Catalog excerpts

The ALT 72Vdc power supply range is used to supply the locomotives and carriages of different trains such as TGV, VB 2N, AGC. The power supply replaces the on-board network supply allowing the verification of the on-board electrical equipment and the lighting. It can be connected through an external 72Vdc connector designed for this purpose and has all required electrical protection necessary for the equipment being tested. Easy to use, the power supply is quickly installed and ready for operation. This power supply is proposed in two versions depending on the power required: - a mobile version which can be installed closed to the train - a wall-mounted version which can be installed in the maintenance shop.
