Accessories for Steca Tarom and
Steca Power Tarom
Steca PA 15
Remote control
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 opera-
ting 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.
Product features

Steca PA EV200 DC
12 V / 24 V, 36 V / 48 V DC relay
The Steca PA EV200 relay increases the switching capacity of
the Steca PA 15 remote control from 15 A to 200 A (up to 10
kW). The relay is connected to the Steca PA 15 remote control
at the load output and, for example, interrupts the battery
voltage to a back-up generator when the end-of-charge vol-
tage is reached. The relay is hermetically sealed and operates
safely in difficult environmental conditions such as dust, salt
and moisture.
Product features
Low own consumption
Ready for connection to the Steca PA 15 remote control
