SL Series Key Technical Specifications
Built on Magna-Power's signature current-fed topology for dense ATE integration, continuous full-power reliability, and high-efficiency power processing.
Defining a New Benchmark in 1U High-Density DC Power Supplies
Packs 1.5 kW to 10 kW of programmable DC power into an ultra-compact 1U rack-mount footprint, engineered for high-volume automated test equipment (ATE), OEM systems, and demanding laboratory research.
Current-Fed Topology
Utilizes an inductor-based DC bus to limit fault energy naturally. Delivers continuous short-circuit immunity, zero fast current spikes, and superior stability under dynamic load transients.
SiC Power Semiconductors
Advanced Silicon Carbide switches integrated with proprietary micro-channel heat sinks enable full continuous output up to 50°C ambient operating temperatures without thermal derating.
