How to use

Mount the power supply inside a suitable control cabinet or equipment rack with adequate ventilation and secure fixing. Connect the AC input to the 90–305 V mains following local wiring regulations and connect the 24 V DC output to the load, observing correct polarity. Use the built-in potentiometer to fine-tune the output voltage if required. Ensure the total connected load does not exceed 240 W or 10 A continuous.

Recommendations

Install the unit where ambient temperature and airflow meet the manufacturer's specifications, provide proper fusing on the input side, and avoid exposure to excessive shock or sustained temperatures above rated limits. For critical applications, verify startup and loading behavior under expected operating conditions.
