Steca ULED 11
Energy-saving light
Steca ULED 11 is optimally suited for small applications as
the 1.1 W LED has very high efficiency. The stable glass-cera-
mic housing means that it can even be used in critical envi-
ronments. 18 single warm white LEDs form a good and well
recognized color.

Accessories for
Steca PR 10-30, Steca Solarix MPPT, Steca PR 2020 IP,
Steca Solarix 2401/4401 and Steca Tarom
Steca PA TS10, Steca PA TSIP10
and Steca PA TSK10
External temperature sensors
The Steca PA TS10, Steca PA TSIP10 and Steca PA TSK10
external temperature sensors are used for monitoring the
battery temperature.
All Steca solar charge controllers have an integrated tem-
perature sensor that makes them capable of adjusting the
charging strategy to suit the current temperature conditions.
The Steca PA TS10, Steca PA TSIP10 and Steca PA TSK10
external temperature sensors are only required when the bat-
tery must be installed in a different room to the solar charge
controller.
The Steca PA TS10, Steca PA TSIP10 and Steca PA TSK10 are
supplied with a plug for connection to the solar charge con-
troller and ring eyelets for connection to the battery screw.
The external temperature sensors are suitable for use with
Steca PR 10-30, Steca Solarix MPPT, Steca PR 2020 IP, Steca
Solarix 2401/4401 and Steca Tarom solar charge controllers.

Options for Steca solar
charge controllers
Optional alarm contact
Steca solar charge controllers provide alarm contacts which
allow to process this information in any other application. In
case of an alarm such as low battery voltage, over tempera-
ture, overvoltage or other alarms a signal is processed which
can be used for any purpose. The alarm codes are different
among the Steca solar charge controllers. Each controller has
its own alarm code table. In case an alarm is active either
a 5 V signal to ground is active on the alarm contact or a
galvanic isolated switch is closed. As soon as the alarm is no
longer active the signal goes back to 0 V. The following table
provides an overview on the available alarm options for Steca
solar charge controllers.
