Steca PA 15
Remote Control
Tarom and Power Tarom charge controllers send out signals
(125 kHz on 300 baud) which are modulated on the DC
power line and received by Steca PA 15 remote control.
These signals are information on the state of charge (SOC)
of the battery. No additional cabling is required. The PA
15 has five different operation modes adjustable by five
different jumper positions. The limited switching capacity
of 15 A can be increased by an optional Steca PA EV200
DC relay up to 200 A.

Steca Solsum VC
Voltage Converter
Especially solar home systems of 12 V or 24 V require
smaller voltages to supply loads as radios, cassette recor-
ders or mobile phones. The Solsum Voltage converter is
designed for supplying a large range of consumer elec-
tronics with capacities below 1.5 A and voltages below
12 V.
Features
Five field adjustable output voltages from
3 V to 12 V by jumper
High input voltage range from 5 V to 30 V
Screw terminals allow universal use
Low own consumption
Electronic Protections
Overtemperature protection
Overload protection
Polarity reversal of battery
Short circuit protection
Displays
LED 1: green - PV system LED; shows if voltage con-
verter is operating
LED 2: red - alarm LED; wrong polarity
