Magna Power ALx10-500-1000/240SP+LXI DC Electronic Load

Overview

The Magna Power ALx10-500-1000/240SP+LXI is a 10kW DC electronic load utilizing conventional linear MOSFET-based dissipative elements to achieve a very wide voltage-current operating range within the model's maximum power rating. Using the same heat management innovations developed for Magna-Power's high density programmable DC power supplies, the ALx Series' conservative cooling ensures long product life with continuous full power operation in environments up to 50°C ambient operating temperature.

Technology

The ALx Series uses MOSFETs for power dissipation, delivering among the industry's widest full-power operating range for its product class. MOSFETs are specifically selected based on their ability to operate in the linear region and have safe operating curves well below the maximum power rating when used as an electronic switch.

Control circuitry for ALx Series MagnaLOADs operates in a closed loop to linearize the response. Each MOSFET device produces a load current defined by VC/Rn. Closed loop amplifiers enable multiple MOSFETs to share load current equally.

Applications

• Battery testing and characterization
• Power supply burn-in and validation
• Thermal stress testing of power devices
• Power conversion efficiency testing
• Load simulation for electrical system testing
