Features
Air damper actuators in difficult operational conditions; they meet the main requirements for:
● EN 50155 (Railway applications - Electronic equipment used on rolling stock)
● EN 45545 (Railway applications - Fire protection on railway vehicles)
● EN 61373 (Railway applications - Rolling stock equipment - Shock and vibration tests).
Use
The damper actuators are expressly suitable for air conditioning units and air distribution
systems for railway vehicles.
● For damper areas up to 0.8 m
2
● Suitable for use with modulating controllers (DC 0/2…10 V).
Functions
Function Description
Control type Modulating control (DC 0/2…10 V)
Rotary direction Clockwise / counter-clockwise, selectable with switch.
With no power applied, the actuator remains in the
respective position.
Position indication: Mechanical Rotary angle position indication by using a position indicator.
Position indication: Electrical Position indicator: Output voltage U = DC 0/2...10 V is generated proportional to
the rotary angle.
U depends on the rotary direction of the DIL switch setting.
Manual adjustment The actuator can be manually adjusted by pressing the gear train disengagement
button.
Rotary angle limitation The rotary angle of the shaft adapter can be limited mechanically with a set
screw.
Technical design
Housing
The housing consists essentially of flame retardant, non brominated, non chlorinated glass
fibre reinforced plastic.
Actuator motor / Gears
Brushless, robust DC motors ensure reliable operation regardless of load. The damper
actuators do not require an end position switch, are overload proof, and remain in place up
on reaching the end stop.
The gears are maintenance free and low noise.
