# Industrial Specification: Power Supply System

## 1. Technical Definition
A component that provides electrical power to the Industrial System.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **85-264 VAC, 47-63 Hz, 0-40°C ambient temperature**. Failure boundary: **Input voltage below 85 VAC causes undervoltage lockout; above 264 VAC causes overvoltage protection trip; ambient temperature above 40°C reduces maximum output current by 2.5% per °C until thermal shutdown at 85°C internal temperature**, Mechanism: **Insulation breakdown at voltages exceeding 3000 V/m dielectric strength; semiconductor junction thermal runaway when junction temperature exceeds 150°C; electrolytic capacitor electrolyte evaporation above 105°C**.

### 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.
