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 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 units is 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.
