NTT 500 Leakage Field Transformer
Especially in the railway sector, when it comes to maximum comfort and safety for passengers, space-saving, safe and durable components are required.
Railway Transformer NTT 400
Onboard power supply transformer Description The REO on-board power transformer NTT 400 is designed for on-board power supplies that are fed by the on-board power converter (BNU). It is used to adapt the voltage and for galvanic isolation of the pulse-width modulated DC link voltage and the consumers of the vehicle electrical system. An appropriate sinusoidal filter must be connected between the transformer and the inverter. The secondary-side load of the isolating transformer can be switching devices, rotating machines, resistive loads and semiconductor converter devices. The transformers are designed for the use of vehicles in the AC or DC grid (in inverter mode) in containers. This guarantees that transformers from REO are optimally designed for your application. Maximum service life, cost/benefit optimization and safety are the focal points of our development work. Customer-specific components On-board power transformers can be customized. Are you interested in this product? Please contact us! In addition to standardized components for use in converters, REO offers customer-specific products – as individual components or as a complete solution in a container. The benchmark in railroad 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.

Stray field transformer RUT 500
Leakage Transformer Description Particularly in the railway sector when the highest possible level of comfort and safety for the passengers is important, space-saving, safe and long-lived components are essential. Current dips or voltage losses can cause various undesirable effects, such as loss of motor power. The REO leakage transformer ensures harmonized current and voltage outputs, filtering harmonics, and limiting the ripple current.With the spatial separation of the primary and secondary windings and the resulting intentional increase in the magnetic leakage field, the REO leakage transformer achieves a loose magnetic coupling.This results in the combination of the function of a transformer (transforming voltage with galvanic separation) and a current-limiting choke. Options Various performance classes: 50 kVA, 100 kVA, 150 kVA and 200 kVA Voltage drop 10% UK,20%, and 30% Voltage ratio /Windings selectable Winding material and optimized insulation degree selectable Advantages Space-saving (transformer and choke in a single component) Longer life for motors by limiting of current peaks Low-cost Optimized for railway operation (high degree of pollution , Shock- and vibration tested ,Salt spray and immersion tested) Technical specification Rated power: 71000 – 275000 VA Input voltage: 210 – 1660 V
