The CHA Semi-Potted Series industrial power supply is designed for applications requiring enhanced environmental protection and improved durability. Featuring a semi-potted internal structure, this series offers increased resistance to dust, moisture, vibration, and harsh operating conditions while maintaining efficient heat dissipation.

Compared to fully enclosed or fully potted designs, the semi-potted structure provides a balanced solution between protection and thermal performance. This makes it ideal for industrial environments where reliability is critical but heat management is equally important.

With stable output performance and high efficiency, the CHA series is suitable for automation systems, industrial equipment, and outdoor or semi-outdoor installations. Built-in protection features ensure safe and continuous operation under demanding conditions.
