# Industrial Specification: Control System Cabinet

## 1. Technical Definition
A protective enclosure housing the electronic control components for the Automated Computer Chassis Assembly System.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-35°C ambient temperature, 20-80% relative humidity (non-condensing), 0-1000 m altitude**. Failure boundary: **Thermal runaway initiates at 85°C internal cabinet temperature, electromagnetic interference susceptibility exceeds 10 V/m at 100 MHz-1 GHz**, Mechanism: **Joule heating in power electronics (P=I²R) combined with inadequate convective cooling (Q=hAΔT) causes component degradation; Faraday cage integrity loss permits EMI-induced signal corruption**.

### 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.
