All TECHLINE actuators have been tested in accordance with EN55011 class B (2007) (CISPR 11)�
A 1 m cable has been used in the test set-up�
Actuator without H-bridge
1) For normal operation the following is valid:
• Radiated emission requirements are met�
• Conducted emission requirements are met� However, to meet with these requirements a capacitor has
been mounted across the motor wires outside the actuator, and tests have then been made with this
capacitor� Capacitor values for some of the TECHLINE actuators can be found in the scheme below�
To comply with EN55011 class B (2007) a capacitor must be added across the motor wires, or the
connected control box must have similar/better filtering� The actuator is not delivered with a built
in capacitor, because then it would not be possible to PWM the motor for those who would want
to do that�
Please view the scheme below for the correct choice of capacitor for the actuator in question�
2) For systems/operations that use PWM-control it is up to the customer to test and meet the requirements�
Actuator with H-bridge
1) For normal operation with soft start/stop the following is valid:
• The actuator has been tested when operating with constant 80%-PWM�
• Radiated emission requirements are met�
• Conducted emission requirements are met�
2) For systems with LINAK PWM regulation (among other things parallel operation and speed regulation)
the following is valid:
• Radiated emission requirements are met�
• Conducted emission requirements are met�
3) Speed regulation:
• If the speed is regulated below a nominal speed of 80 % (80 %-PWM), it is necessary to mount a filter
in order to comply with the conducted emission requirements� For systems/operations that are speed
regulated, it is up to the customer to test and meet the requirements�
