• Output voltage: 24V DC
• Power rating: 10W
• Output current: 0.42A
• Integrated relay functionality
• Compact design for DIN rail or panel mounting

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. Connect the AC input lines to the designated terminals, ensuring the voltage is within the specified range. The 24V DC output terminals should be connected to the load, observing correct polarity. The integrated relay should be wired according to the specific requirements of the control circuit to enable the switching function. Ensure adequate ventilation around the unit to prevent overheating during continuous operation.

What to consider before purchase

• Verify that the 10W power output is sufficient for your specific load requirements.
• Ensure the installation environment provides adequate protection from moisture and extreme temperatures.
• Check the physical dimensions to confirm compatibility with your existing control cabinet layout.
• Confirm that the relay contact ratings meet the needs of your switching application.

Usage recommendations

Always ensure that the power supply is disconnected from the mains before making any wiring adjustments. Regularly inspect the terminal connections to ensure they remain tight and free from oxidation to maintain optimal electrical conductivity.
