Converters for group soft start PAD-V-G (PSD-V-G)

photo_ss_groupOn November 16, 2010 quality mark «Ekaterinburg Quality» was assigned to voltage converters PAD-V and PSD-V manufactured by Automated Systems and Complexes CJSC according to Resolution No.10/3 of Coordinating Council for Product and Service Quality Assessment of Ekaterinburg city administration. 

 

Main functions:

  • Converters for group soft start of asynchronous and synchronous motors are used for successive start-up of several motors and their connection to the network. The motor to be started is selected by special motor selection cells (YVD). The number of YVD cells is determined by the number of started motors.

Application:

  • pumps, fans, compressors, air blowers and other mechanisms of centrifugal operational principle.
