Teollinen DIN-kiskovirtalähde QOLTEC 50901 — 480W, 24V DC, 20A

DIN rail power supply QOLTEC 50901 delivers 480W of continuous output at 24V DC and up to 20A, designed for industrial and automation applications. The unit is intended for mounting on a standard DIN rail and provides steady, regulated power to control panels, PLCs, sensors and actuators. Built to meet the needs of factory equipment, machine control cabinets and building automation, this QOLTEC power supply focuses on stable 24V distribution with protection and thermal management required in professional installations.

Advantages

The power supply offers a high power density with 480W output in a compact DIN-rail housing, enabling space-efficient installation in control cabinets. Output regulation at 24V DC and a maximum current of 20A ensure reliable operation of connected devices. The unit includes standard protection features and thermal design suitable for continuous industrial operation, reducing downtime and simplifying system wiring by centralising 24V power distribution.

Suitable for

• Industrial control cabinets and machine automation systems
• Programmable logic controllers (PLCs) and control panels
• Sensors, actuators and field devices requiring 24V DC
• Building automation and HVAC control systems

Key specifications

• Output power: 480W continuous
• Output voltage: 24V DC (regulated)
• Maximum output current: 20A
• Mounting: standard DIN rail (35 mm)
• Intended use: industrial and automation installations
• Protection and thermal design suitable for continuous operation

How to use

Install the unit on a standard 35 mm DIN rail inside the control cabinet and connect the AC input according to local wiring standards and applicable safety regulations. Connect the 24V DC positive and negative outputs to the load circuits, observing correct polarity and cumulative current limits so as not to exceed the 20A rating. Ensure adequate ventilation around the device and route wiring to minimise electromagnetic interference. Regularly inspect terminal connections and ambient conditions to maintain reliable operation.

Recommendations

Place the power supply in an environment that matches the manufacturer's specified ambient temperature and ventilation requirements, separate from high-heat sources. Use appropriate fuses or circuit breakers on input and output circuits, size wiring for the 20A load, and avoid exceeding combined output current. For long cable runs, consider voltage drop and use thicker conductors or local distribution points to maintain stable 24V at end devices.
