Vertically integrated American manufacturing

We don’t just design power supplies; we make them.

At Magna-Power Electronics, we take immense pride in our complete control over the manufacturing process—every critical step happens under one roof. This degree of vertical integration is the product of over four decades of power electronics and manufacturing experience, spanning everything from custom magnetics winding to advanced surface-mount PCB assembly, all performed in-house. By merging hardware and software competencies, we ensure maximum scalability and continuous innovation across our broad product line, which now ranges from 1.25 kW to over 10 MW+. Our commitment to quality, backed by ongoing investments in state-of-the-art machinery and automation, has made Magna-Power Electronics a trusted name for robust, highly configurable programmable DC power supplies.

We invite you to explore our manufacturing departments through a series of videos, offering a behind-the-scenes look at how we transform raw materials into industry-leading power solutions. You’ll see how our dedicated engineering and manufacturing teams collaborate to uphold rigorous standards at every stage, from concept to final testing. This focus on craftsmanship and cross-department synergy is what enables Magna-Power to confidently stand behind every product we ship—delivering unmatched performance and reliability to customers worldwide.

Sheet Metal Department

The Sheet Metal Department transforms sheet steel, aluminum, copper, and fiberglass into finished components through processes starting with shearing to cut raw materials to size and multiple auto-tool-changing turret punch presses for creating detailed punch patterns. Metal sanding deburrs and prepares surfaces for powder coating, which includes an iron phosphate wash, ground plane masking, electrostatic powder application, and baking for a highly durable finish. A high-tonnage press brake provides accurate bending, while fastener insertion with automated vibratory bowl feeders ensures secure hardware placement. Adding further depth to this department’s capabilities is a robotic bonded fin heat sink assembly, featuring internally developed automation with a robotic arm and automated epoxy dispensing, as well as pad printing to finalize the completed parts.

Primary operations:

Shearing operations to cut sheets to size
Tool-changing turret punch presses
Metal sanding for deburring and powder coating prep
High-tonnage press brake for bending

Machining Department

The Machining Department brings raw materials to life through precision processes and equipment, using advanced CNC vertical machining centers—complete with extended tool magazines, auto-probing, and the capability for wet machining on copper, aluminum, and steel, as well as dry machining for insulating fiberglass. Milling of front panels, mounting holes for semiconductors in heat sinks, and the manufacture of various bus bar assemblies are all performed here with remarkable accuracy. For especially intricate components, Wire EDM employs a thin wire and controlled electrical discharges to produce complex shapes and tight tolerances. This department also handles welding of heavy-gauge steel for rack enclosures, a CNC horizontal machining center dedicated to high-voltage insulators, and comprehensive wood-working operations for custom packaging. Additionally, saw operations efficiently cut bulk metal to size for downstream processes.
