REO-USA

What REO-USA does

REO-USA, Inc. is a wholly-owned North American subsidiary of the German family-owned parent REO AG (founded 1925 in Berlin). Operating from Noblesville, Indiana with 11–50 employees, the company manufactures and distributes inductive, resistive, and electronic components including resistors (REOhm brand), transformers, reactors/chokes, EMI and harmonic filters, power controllers (REOTRON), current transformers, and electrical testing equipment (REOLAB, REOLOAD, REOLINE, REOCHOKE). The company also sells the REOVIB line of vibratory feeder control units and provides customized development services for application-specific power electronics solutions.

Underlying technology centers on proprietary techniques such as REO EDGE-Winding (reducing skin and proximity losses for SiC/GaN semiconductors), liquid cooling integration (1–100 kW resistor capacity enabling up to 80% size reduction), harmonic filtering (REOWAVEpassive achieving <5% THD and up to 30% energy savings), sine wave filters enabling 1000m motor cable lengths, and dv/dt filters limiting voltage rise to <500 V/µs. Products hold extensive certifications including UL, UL1283, VDE, EN 61558, EN 45545, EN 60310, EN 50155, and IEEE 519 compliance.

The business model is hardware-led direct sales with quote-based pricing, supplemented by customized engineering services, in-house repair/RMA support, and on-site REOVIB training. The company sells across at least eight verticals — industrial manufacturing (primary), medical technology, e-mobility, railway, renewable energy, marine/offshore, defense, and test/measurement — relying on its parent's international subsidiary network for cross-border reach while manufacturing remains concentrated in Germany.
