Power Supply DIN Rail Triton Mean Well NDR-120-48 48V 120W 2.5A

The Triton Mean Well NDR-120-48 is a DIN-rail mounted switching power supply providing a 48 V DC output with up to 2.5 A current and 120 W continuous power. Designed for industrial and automation environments, the unit fits standard TS35/7.5 and TS35/15 rails in control cabinets and distribution panels. It supplies stable voltage suitable for PLCs, sensors, communication modules and other control equipment where a compact, reliable DC source is required.

Advantages

The compact metal housing allows mounting on standard DIN rails while offering mechanical stability and efficient heat dissipation. Built-in protections against short circuits and overloads help preserve connected equipment and reduce downtime. The switching topology delivers regulated output voltage with low ripple and good efficiency, which contributes to lower heat generation and steady operation under varying loads.

Suitable for

• Industrial control cabinets and PLC power supply
• Sensors and actuator power in automated production lines
• Communication equipment and network devices in industrial environments
• Embedded systems and instrumentation requiring 48 V DC

Key specifications

• Output voltage: 48 V DC
• Maximum output current: 2.5 A
• Continuous output power: 120 W
• Mounting: DIN-rail (TS35/7.5 or TS35/15)
• Protection: short-circuit and overload protection
• Cooling: convection cooling via ventilated housing
• Form factor: compact metal enclosure for industrial cabinets

How to use

Mount the power supply on a compatible TS35 DIN rail inside a suitably ventilated enclosure. Connect the AC input to a properly fused mains source following local electrical codes, and attach the DC output cables to the intended loads, observing correct polarity. Verify that the combined load does not exceed the 120 W/2.5 A rating and that wiring and terminal tightening are secure. Allow adequate spacing for airflow and avoid placing the unit near heat sources or in locations with excessive vibration.

Usage recommendations

For reliable long-term operation, install the unit in a dry, dust-reduced environment with ambient temperature within the manufacturer's specified range. Use appropriately rated fuses or circuit breakers on the AC supply, and consider adding surge protection if the installation is exposed to electrical transients. Periodically inspect terminals for tightness and check for signs of overheating or corrosion.
