Description
Precision and Control with LD400 Series DC Electronic Load
The Aim-TTi LD400 Series DC Electronic Load is designed to deliver precise and efficient testing for DC power sources including power supplies, converters, and batteries. With a power dissipation capacity of 400W continuous and 600W short-term, it provides reliable and consistent performance for both bench and automated test setups.
Wide Range and Multi-Mode Operation
Offering a voltage range of 0–80V and a current range of 0–80A, the LD400 Series covers a wide variety of test applications. It supports five operating modes—constant current (CC), constant voltage (CV), constant resistance (CR), constant conductance (CG), and constant power (CP)—giving engineers complete flexibility for simulation and analysis.
Advanced Transient Testing and Accuracy
The LD400 integrates a built-in transient generator with adjustable slew rates for dynamic load testing, making it ideal for evaluating the response and stability of power devices. With high accuracy and fine control, users can achieve stable measurements even at low operating voltages (<1V at 40A).
Battery Testing and Monitoring
The variable drop-out voltage function enables realistic battery discharge and performance evaluations. A current monitor output is also available for waveform observation using an oscilloscope, enhancing the insight into device behavior under test.
Intuitive Display and Easy Operation
A high-resolution backlit graphical LCD combined with soft-key navigation simplifies setup and operation. The design prioritizes user convenience while maintaining professional-grade control precision.
Connectivity and Remote Control
The LD400P version includes USB, RS232, and LXI-compliant LAN interfaces for complete remote operation and automation. An optional GPIB interface is also available. Front and rear terminal configurations allow easy connection flexibility for both lab and rack systems.
Engineered for Performance and Reliability
Compact, durable, and feature-rich, the LD400 Series DC Electronic Load is a trusted tool for testing, verification, and validation of DC power sources. Its precision, connectivity, and versatility make it an essential addition to any advanced power testing setup.
