| MULTIVOLTAGE STATIC FEEDER FOR RAILWAY CARRIAGE TESTING
DATA SHEET |
|
1.
Features
The purpose of the apparatus is to provide, from the mains voltage 400V,
the four voltages emploied on the european carriage: 3000Vdc, 1500Vdc, 1500Vac and 1000Vac 16,6Hz.
These voltages are stabilized and manually settable.
