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.
Usage 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.
