7 FUNCTIONAL DESCRIPTION

The Protect RCS TPRe TD rectifiers are thyristor-controlled rectifiers suitable for charging nickel-cadmium or lead-
acid batteries while supplying DC loads. The rectifier can be also used without batteries as direct power supplies.

7.1 OPERATING SEQUENCES

Rectifier with associated battery

Mains power ON – battery on floating



































The charger supplies the load (Ild) and delivers a "floating" charge current (Ifl) to battery BT.

Mains power ON – battery recharging



























 



 



 



 



The charger recharges battery BT at a high rate (Ihr) and supplies the load (Ild). The charger automatically switches
to "floating" charge (Ifl) when the battery is fully charged.
Thereafter the battery is kept in floating (Ifl).

Mains power OFF
















