Gamme d’alimentations à découpage 12DC, 24VDC ou 48VDC.

Montage sur rail DIN : nos alimentations se montent facilement sur les armoires électriques ou tableaux électriques.

Alimentation continue : courant continu et alternatif

Une alimentation électrique a pour but de transformer une tension alternative en tension continue et généralement d’abaisser celle-ci.

Courant continu ou alternatif ?

Le courant continu ou CC est un courant où les électrons circulent dans la même direction (du pôle positif vers le pôle négatif). L’autre type de courant est le courant alternatif (CA) où les électrons circulent dans les deux sens du circuit.
Le courant continu est privilégié en électronique et pour les machines fonctionnant sur batterie tandis que le courant alternatif est avantageux pour transporter l’énergie.

Pour créer une tension continue à partir d’un courant alternatif, vous pouvez utiliser les alimentations continues Technic-Achat. Nos alimentations transforment l’alternatif (220V monophasé ou 380V triphasé) en tension continue : alimentation 12v, alimentation 24v, alimentation 48v.

Vous trouverez toute une gamme d’alimentations électriques permettant de :

  • Transformer le 220V en 12VDC
  • Transformer le 220V en 24VDC
  • Transformer le 220V en 48VDC
  • Transformer le 380V en 24VDC

Les différents types d’alimentations électriques

Il existe deux catégories d’alimentations : linéaire et à découpage.

L’alimentation linéaire approvisionne une tension continue stable en contrôlant le courant fourni. Ces alimentations sont donc choisies lorsque la charge est sujette aux parasites. Elle est principalement utilisée en laboratoire.

L’alimentation à découpage assure la régulation électrique par des composants utilisés en commutation, comme des transistors (composant à trois bornes permettant de contrôler un courant).
Les alimentations à découpage sont utilisées dans les appareils sur batterie comme les ordinateurs portables, les chargeurs de téléphone, les caméras de surveillance…
