Buck converter chokes NTT UI114-50
REO TSS reactor with iron core Description The buck converter reactor as an inductive passive component in the power supply and in power electronics is used to attenuate unwanted frequencies or for saving energy and storage. The term buck-converter reactor indicates the complete ready-for-use unit containing the choke, air cooling, mounting and connections. The reactors are available with different cores, which enables individual selection depending on the requirement of the application. In addition to iron-based cores, reactors with cores of amorphous alloy are becoming more common, in the form of toroidal cores, cut strip-wound cores or special custom solutions. The use of amorphous materials offers an exceptional combination of high saturation flux density (1.56 T) and a high permeability. In addition to the high temperature class, further features of amorphous alloy include low hysteresis and eddy-current losses, suitability for the medium-frequency range (<20 kHz) and use for high powers up to 500 kVA. Advantages Lower losses in comparison with grain-oriented sheet Can be used in the kHz region Equal or higher power ranges with smaller components Significantly lower weight High flux densities Usable up to temperature class H (180°C) Protection class IP 65 Technical Data Type of reactor: Up/Buck converter reactor with iron core Voltage of the system: 500 – 1100 V Max. permissible tolerances: ( -10 % / +10 % ) Linearity: min. 0.2 mH @ 230 Aeff Harmonic currents constantly / Superimposed Harmonics: 60 Ass @ 19 kHz Insulation class: H Cooling: AF Protection rating: IP65/66 Rated voltage for insulation: 1200 Vdc Test voltage: 3.5 kV (50 Hz, 60 s) Technical specification Voltage [V] 500 – 1100 Rated current [A] 120 Linearity @230 A [mH] min. 0.2 @ 230 Aeff Nominal inductance[mH] 0,2 Resistance [mΩ] 3,7 @ 20°C/ 5,1 @ 120°C Losses [W] ≤ 170 W @ 120°C Cooper [kg] 4,4 Weight [kg] 17,4

Motor Choke N CNW 854
Three-phase motor choke Description Compact & Efficient The new series not only scores points for its faster delivery time, but also for its resource conservation and increased efficiency. Reduce voltage rise (< 200V / µs) and distortions – optimally protect electrical consumers. In addition to voltage rises, there is a considerable amount of symmetrical and asymmetrical current distortions generated at the motor supply line due to the rapid switching of power semiconductors. These become more pronounced with increasing cable length. These disturbances can affect the motor’s performance through loud noises and, in extreme cases, through overheating. A motor choke can provide a remedy here. The motor choke reduces the voltage rise and voltage peaks between the conductors. Furthermore, the current is smoothed. Losses and heating are minimized and leakage current is reduced. Longer motor cable lengths can be used. The motor insulation is protected, thus increasing its lifespan. The motor choke also dampens conducted interference in the lower frequency range very well. Losses and typical noises in the motor laminations are reduced. Voltage rises are reduced to (< 200V / µs.) Increasing the service life of motors, lowering the edge steepness du / dt to earth and between the phases, reducing motor noise, and current smoothing. Advantages Protection for electrical consumers Limitation of voltage rise to < 200V/µs Extended service life of electrical consumers Reduction of engine noise Low leakage currents on the motor Longer motor cables are possible Easy construction Compact design Production possible according to UL insulation system E251513 TYPICAL APPLICATIONS Drive systems for motor drives, Mechanical engineering, Elevators / escalators, Pipes, Conveyor technology, Ventilation and air conditioning, Robotics, Automation technology, Power supplies, Wind turbines Technical Data Reduction of voltage rise du/dt to < 200V/µs Field frequency: 0 – 60 Hz Drive Switching frequency of the inverter: up to 150 A >4kHz, from 150 A >1.5kHz According to: EN 60289 / EN 61558 Test voltage: L-L 2500 V, AC/50Hz 60s; L-PE 2500 V, AC/50Hz 60s Insulation class: T40/F Protection rating: IP00 Climatic category: DIN IEC 60068-1 Overload: 1,5 x INenn 1 min / h Ambient temperature: 40 °C Design: standing on foot angle Technical specification Type Nominal voltage U [V] Nominal current I [A] Inductance L [mH] Losses P [W] Mass [kg] Mass Cu [kg] Mass Al [kg] N CNW 854 / 2 500 50 / 60 Hz 2 7,00 21 1,0 0,3 – N CNW 854 / 4 4 3,60 26 1,1 0,5 – N CNW 854 / 8 8 2,00 35 2,0 0,5 – N CNW 854 / 10 10 1,70 44 2,2 0,9 – N CNW 854 / 12 12 1,20 52 2,7 0,8 – N CNW 854 / 16 16 0,90 54 2,8 0,9 – N CNW 854 / 24 24 0,70 55 4,4 1,9 – N CNW 854 / 30 30 0,50 40 4,5 0,9 – N CNW 854 / 37 37 0,42 40 6,0 1,4 – N CNW 854 / 48 48 0,32 60 7,0 1,9 – N CNW 854 / 60 60 0,28 80 7,0 2,0 – N CNW 854 / 75 75 0,22 100 8,0 1,4 – N CNW 854 / 90 90 0,17 80 10,0 1,9 – N CNW 854 / 115 115 0,14 150 14,0 1,6 – N CNW 854 / 150 150 0,11 170 16,0 3,1 – N CNW 854 / 180 180 0,09 160 18,0 3,2 – N CNW 854 / 200 200 0,08 170 23,0 2,8 – N CNW 854 / 250 250 0,065 240 24,0 3,8 – N CNW 854 / 300 300 0,053 380 44,0 1,5 2,7 N CNW 854 / 350 350 0,046 330 55,0 2,6 4,6 N CNW 854 / 400 400 0,041 380 58,0 2,6 4,9 N CNW 854 / 500 500 0,032 520 63,0 2,6 5,2 N CNW 854 / 600 600 0,028 650 65,0 5,0 5,9 N CNW 854 / 700 700 0,024 820 86,0 5,0 5,7 N CNW 854 / 800 800 0,021 710 108,0 6,6 9,0 N CNW 854 / 900 900 0,018 800 114,0 13,8 7,6 N CNW 854 / 1000 1000 0,016 900 114,0 13,8 7,6 N CNW 854 / 1200 1200 0,013 1170 122,0 13,8 8,0 DIMENSIONS IN MM Type Length L1 [mm] Length L2 [mm] Width B1 [mm] Width B2 [mm] High max.

