Steca PA 15

The Steca Tarom and Power Tarom charge controllers send out signals (125 kHz on 300 Baud) which are modulated on the DC cable and received by the Steca PA 15 remote control.

These signals contain information on the batteries' state of charge (SOC). The Steca PA 15 features five different operating modes (see below) which can be set using five different jumper positions. The maximum switching capacity of 15 A can be increased with a Steca PA EV200 DC relay to up to 200 A if desired.
