CSA C22.2 No. 223
CSA C22.2 No. 223 applies to Class 2 power supplies and low output energy sources. It is the Canadian equivalent for products covered in the U.S. by UL 1310. This standard addresses power units with limited output capacity that are considered lower risk for electric shock and fire.
Key Test Areas:
1. Output limiting verification (energy hazard protection)
2.Dielectric strength and insulation integrity
3. Temperature rise under normal and abnormal loading
4. Strain relief and mechanical construction
5. Overload and short-circuit protection
Project Details
This standard covers Class 2 power units with outputs not exceeding 30 Vrms or 60 Vdc, 5 A, and 100 VA. It applies to low-energy output power supplies including certain LED drivers and battery charging devices.
