B&K Precision 8540 DC Electronic Load

Overview

The B&K Precision 8540 is a compact, economically priced DC electronic load designed for both benchtop and production floor testing. Despite its small footprint and lightweight design, the 8540 reliably tests 5-volt power supplies up to 30 amperes continuously.

The instrument offers performance comparable to full-size bench DC electronic loads while occupying half the space at half the cost, making it an excellent choice for a variety of DC power source testing applications.

Key Features

• Operating voltage range 0–60 VDC with current range 1 mA–30 A (150 W maximum)
• Constant current (CC), constant resistance (CR), and constant voltage (CV) operation modes
• Two current ranges: 3 A (1 mA resolution) and 30 A (10 mA resolution)
• Over-current and over-voltage protection
• Short mode to simulate short circuit conditions
• Save up to 400 instrument settings for convenient recall
• Bright, easy-to-read display with real-time voltage, current, resistance, and power measurements
• Very compact and lightweight for benchtop or portable use

Applications

• Power supply testing and characterization
• Battery discharge profiling
