Railway Transformer NTT 400 D
Onboard power supply transformer (Roof mounted) DESCRIPTION The REO transformer NTT 400 D is designed for onboard power supplies, which are fed by the auxiliary converter. The transformer NTT 400 D is the complete, ready to use-unit with transformer, mounting frame and housing. The transformer 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.

Air Choke Ld 220
Air choke with aluminium copper/disc winding DESCRIPTION Air reactors are particularly used where high inductive linearity is required. Due to their relatively simple mechanical structure, they are not only compact, but also very robust. With our expertise, the REO air reactors perform to the required standard, even in the most arduous conditions. REO Mix & Match principle With REO Mix & Match you can choose from a wide range of of options – combine the various options in order to always get the best product for your application. REO is able to offer different designs and winding techniques, a variety of conductor materials and structures. Depending on the specific requirements, we are able to produce an optimal solution by combining these parameters to provide the perfect solution. Optional Layer winding/Disc winding Aluminium, Copper or aluminium + copper Protections: Paint coating, protective coating, housing or REO Xtreme Cooling fan/unit Sensors: Switch NO / NC, PT100, NTC, PTC ADVANTAGES No saturation Wide range of material selection Special protective coating High linearity L (i) Very good mechanical strength No hysteresis Optimal weight by forced air cooling Directional air flow through GRP conduits Very efficient liquid cooling option (waveguide) Can be used almost anywhere PTC Technical Data Frequency of the current: DC and AC Tolerances: + 10 / – 10 %, + 5 / – 5 % Taps: By default, no taps (available on request) Insulation: F or H Cooling method and cooling liquid according to IEC 60310: AN, AF or WF Test voltage: up to 12kV 60s 50Hz, up to 25kV 1,2/50µs Mounting: Suspended, vertical or horizontal Mechanical strength, mechanical simulation (FEM): EN 12663 Shock – and vibration stress: IEC 61373 Kat. 1 Kl.
