# Industrial Specification: Driver/power supply

## 1. Technical Definition
Electronic component that regulates and supplies power to LED lighting systems

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **85-305 VAC, 47-63 Hz, 0.5-5.0 A**. Failure boundary: **Input voltage &lt;85 VAC or &gt;305 VAC for &gt;100 ms, junction temperature &gt;125°C, output current &gt;5.5 A**, Mechanism: **Thermal runaway due to semiconductor junction temperature exceeding 125°C, causing breakdown of silicon lattice structure and permanent damage to MOSFET/IGBT components**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the difference between constant current and constant voltage LED drivers?
**A**: Constant current drivers maintain a fixed current output (ideal for series-connected LEDs), while constant voltage drivers provide stable voltage (best for parallel LED configurations). Our drivers support both modes with automatic detection.

### Q: How do I select the right wattage for my LED lighting system?
**A**: Calculate total LED wattage plus 20% headroom. For example, for 80W of LEDs, choose a 100W driver. Our drivers operate at 90%+ efficiency with overload and short-circuit protection.

### Q: Are these drivers compatible with dimming systems?
**A**: Yes, our drivers support 0-10V, PWM, and TRIAC dimming protocols. The PCB design includes filtering capacitors and control ICs for smooth dimming without flicker across 100-277V input ranges.
