SR55s are ideal in applications requiring lower inrush currents and have a built-in internal bypass and patented iERS (intelligent Energy Recovery System) that reduces energy costs. The fully programmable units have a built-in touchscreen for application set up and monitoring and also feature integrated Modbus RTU with optional Modbus TCP or Ethernet/IP for communications as well as programmable analog and digital I/O for remote control. Starting at $975.00 with a two-year warranty, the SR55 series soft starters are UL listed, CE, REACH, and RoHS approved.
