Marcus Transformers 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
