating the need for different models for various regional grid standards and providing inherent resilience against voltage sags, surges, and electrical noise commonly encountered in industrial settings.

The unit boasts a high conversion efficiency of up to 89%, which minimizes energy loss, reduces heat generation, and lowers operational costs, while its low no-load power consumption makes it an energy-efficient solution for systems that require always-on power availability. The NDR-120-12 is built with a comprehensive suite of protection features to safeguard both the power supply and the connected load, including overload protection (OLP) which limits output current during excessive demand, over-voltage protection (OVP) that shuts down the output to prevent damage to sensitive electronics in case of an internal fault, and short-circuit protection (SCP) that allows the unit to operate continuously into a shorted output by automatically entering a hiccup-mode recovery state, resuming normal operation once the fault is cleared.

Additionally, it includes thermal protection that derates output power at elevated temperatures to prevent overheating, ensuring long-term reliability and durability. Housed in a compact yet rugged metal enclosure, the power supply provides effective heat dissipation and electromagnetic shielding, contributing to its ability to operate reliably within a wide temperature range from -30 degrees Celsius to +70 degrees Celsius, with appropriate derating above 50 degrees Celsius to maintain performance and longevity.
