Description

DC Electronic Load

The ALx Series MagnaLOAD utilizes conventional linear MOSFET-based dissipative elements, allowing the series 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.
