Overview

What it does

Statcon Energiaa thyristor-controlled industrial battery chargers convert AC to DC to charge battery banks while supplying continuous DC loads.

They are available in natural-cooled and forced-cooled designs, with float, float-cum-boost, dual and redundant configurations.

Transformers are manufactured in-house and systems can be customised for special applications.

Float-cum-boost charger with dropper diodes
Dual float-cum-boost, and float plus float-cum-boost (FC + FCBC) systems
Multiple chargers with a redundant standby charger
Control circuit on glass epoxy board with digital and analog circuit blocks
High transient response under specified load and line variations
Class-F rectifier transformer, made in-house
Protections: AC under/over voltage, DC under/over voltage, overload, thyristor fuse, blocking diode, soft start, surge suppressor, short circuit
Customisation for special application requirements
