Problem
Electrical projects often require low‑voltage dry‑type transformers that meet specific voltage, kVA, and environmental ratings, yet standard off‑the‑shelf units may not fit unique design constraints, leading to costly custom engineering and prolonged installation times.
Solution
MacKinnon Magnetics manufactures low‑voltage dry‑type transformers ranging from 15 kVA to 800 kVA with both aluminum and copper windings. The company provides a stocked inventory of standard models for rapid shipment and offers fully custom designs—including isolation, drive isolation, and harmonic‑mitigating options—to match project specifications. All transformers are built to NEMA 3R standards and feature an installer‑first enclosure with integrated lifting eyes, ventilated construction, and elevated mounting bases, reducing on‑site labor and handling effort. By combining ready‑to‑ship inventory with responsive engineering support, MacKinnon delivers reliable transformer solutions that align with project schedules and performance requirements.
Target Audience
Primary customers are electrical contractors, industrial facilities, and commercial construction projects in North America that require reliable low‑voltage dry‑type transformers for indoor or outdoor installations.
