Protect RCS TPRe TD Thyristor-based 3 phase rectifier and charger system


The Protect RCS TPRe TD battery charger system has been developed and designed to provide high reliability power supply and battery charging capability. Its characteristics have been optimized to secure power for the applications linked to transmission and distribution of electricity. The Protect RCS TPRe TD system is a thyristor-controlled rectifier suitable for charging nickel-cadmium or lead-acid batteries while supplying DC loads. It can also be used without batteries as a direct power supply. Its design is optimized for T&D (Transmission and Distribution) applications.


  • Type 3-phase Rectifier
  • Input Voltage 380V/400V/415 Vac
  • Output Voltage 24/36/48/60 & 110/127/220 Vdc
  • CABINET SIZE (HxWxD) 1310x600x600 mm

The rectifier is built inside a compact cabinet and can be equipped with optional items such as distribution breakers, blocking diode, communication ports etc. The cabinets are floor mounted and optimized to offer natural cooling on most of the ratings. The batteries are mounted in free-standing racks or in cabinets separated from the rectifier.