Harmonic Filter CNW 897
Three-phase harmonic filter (400 V / 50/60 Hz) DESCRIPTION The filter is designed for the reduction of the THD (Total Harmonic Distortion) when used with B12 rectifiers. The harmonic currents are extremely suppressed so that the THD is reduced to lower than 5 % (for example in UPS-systems).Typical values of Total Harmonic Distortion with B12 rectifiers and the use of transformers are between 12 and 13%. This complies with the EN 61000-3-4 and EN 61000-3-12 standards.If more severe conditions for the mains are defined, in addition to the transformer it is necessary to use REO-Harmonic-Filter type CNW 897. These filters are available in two different versions: THD < <5% THD < <10 % The IP00 version is especially suitable for panel mounting and can be mounted to save space here. The CNW 897 helps to comply with international power quality standards IEEE 519 or EN 61000-3.

du/dt Choke N CNW 806
Three-phase dv/dt filter DESCRIPTION NEW SERIES! The new series not only scores points for its faster delivery time, but also for its resource conservation and increased efficiency. Reduce voltage rise to < 500V / µs – protect electrical loads and insulation cost-effectively. A simple and cost-effective method to reduce the voltage rise rate is to use a du/dt choke or filter. It dampens the voltage rise to tolerable values and prevents overvoltages on long supply lines. Losses and heating are minimized, and the leakage current is reduced. By limiting the voltage steepness, the motor insulation is protected, thus extending its service life. EMC interference in the radiation range from 1 MHz to 30 MHz is also reduced.

DC-Link Choke N CNW 892
DC-link chokes (2 lines) Description Compact & efficient Reduce grid disturbances – save energy costs. The DC-link reactor is used for smoothing the DC link current and to reduce mains harmonics in voltage source inverters. The typical combinations of rectifiers and capacitors strains the supply network significantly. For functional reasons, the current consumption of the power supply or the inverter is not sinusoidal but pulsed at the moment of maximum voltage. DC-link reactor reduce the harmonics and relieve the supply network similar to the mains choke. In addition, the DC-link reactor attenuates charging current peak surges of the DC-link capacitors.
