UL Class 2 refers to a specific classification of power supplies or LED drivers that are designed with safety as a primary concern. These devices are considered safe to use without causing fire or electric shock.
Key Characteristics of UL Class 2 Power Supplies
These power supplies adhere to specific voltage, current, and wattage limitations to ensure safety:
- Voltage Limits: They operate below 60 volts in dry conditions and 30 volts in wet environments.
- Current Limits: The output current is limited to less than 5 amps.
- Wattage Limits: The total output power is limited to under 100 watts.
Why are these limits important?
These restrictions are crucial in preventing electrical fires and shocks, especially in low-voltage systems and LED lighting, making them safer for consumers and installers. The reference information indicates that a UL Class 2 power supply, by adhering to these limits, helps to minimize safety risks associated with electrical power.
Practical Applications
- LED Lighting: Commonly used in LED lighting systems to power individual lights or groups of LEDs safely.
- Low-Voltage Systems: Found in various low-voltage applications where safety is paramount.
- Consumer Electronics: Used in devices requiring lower power, where safety regulations are strictly followed.
Table Summary
| Feature | Limit |
|---|---|
| Voltage (Dry) | < 60 Volts |
| Voltage (Wet) | < 30 Volts |
| Current | < 5 Amps |
