Linear actuator Insolis 3
Description and applications
The actuator for solar photovoltaic
systems
With the developed Insolis 3 linear
actuator, elero Linearantriebstechnik
offers reliable drive solutions for users
of solar photovoltaic systems.
Twenty years of motor engineering
experience and proven solutions for
façade architecture and mechanical
engineering have contributed to the
development of the Insolis 3 linear
actuator.
The actuator has been specially developed for solar photovoltaic systems
(Elevation and Azimuth). This combination significantly increases the
efficiency of complex solar tracking
systems and ensures a quicker
amortisation of investment costs.
elero and solar systems –
a perfect combination!
Insolis 3 actuators are ideally suited
to the requirements of solar tracking
systems.
With a static holding load of as much
as 60,000 newtons with dynamic
forces of as much as 10,000 newtons
it aligns plants in accordance with the
position of the sun and keeps them in
position.
The housing of the Insolis 3 is protected as standard to IP 65 against the
entry of dust and is also hose-proof
and maintenance-free.
Eight actuator versions (24V DC and
230V AC) are available. Linear actuators with (adjustable) electronic limit
switches offer various advantages.
For instance, they allow for the adjustment of different stroke lengths
and provide overload protection.
230V AC actuators with RS-232
interface are available on request.
Also there are versions with encoders
for position feedback.
Insolis 3 actuators are fitted with sophisticated technology. They combine
long service life with highest quality
“Made in Germany”.
Benefit from our know-how for the
optimum use of solar energy!
User advantages:
– Extremely high static loads compared
to required dynamic loads
– Corrosion resistance over long periods
– Very high reliability
– Modular system, flexible integration
into existing and new systems
– Maintenance-free throughout the
entire service life
– High cost-effectiveness
Special advantages of actuators
with electronic limit switches:
– Electronically adjustable limit
switches
– Integrated overload protection
– Stepless adjustment of different
stroke lengths

Cable lengths from 1.5 m to 10.0 m are available on request.
All technical data represent average values and are based on an ambient temperature of 20 °C.
During installation please observe that the piston rod has to face upwards and that the PG cable glands on the actuator tube have to
face downwards. Prior written approval from the manufacturer is required for differing mounting positions.
Protective systems for actuators with electronic limit switches
Internal limit switches
The internal limit switches ensure that the piston rod moves between two adjustable end positions.
Undervoltage protection
The actuator is switched off if the voltage drops below the admissible operating voltage.
Overload protection
The actuator is switched off if the maximum dynamic load of 10,000 N is exceeded.
This protective system must not be used as a limit switch system.

Feedback signals
The limit switch feedback uses potential-free
relay contacts in case of versions 2 and 3.
The maximum ohmic load of these contacts is
24V/1A.
Digital outputs (24V DC) are used for the
adjusted end position in case of version 4.
The maximum load of these outputs is 20 mA.

Biaxial tracking movements
Movements of solar modules
Biaxial tracking systems offer the highest
efficiency. This means that the tracking
movements take place in two planes:
“Elevation” refers to the vertical movement,
while “Azimuth” refers to the horizontal
movement.
The Insolis 3 linear actuators can be used
for Elevation and Azimuth.
