NC, RNC series

Product catalog summary
Introduction
The document discusses asynchronous frequency converters, which are electric rotating machines composed of an asynchronous motor with a cage rotor and an asynchronous generator with a wound rotor. These converters transform electrical energy at mains frequency into energy with a higher frequency, used to power high-frequency motors and other devices.

Specifications
The converters are available in NC and RNC series. In the NC series, excitation is supplied to the generator stator terminals, and the output voltage is available at the slip-ring terminals. In the RNC series, excitation is supplied at the slip-ring terminals, and the output voltage is available at the generator stator terminals, suitable for low output voltage and high output current needs.

General Characteristics
- Power range: 2.5kVA to 27.5kVA
- Input frequency: 50Hz - 60Hz
- Output frequency: 60Hz to 480Hz
- Insulation class: H
- Protection degree: IP54
- Long-duration ball bearings, life-long lubricated
- Protective cover for slip-ring and brushes for easy maintenance

Electrical Characteristics
- Rated current Ia is the sum of motor rated current Im and excitation rated current Iexc.
- Voltage accuracy: +10% in no-load, -5% in full load.
- Frequency accuracy: -0.5% to 0% in no-load, -1% to -3% in full load.
- Output voltage is perfectly sinusoidal (T.H.D. <1%).
- Short circuit current: Icc > 6In for output, Icc > 4Ia for input.

Criterion for Choosing a Converter
The converter power (in kVA) should be equal to the sum of the powers of the motors (in HP) fed by the converter, increased by 25%.

Data Tables
The document includes tables with detailed specifications for various models, including power, noise, and weight.

Overall Dimensions
Dimensions for NC and RNC series are provided, with technical data subject to change without notice.

NC, RNC series-1

Energy as an aptitude. Anyplace. Convertitori di Frequenza Frequency Converters Convertidores de Frecuencia Convertitori di Frequenza Asincroni Trifase Three-phase Asynchronous Frequency Converter Convertidores de Frecuencia Asincrònos Trifasicos Il convertitore di frequenza asincrono è una macchina elettrica rotante costituita da un motore asincrono con rotore a gabbia e da un generatore asincrono con rotore avvolto, coassialmente accoppiati. The asynchronous frequency converter is an electric rotanting machine consisting of an asynchronous motor with cage rotor and by an asynchronous generator with wound rotor, coaxail coupled El convertidor de frecuencia asincrónico es una máquina eléctrica rotatoria integrada por un motor asincrónico con el rotor de la jaula y por un generador asincrónico con el rotor bobinado, coaxialmente juntados. I convertitori realizzano la trasformazione dell’energia elettrica a frequenza di rete in energia elettrica a frequenza superiore, permettendo l’alimentazione di motori ad alta frequenza o apparecchiature industriali in genere. Converters transform the electric energy at mains frequency in energy with higher frequency, and they are used to feed high-frequency motors and other devices Los convertidores realizan la transformación de la energía electrica de la frecuencia de red en energía de frecuencia más alta, y se utilizan para alimentar los motores de alta frecuencia y otros dispositivos. Nella serie NC l’eccitazione è fornita ai terminali dello statore del generatore, e la tensione d’uscita alla frequenza trasformata è prelevabile ai terminali del collettore. In NC series converter, the excitacion is supplied on generator stator terminals, and the output voltage at the transfomated frequency is available on the slip-ring terminals. En los convertidores de la serie NC, la excitación se provee en los terminales del estator del generador, y el voltaje de salida en la frecuencia transformada está disponible en los terminales del colector. Nella serie RNC invece l’eccitazione si porta ai terminali del collettore, e la tensione d’uscita si preleva dallo statore del generatore: questa è la soluzione più indicata quando si necessita di basse tensioni in uscita (e conseguentemente, alte correnti in gioco). In RNC series instead, the excitacion is supplied on the slip-ring terminals, and the output voltage is available on the generator stator terminals: this is the suitable solution when you need a low output voltage (and so, a high output current) En la serie RNC, en lugar de otro, la excitación se provee en los terminales del colector, y el voltaje de salida está disponible en los terminales del estator del generador: esta es una solución más adecuada cuando usted necesita un bajo voltaje de salida (y por eso, una alta corriente de salida)
