Solar - Actuators from ZIMM
for precise, stable tracking using solar equipment
ZIMM has been involved in linear, electromechanical drive
systems for machine and plant construction for more than
30 years and can support you with professional competence,
the right products and expert advice.
The fact that insurance companies and solar park operators
know that a quality product is in use that avoids damage
and downtimes and therefore can possibly avoid higher costs,
will have a positive influence on the profitability analysis.
ZIMM is an international company from Vorarlberg - located
in Western Austria - and is a family business that has
developed into a global player and delivers its products all
over the world.
Our standard program with 3 sizes covers the variety of
differing expectations.
ZIMM has developed the ZSA series of solar actuators
especially for outdoor applications and meeting the
requirement for solar plants.
The actuators are designed and manufactured to be operated
for 20 years with a low maintenance requirement.
The actuators stand out with their robust and stable
construction and the usage of quality components.
Nevertheless, we can offer you an excellent priceperformance ratio through serial production and simple
installation - a lasting and excellent product.
Apart from that, ZIMM also offers further options and
products in the sector of ZIMM Screw Jack System,
produced for loads from 2 kN to 1000 kN.
We would be pleased to develop a concept for linear drives
suitable for your particular application, this means we
will examine your requirements and then offer you a
tailor-made solution, based on our standard program supplemented with your wishes.
We are looking forward to hearing from you.

General information on the actuator electronic
The ZSA-Actuator can be delivered with several electronic
assemblies. You can select between various operating
voltages and motor types. In addition, a product spectrum
of limit switches, rotary encoders and internal positioning
electronic are available.
The external electronic effort is minimized especially when
using an integrated positioning electronic system.
For larger quantities, we can adapt the electronic
features as well as the electronic software to meet
your requirements.
e.g. 24V DC Motor
with integrated end position switch-off and rotary encoder
e.g. 400V DC Motor
2x end position switches, mechanical
without integrated electronics
Preferred type!
The end positions of the actuator
are not overrun during proper
operation. Internal circuitry is
responsible here. This protects
the actuator from severe damage
caused should it overrun the end
positions.
ATTENTION:
Only actuator movement
between the two end position
switches is allowed.
The customer must provide
electrical control to prevent
any possible running over the
end position switches.
Moving to the hard stop will
severely damage the actuator.
Detailed technical information
available on request.
We therefore recommend the
variant with integrated end
position switchoff.
S1: End position switch extended
S2: End position switch retracted
M: Drive motor
Integrated positioning electronic
With the positioning electronic we can
simplify many applications. Due to the
fact that the complete electronic to
approach a desired position are integrated
in the actuator, only a few external
components are necessary, e.g. Solar
Tracker Elevations Sun Axes Tracking.

Pivot Brackets LB for Actuator ZSA
Pivot Brackets LB are made
of steel and they are protected
against corrosion. Designed for the full nominal load.
ATTENTION:
When planning your own design, please consider that not
only the axial loads but also the resulting bending forces on
the bolts must be absorbed by your design. Pivot Brackets
LB have been designed accordingly.
The bending forces are
absorbed by the Pivot Bracket.
Note:
Customer-specific pivot
brackets can also be
delivered on request.
