What Does High PF Mean in a 24V 400W LED Driver?
PF, or Power Factor, measures how efficiently electrical power is converted into usable output power. A high PF LED driver typically has a power factor of 0.95 or above, which means less reactive power and reduced load on the electrical grid.
- Improves overall energy efficiency
- Reduces electricity costs for commercial and industrial users
- Complies with international energy regulations
- Minimizes harmonic distortion
In large-scale installations such as factories or outdoor lighting systems, using a High PF 24V 400W Constant Voltage LED Driver can significantly enhance system performance and sustainability.
How Does a Constant Voltage LED Driver Work?
A constant voltage LED driver supplies a fixed output voltage, in this case 24V, regardless of load variations within its rated power range. This makes it ideal for LED strips, modules, and panels designed for constant voltage operation.
Key working characteristics include:
- Stable 24V DC output
- Compatibility with parallel LED connections
- Built-in protection functions such as over-voltage, over-current, and short-circuit protection
Shenzhen Fushuo Photoelectric Technology Co., Ltd. designs constant voltage LED drivers with advanced circuitry to ensure consistent brightness and extended LED lifespan.
Why Choose a 24V 400W LED Driver for High-Power Applications?
A 400W LED driver provides sufficient power for large or high-density lighting systems. When combined with a 24V output, it offers a balance between safety, efficiency, and flexibility.
| Feature | 24V 400W LED Driver | Lower Power Driver |
|---|---|---|
| Total Output Power | Up to 400W | Typically below 200W |
| Application Scale | Large commercial & industrial | Small residential |
| Efficiency | High with PF ≥ 0.95 | Moderate |
| System Expansion | Supports more LED loads | Limited |
Which Applications Use High PF 24V 400W Constant Voltage LED Drivers?
