STECAMAT 862<br />
Processor-controlled charger for lead-acid<br />
batteries with communication feature<br />
The battery charger <strong>Steca</strong>mat 862 charges the battery gently and quickly<br />
thanks to a processor-controlled charging process. The <strong>Steca</strong>mat 862 thus<br />
enables the processing of damaged or totally discharged batteries, ensuring<br />
long service life. The IP 65-certified dust and splash-proof housing allows<br />
for outdoor installation. Data can be read and processed centrally thanks<br />
to the integrated RS-485 interface. With this communication interface, the<br />
various charging parameters can be adjusted and the charging current can be<br />
increased to a maximum of 35 A. The integrated interface allows for communication<br />
with buses that are equipped with an integrated bus identification<br />
module (BIM).<br />
