PROTECT RCS TPRe TD

The Protect RCS TPRe TD battery charger system has been developed and designed to provide high reliability power supply and battery charging capability. The Protect RCS TPRe TD is a thyristor-controlled battery charger suitable for charging nickel-cadmium or lead-acid batteries while supplying DC loads. Its design is optimized for T&D (Transmission and Distribution) applications.

The rectifier is fitted inside a very compact cabinet and can be equipped with optional electrical and mechanical items in order to comply with most of the T&D specifications. It can also be connected to an inverter in order to deliver a safe AC supply.

The cabinets are floor mounted and can be customized to meet specific environmental requirements. The batteries are mounted in free-standing racks or cabinets.
