PSR model softstarters easily communicate with factorywide networks and other equipment.Available in a range of 3-to-45 A, these devices include the ABB FieldBusPlug communication system.
The softstarters are communication protocol-neutral. Thus, the units can be ordered with a neutral fieldbus adapter so that they are ready to communicate with DeviceNet, Profibus DP or Modbus RTU. To avoid the excess cost of built-in, universal-translator hardware, an accessory FieldBusPlug is simply plugged in — and the PSR can instantly communicate with these protocols.”
The wide operating voltage range of the softstarter family reduces back-up inventory requirements. Three sizes are available with widths ranging from 1.77 to 2.13 inches (45 to 54 mm), covers rated currents from 3 to 45A, up to 600 Vac, and for control voltages of 24 Vdc or 100 to 240 Vac.All sizes include a “Run” signal, while sizes from 25 to 45 A add a signal relay for “TOR” or full voltage. These can be attached to an automation control system for closedloop control or operator indication.
The softstarters have integrated by-pass, and cooling fans can be attached to increase the starting capacity. Standard starts without the fan are 10 per hour; with the fan, 20 starts per hour are possible.
A softstarter ensures the smooth starting and stopping of ac motors by reducing the effective voltage. The compact PSR Softstarter is an alternative for motor starting. When selected over other approaches, it provides control feedback, consistent acceleration, and improved drive component reliability. The units have been tested and approved for UL and CCC, includes the CE logo and meets the directives of RoHS.
