Questions

Question
Bonjour je possède une maison alimentaire en monophasé 220 volts.
J'aimerais alimenter une pompe à chaleur triphasé à partir de mon monophasé, est-ce que votre produit est capable de faire la conversion du 220 volts au 380 volts pour une pompe à chaleur de 2500 Watts ?

Merci de votre aide.
Answer

Bonjour,

Vous disposez d'une ligne électrique triphasée et souhaitez alimenter une pompe avec une tension triphasée ?

Nous sommes désolés mais nous n'avons pas de transformateurs pour passer du monophasé au triphasé. Nous disposons d'équipements pour convertir le triphasé en monophasé.

Nous restons à votre disposition pour toute question complémentaire.

Question
Hola podría utilizar un inversor de estos para una instalación FV trifásica con puerto de generador e inyectarle la monofasica de un eólico que tiene un inversor de 3000 w en monofasico y convertirlos en trifasico para darle entrada al FV trifasico por la entrada del generador y así poder alimentar las baterías del inversor trifasico
Sería viable con este transformador o sería mejor un variado de frecuencia
Answer
Buenos días.
 
El producto al que hace referencia es un autotransformador trifásico 230/400 Vac 2 KVA soporta una carga de 1,4 KW, el fabricante recomienda dimensionarlos un 20 % por tanto no debe ser sometido a una carga mayor de 1,12 KW, a la salida del transformador hay que instalar un elemento decorte que esté en función con la intensidad máxima que es capaz de soportar.   Siempre y cuando el transformador reciba la tensión  e intensidad para la que está diseñado, hace su función.
 No obstante, verifique qeu cumpla con sus especificaciones.
 
Saludos
