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 primary current flow generates a magnetic flux, which is compensated by an internal secondary coil.The current evaluation is realized with an electronic circuit and a Hall sensor. The secondary compensation current is an exact reflection of the primary current to be measured. Unique Selling Point Measurement of direct, alternating and mixed currents Very high precision and short response time Broad frequency spectrum and low-temperature drift Very good linearity and overcurrent resistance No additional losses in the measuring circuit (DC to 150 kHz) Current output for lengthy transmission lines High-quality UL-listed insulating materials (e.g. UL94-V0) UNIQUE SELLING POINT Robust housing designs (for horizontal/vertical mounting) Variable connections, e.g. clamps, plugs, flat-cable plugs or cables Wide range of housings with various push-through openings Push-through openings Typical applications Industry, Renewable energy sources, Railway engineering, Energy, automation and building technology ELECTRICAL DATA Type WKO 25 WKO 50 WKO 100 WKO 300 WKO 500 WKO 1000 Primary RMS nominal current IPN [A] 25 50 100 300 500 1000 Measuring range IP [A] 0…±35 0…±70 0…±150 0…±500 0…±1000 0…±1500 Supply UC [V] ±12 …15 ±12 …15 ±12 …15 ±12 …15 ±12 …24 ±12 …24 Measuring accuracy XG@Ipn [-20…70°C] from IPN [%] > ±0,9 > ±1 > ±1 > ±1 > ±1 > ±1 Translation KN 1000 1000 1000 2000 5000 5000 Secondary RMS Nominal current ISN [mA] 25 50 100 150 100 200 Secondary winding Resistive sand RS@70°C [Ω] 16 43 24 30 72 48 Idle current [mA] 36+IS 11+IS 36+IS 36+IS 36+IS 24+IS ACCURACY AND DYNAMIC DATA Type WKO 25 WKO 50 WKO 100 WKO 300 WKO 500 WKO 1000 Linearity error e [%] < ±0,1 < ±0,1 < ±0,1 < ±0,1 < ±0,1 < ±0,1 Offset error@25°CIO [mA] > 0,3 > 0,3 > 0,4 > 0,2 > 0,2 > 0,3 Offset Drift-25°C…+70°CIOT [mA] > 0,5 > 0,5 > 1 > 0,5 > 0,5 > 0,5 Response time tra[μs] > 0,5 > 0,5 > 0,5 > 0,5 > 0,5 > 0,5 Response time 10%-90% ta [μs] > 1 > 1 > 1 > 1 > 1 > 1 dl/dt ta [A/μs] > 50 > 50 > 100 > 100 > 100 > 100 Bandwidth -1 dB [kHz] DC…150 DC…200 DC…100 DC…100 DC…100 DC…100 ISOLATION DATA Type WKO 25 WKO 50 WKO 100 WKO 300 WKO 500 WKO 1000 Creepage distance dCp [mm] 4 8 10 10 10 15 Air section dCi[mm] 3 7 9 9 9 12 Leakage current resistance [CTI] 600 600 600 600 600 600 AC insulation test 50/60Hz 1min Ud [kV] 3,8 3,8 3,8 3,8 6 6 Pulse voltage test 1,2/50μs Ui[kV] 6 6 6 6 12,5 14,5 Mass [kg] 0,08 0,022 0,125 0,125 0,240 0,450 Dimensions in mm Type Pin connection/ 4-pin h [mm] b [mm] b1/b2 [mm] t [mm] DL [mm] p/s [mm] a/a1 [mm] c1/c2 [mm] f [mm] e [mm] l [mm] WKO 25 A; -U; +U 39 39 – 26 10 – 2 x 10/6,5 25/6,5 M3 6,0 x 4,0 9 WKO 50 A; -U; +U Please find in the drawing WKO 100 A; -U; +U 55 – 55/68 26 20,2 45/45 – 13,0/– 4,3 6,0×4,0 12 WKO 300 A; -U; +U 55 – 55/68 26 20,2 45/45 – 13,0/– 4,3 6,0×4,0 12 WKO 500 A; -U; +U 70 – 70/89 33 31,0 57/57 – 15,2/– 4,3 6,0×4,3 12 WKO 1000 A; -U; +U 95 – 94/110 44 40,0 78/78 – 18,0/– 5,3 8,0×5,3 12 Data sheet Download our extensive catalog and discover many other REO products.

Active Current Transformer Series WDI
AC/DC Open loop current transformers Description Open loop current transformers The WDI current sensor is an open-loop current transformer designed for measuring direct and alternating currents. The primary current generates a magnetic flux and this is evaluated by means of a magnetic circuit and Hall sensor in the air gap. The signal from the Hall sensor is processed by an electronic circuit and an exact representation of the primary current is output as a voltage. Advantages (electrical) Measurement of direct and alternating currents Voltage output Low power consumption No additional losses in the measuring circuit High-quality UL-listed insulating materials (e.g. UL94-V0 Safe electrically isolated primary and secondary circuits Good price/performance ratio Advantages (mechanical) Low weight Robust housing designs (for horizontal/vertical mounting) Connections: clamps, plugs, flat-cable plugs or cables Wide range of housings with various push-through openings Typical applications Industry, Renewable energy sources, Railway engineering, Energy, automation and building technology Technical specification Type 25 150 300 Primary rated current [A] ÎPN Peak 25 150 300 Max.
