Power supply INTER-TECH SDN 24-40 24V 40W DIN rail-mounted

DIN rail-mounted power supply INTER-TECH SDN 24-40 provides a regulated 24 V DC output with a 40 W power rating for industrial and automation environments. The unit is intended to supply stable low-voltage power to programmable logic controllers, sensors, relays and other small devices within control cabinets and electrical panels. Its compact housing and standard DIN-rail form factor facilitate space-efficient installation and integration with other automation equipment.

Advantages

The INTER-TECH SDN 24-40 delivers a constant 24 V DC output with thermal and overload protection features to maintain reliable operation under varying load conditions. The compact design reduces cabinet space requirements while the DIN rail mounting enables quick and secure attachment. The power supply is built to industry expectations for industrial use, providing steady voltage suitable for sensitive control electronics and peripheral devices.

Suitable for

• Powering PLC modules and control electronics in automation panels
• Supplying sensors and field devices that require 24 V DC
• Feeding relays, contactors and small actuators
• Use in industrial control cabinets and distribution boards

Key specifications

• Output voltage: 24 V DC
• Maximum output power: 40 W
• Mounting: Standard DIN rail (TS35) compatible
• Form factor: Compact enclosure suitable for control cabinets
• Protection features: Built-in overload and thermal protection (as typical for industrial supplies)

How to use

Mount the power supply on a standard DIN rail inside the control cabinet and secure it according to panel safety guidelines. Connect the AC input conductors to the designated terminals following local electrical codes and ensure correct grounding. Connect the 24 V DC output terminals to the load, observing polarity and current limits. Verify connections before energizing the unit and monitor for correct output voltage under load during initial commissioning.

Recommendations

Install the unit in a ventilated area inside the cabinet to allow heat dissipation, avoid mounting near high-heat components, and use appropriate fusing or circuit protection on the input and output circuits. For reliable long-term operation, size the supply to provide adequate headroom above the continuous load and follow local wiring regulations during installation.
