How to use

Install the open-frame power supply in a ventilated enclosure that allows airflow to and from the side fan. Connect the AC input to a properly fused mains source within 80–264 V AC, observing correct polarity and protective earth connections. Route the 12 V DC output to the load using appropriately rated cables and connectors. Ensure installation follows applicable medical and local electrical standards and verify output voltage under load before connecting sensitive equipment.

Recommendations

Maintain clear airflow around the side fan, avoid obstructing the cover, and operate the unit within specified ambient temperature and ventilation limits. For medical applications, perform installation and safety checks according to EN60601 and local regulations; ensure regular maintenance of the cooling fan to preserve reliable operation.
