使用场景 APPLICATIONS

Suitable for industrial equipment, automation systems, test & measurement devices, telecommunications equipment, embedded systems, and other electronic devices requiring stable DC 48V power. Ideal for applications needing remote sense to maintain voltage accuracy at load end, compact space, and wide temperature operation (-20°C~70°C).

注意事项 PRECAUTIONS

1 Ensure input voltage is within the 90-264VAC range

2 Do not exceed the rated output current (2.6A)

3 Use the remote sense function correctly (connect +S and -S to load terminals)

4 Operate within the specified temperature range (-20°C~70°C); derating may be required at higher temperatures

5 Avoid condensing humidity environments

6 Follow safety guidelines and local electrical codes during installation

7 Ensure proper grounding to prevent electric shock
