DC Current/Voltage Injection Test Set High DC current injection set to 5,000 amps

The LET-4000R is designed to perform high current DC injection test, used mainly in the railway industry to test extra fast relays used in the electric motors of a locomotive. The unit is supplied in two modules: the Regulation and Measurement Module and a AC/DC converter.

Regulation and Measurement Module performs the regulation of the DC current and is made with a variable auto transformer (Variac) regulating a three phase DC current with a power of 8KVA and a three-phase transformer of 8KVA with 2 volt nominal power in the secondary windings. A built-in ammeter and a timer give the information of the current injected and the operation time of the relay under test.

AC/DC Converter Module rectifies the Alternating Current (AC) to work with the above mentioned unit. The signal is rectified in a complete sine wave. The output are in two taps adequately dimensioned. This unit also contains the measurement shunts, which gives the measurement value to the ammeter located in the other module.
