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 1.6 m
2
● Suitable for use with open-close- or three-position controllers.
● We recommend a minimum pulse length of 500 ms on rotary actuators operated with
3-point control to ensure continuous and accurate operation.
Functions
Function Description
Control type Open-close-( SPST / SPDT) or three-position
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 The feedback potentiometer can be connected to external voltage to indicate the
position.
Auxiliary switch The switching points for auxiliary switches A and B can be set independent of
each other in increments of 5° within 0° to 90°.
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.
