Programmable DC Load | ALx Series

Magna Power ALx Series
Programmable DC Load with wide operating range
up to 20 kW 1Ph, up to 1000 V, up to 4800 A, CC, CV, CP, CR, SR

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’ air cooling ensures long product life with continuous full power operation in environments up to 50°C ambient operating temperature.

The ALx Series uses MOSFETs for power dissipation, delivering among the industry’s widest full-power operating range for its product class. The ALx Series uses MOSFETs 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 and have safe operating curves well below the maximum power rating when used as an electronic switch. Control circuitry for ALx Series MagnaLOADs are operated 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.
