A Class II driver, particularly in the context of LEDs and lighting, is a power supply designed with specific safety characteristics. According to UL1310, their output is considered safe for contact, requiring no major safety protection at the LED or luminaire level because they pose no significant risks of fire or electric shock.
Key Characteristics of Class II Drivers
-
Safety Focus: The primary feature of a Class II driver is safety. They are designed to limit both voltage and current to safe levels.
-
Compliance: Class II drivers comply with UL1310 standards, ensuring they meet strict safety requirements.
-
Safe Output: The output is considered safe to touch. This eliminates the need for additional safety measures at the LED or fixture.
-
Risk Mitigation: Class II drivers significantly reduce the risk of fire and electric shock.
Benefits of Using Class II Drivers
- Simplified Design: Since additional safety mechanisms aren't needed at the LED or luminaire, product design becomes simpler.
- Cost Savings: Eliminating extra safety components translates to lower manufacturing costs.
- Enhanced Safety: Users are protected from potential electrical hazards.
- Versatile Applications: Class II drivers are suitable for various applications where safety is paramount.
Example Uses
Class II drivers are commonly used in:
- LED lighting systems
- Low-voltage landscape lighting
- Signage
- Under-cabinet lighting
