Silicon Rectifier
Entec's Traction Silicon Rectifier ETSR21 and ETSR22, as a crucial part in DC railway traction power system, are designed to convert AC power into DC power while withstanding the harsh operating condition in real application.
750V DC rated ETSR21 is mostly used for Light Railway Transit system and the capacity can be designed from 1000kW to 4000kW to suit different situations.
ETSR22, rated 1500V DC, is designed to be used in Metro System where the load requires a higher voltage level. The capacity of this Traction Rectifier can also be customized to apply to different systems.
