Railway Transformer NTT 400 D
On-board power supply transformer for roof mounting Description The REO on-board power supply transformer NTT 400 D is designed for on-board power supplies that are fed by the on-board power converter (BNU). The transformer NTT 400 D refers to the complete, ready-to-operate unit with transformer, support frame, and housing. The transformer serves to adapt the voltage and for galvanic isolation of the pulse-width modulated intermediate circuit voltage and the consumers of the on-board power supply. 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) in a container. This guarantees that REO transformers are optimally aligned for your application. Maximum service life, cost/benefit optimization, and safety are the focus of our development. Customized complete solutions On-board power supply transformers can be custom-designed.
