# Industrial Specification: Redundant Power Supply

## 1. Technical Definition
A backup power system that ensures continuous operation of the Multi-Protocol Network Protocol Analyzer by providing alternative power sources when the primary supply fails.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **85-264 VAC, 47-63 Hz, 100-240 VDC**. Failure boundary: **Input voltage below 85 VAC or above 264 VAC for &gt;100 ms, frequency deviation beyond ±3 Hz from nominal, or DC input outside 100-240 VDC**, Mechanism: **Semiconductor junction breakdown in power MOSFETs at &gt;600 V drain-source voltage, transformer core saturation below 47 Hz, electrolytic capacitor electrolyte evaporation at &gt;105°C ambient temperature**.

### 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.
