1-Phase High Voltage T/R Set

The ESP power supplies were introduced in 1970s & ever since have a good field-proven performance. They consist primarily of a Thyristor controlled power-circuit, wherein the firing of the Thyristor is controlled to provide a pulse-by-pulse control of the load current.  

The controlled firing of the Thyristors ensures a low ripple in the output.  

Majority of them operate at a fixed frequency of 50 Hz.   

Depending on the customer’s availability of power supply, Ador offers the flexibility of providing High  Voltage Transformer Rectifier units in both the Single-phase and Three-phase options. 

 Manufacturing range: 30 kV(P) to 200 kV(P) ; 50 mA to 4000 mA 

  • Versatile T/R set construction:
