Product Overview

Defon Electronics manufactures high-quality Class 2 transformers designed to meet UL Class 2 power-limited requirements for safe low-voltage applications.

Class 2 transformers are engineered to ensure that output power is inherently limited, reducing the risk of electrical shock and fire hazards. These transformers are widely used in low voltage lighting systems, control circuits, security devices, and building automation systems.

Our Class 2 transformers are available in multiple power ratings and can be fully customized according to voltage, enclosure type, and application requirements.
