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.

Typical applications
