How to use

Install the unit on a TS35 DIN rail inside the control cabinet, ensuring adequate ventilation and clearance from heat sources. Connect the AC mains input to the designated input terminals according to local wiring regulations, and connect the 24V DC output to your load using appropriately sized conductors. Verify correct polarity before powering the system. After initial power-up, check the output voltage and monitor the load to confirm stable operation. Follow standard electrical safety procedures during installation and maintenance.

Usage recommendations

Use appropriate overcurrent protection and wiring sized for the expected load. Avoid locating the power supply near high-temperature sources or enclosed spaces without ventilation. For continuous heavy-load operation, allow sufficient ambient airflow around the device and periodically inspect terminal tightness. Consult equipment manuals for compatibility with connected devices requiring inrush or peak currents.
