ALx Series
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.
There are 27 different models in the ALx Series spanning power levels: 1.25 kW, 2.5 kW, 5 kW, 7.5 kW, 10 kW, 12.5 kW, 15 kW, 17.5 kW, 20 kW.
