Equipment - Power Supplies (Test, Bench)

1. Overview

Bench power supplies are adjustable DC or AC power sources designed for testing, troubleshooting, and development in electronic engineering. They provide stable, precise, and controllable electrical power to devices under test (DUTs) in laboratory, production, and field service environments. Their importance lies in ensuring product reliability, validating circuit performance, and supporting R&D workflows across industries.

2. Major Types and Functional Classification

Type	Functional Features	Application Examples
Linear Power Supplies	Low noise, high stability, fast transient response	Laboratory testing of analog circuits
Switching Power Supplies	High efficiency (>80%), wide input range, compact size	Automated production line testing
Programmable Power Supplies	Computer-controlled output, waveform generation, data logging	Automotive electronics validation
Multi-channel Power Supplies	Independent voltage/current control for multiple outputs	Testing IoT devices with multiple rails

3. Structure and Components

Typical bench power supplies include:

Metallic enclosure with ventilation slots
AC/DC power module (linear/regenerative topology)
Control panel with digital/analog interfaces
Output terminals (banana jacks, binding posts)
Active cooling system (fan/heat sink)
Communication ports (USB/LAN/GPIB)

4. Key Technical Specifications

Parameter	Description	Importance
Output Voltage Range	0-200V (single/multi-range options)	Determines compatibility with DUT requirements
Current Resolution	1mA-10 A precision	Impacts test accuracy for low-power devices
Load Regulation	<0.01% change under varying load	Ensures stable output during dynamic testing
Ripple & Noise	<3mV_pp @ 20MHz bandwidth	Critical for sensitive analog circuit testing
Transient Response Time	10-100 s recovery time	Measures stability during sudden load changes

5. Application Fields

Electronics manufacturing (IC testing, PCB validation)
Telecom equipment (5G base station power simulation)
Automotive R&D (ECU power cycling tests)
Aerospace (avionics power quality analysis)
Educational labs (student project prototyping)

6. Leading Manufacturers and Products

Manufacturer	Representative Product	Key Features
Keysight Technologies	N6700 Modular Power System	Hot-swappable modules, 16-bit resolution
Teledyne LeCroy	TS-8080	800W regenerative AC/DC source
Siglent Technologies	SPD1168X	16-bit touchscreen control, list mode
Chroma Systems	62000P Series	Grid simulation, energy recovery

7. Selection Recommendations

Key considerations:

Match output specs to DUT's maximum power requirements
Choose appropriate control interface (analog/digital)
Assess thermal management needs for continuous operation
Prioritize calibration features for traceable measurements

Example: For battery simulation applications, select a bidirectional power supply with dynamic profiling capabilities.

8. Industry Trends

Current development trends include:

Integration of AI-based predictive maintenance
Higher power density (3-5W/cm ) through GaN technology
Adoption of PMBus for smart power system management
Expansion of 800V DC test capabilities for EV applications
Cloud-connected power supplies for remote monitoring
