Magna Power ALx12.5-1000-375/240SP+GPIB DC Electronic Load

Overview

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 50C ambient operating temperature.

Technology

The ALx Series uses MOSFETs for power dissipation, delivering among the industry's widest full-power operating for its product class. MOSFETs are operated in the linear region to allow full power and full control over the entire VA rating of the product.

MOSFETs are specifically selected based on their ability to operate in the linear region with 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, with closed loop amplifiers enabling multiple MOSFETs to share load current equally.
