Harmann - automation - EVS electronic speed controller

Thyristor speed controller for single-phase (230 V, 50 Hz) motor (fan) controlled by 0-10 Vdc or 0-20 mA signal. It is used in voltage regulation of rotation in the motor in the fan in the range of 80-230 V. During installation, the minimum voltage should be adjusted to the safe value for the connected motor (second potentiometer under the cover, factory setting 80 V).

Technical data

• housing made of impact-resistant and UV-resistant ABS plastic in light gray
• surface mounting
• degree of protection IP54
• Separate LED button illuminated
• the minimum and maximum speed can be set using a trimmer
• the ability to convert the signal to 10-0 Vdc or 20-0 mA via an internal switch
• control of the engine (fan) speed by means of a MTV / MTP potentiometer or any sensor with a 0-10 Vdc or 0-20 mA control signal
• maximum working temperature 35 C

Modes of operation

• start at full load - after switching on or restarting the engine runs at full speed for a period of 10 s and then returns to the value set by the control signal
  
• soft start - after switching on or restarting, the engine works based on the value of the control signal
