Soft-starters for induction motors UPP1 (UPP1) and UPP2 (UPP2) series

     1-130-4 
 
     1-140-4

Soft-starters and stopping device UPP1(UPP1) and UPP2(UPP2) are designed as a thyristor switch devices (three-phase voltage regulators), which are provide soft start with switching on of the outer shunting contactor and stopping of the three-phase asynchronous electric drives with short-circuit rotor.

Devices UPP1 (UPP1) and UPP2(UPP2) combine functions of soft-start and stopping, machinery and electric drives protection, and of connection with automation systems.

Application area
  • Pump works, fans and compressors
  • Transfer conveyors and assembly lines
  • Heavy-loaded and inertial machinery
  • Grinding, metal- and woodworking machines, press-forging plant
  • Machines and machinery with belt, roller chain and other transmissions, reducing gear
Advantages
  • Provides starting moment setting
  • Reduces starter current
  • Reduces current losses after speed-up due to the shunting contactor
  • Enables multistage start of several electric drives by one smooth-start device
  • Improves operation conditions of the electric drive, start-protecting equipment and mains
  • Improved operating conditions of the motor, launch protection equipment and power supply circuit
  • Reduces service expenses
  • Control capability by interface devices RS232 and RS485
    

Technical characteristics

  Maximum starter current  75, 190, 300, 480, 750, 1200
  Mains voltage, V  380 +10%, -15%
  Mains frequency, Hz  50 Hz
  Insulate inputs   analogue and digital (2+3)
  Programmable insulate outputs   analogue and relay (opto-coupler) (2+4)
  Block protection class  IP00
 Ambient temperature  5...45
    Types of start:
  • Start with preset current limit
  • Motor start with continuous voltage increase and preset step
  • In-rush current start for obtaining a higher starting moment
    Types of stopping:
  • Stop with a given intensity
  • DC injection braking

Parameters of starting and stopping:

  Starting period  1 - 120 sec (shock-free start without starter current limitation)
  Stopping period   1 - 120 sec
  Current limitation  0,1-1,0 I-start
  Starter voltage  0,1 1,0 U-voltage of the cicuit. Determines the starting moment
  Pulse start   Pulse start is used for machinery with long period of starting. The effect is achieved by means of the initial voltage pulse.
  Pulse duration  0,1 - 1 sec
  Varying acceleration start   is used to prevent fast acceleration at the start ( backlash and other machinery) and for resonant zone avoidance

Protections:

  • overcurrent protection;
  • motor time-current protection;
  • Protection against overheating;
  • Protection of the thyristors failure;
  • Protection from the protracted start;
  • phase loss protection at the input of the device;
  • phase loss protection for the output of the device;
  • Protection from control system error
  • protection from abnormal frequency deviation of mains;
  • protection against inadvertent changes of settings.
  • Protection against voltage deviation in mains.
  • external alarm
  • Incorrect phase sequence
  • Protection by-pass contactor
  • limiting the number of starts
  • Incorrect command
  • underload
  • Overload
  • error of the external automation
