Railroad Transformer NTT 400
Auxiliary power transformer Description The REO on-board power supply transformer NTT 400 is designed for on-board power supplies that are fed by the on-board power converter (BNU). It serves for voltage adaptation and galvanic isolation of the pulse-width modulated DC link voltage and the consumers of the on-board network. A suitable sine filter must be connected between the Transformer and the inverter. The secondary-side load of the isolation transformer can be switching devices, rotating machines, ohmic loads, and semiconductor converter devices. The Transformers are designed for use in vehicles in AC or DC networks (in inverter operation) within a container. This ensures that Transformers from REO are optimally suited for your application. Maximum service life, cost-benefit optimization, and safety are the key priorities in our development. Customized complete solutions On-board power supply transformers can be custom-designed. Are you interested in this product? Please contact us! In addition to standardized components for use in converters, REO offers customized products – as a single component or as a complete solution in a container. The benchmark in railway technology is the availability and safety of passengers. Here, REO offers special solutions that are developed step by step in close cooperation with the customer.

Leakage Field Transformer RUT 500
Leakage Field Transformer Description Especially in the railway sector, where maximum comfort and safety for passengers are paramount, space-saving, safe, and durable components are required. Current dips or voltage losses can cause various undesirable effects, such as loss of motor power. The REO leakage field transformer ensures a harmonious progression of currents and voltages at the output, thus filtering harmonics and limiting ripple current. Due to the spatial separation of primary and secondary windings and the associated targeted increase of the magnetic leakage flux, the REO leakage field transformer achieves loose magnetic coupling. This combines the function of a transformer (voltage transformation and galvanic isolation) and a sine filter choke. Selection options Various power classes: 50 kVA, 100 kVA, 150 kVA, and 200 kVA Voltage drop uk 10%, 20%, and 30% Voltage ratio / windings freely selectable Winding freely selectable according to material and insulation class, and optimized for low eddy current loss Advantages Space-saving (Transformer and Drossel in one component) Longer motor life by limiting current peaks Cost-effective Optimized for railway operation (high degree of contamination, shock and vibration tested, salt spray and immersion bath tested) Technical data Rated power: 71000 – 275000 VA Input voltage: 210 – 1660 V
