Lutgun international LLC has been official distributor of Marcus Transformers since 2016.  Marcus provides custom products for special "sensitive" applications, such as extra quiet, lowest temperature rise, low impedance, smallest footprint, etc. We offer blanket releases for just-in-time deliveries. Most of our transformers are "installer-friendly", both to connect and to mount. All transformers are manufactured in our factories in North America. Marcus Transformer models meet the following agency standards (where applicable): UL, CSA, CUL, CE. Our testing laboratories are certified by CSA and are therefore compliant with ISO/IEC – 17025 to evaluate and manufacture products to applicable standards 


If your application requires a special design not available in stock, Marcus will design, manufacture and deliver your custom-made transformer within 7 days of your request. And deliver to customers hand with fastest shipment.
