Product Overview

Defon Electronics manufactures water-proof toroidal transformers designed for reliable operation in outdoor, humid, and harsh environmental conditions.

These transformers are built with advanced sealing techniques such as epoxy potting or protective encapsulation to prevent moisture ingress, dust contamination, and corrosion damage.

Compared with standard transformers, our water-proof toroidal design provides higher safety, improved durability, and stable performance even in demanding environments.

They are widely used in outdoor lighting systems, marine equipment, security systems, industrial outdoor installations, and any application requiring moisture-resistant and long-life power supply solutions.

We offer full OEM/ODM customization including voltage, power rating, IP protection level, and mechanical structure.
