The PLS series is a low cost, phase sensitive control that provides an isolated contact closure when the proper A-B-C phase sequence is applied. It protects sensitive three-phase equipment and equipment operators from reverse rotation. This monitor is designed to be compatible with motor overloads or other three-phase equipment protection devices. Protection is ensured for equipment control centers where frequent reconnection or electrical code makes reverse rotation protection essential. Examples include mobile refrigerated containers, construction equipment, hoists, pumps, conveyors, elevators, and escalators.

工作原理

The internal relay and LED are energized when the phase sequence is correct. The output relay will not energize if the phases are reversed. Reset is automatic upon correction of the fault.

功能与特色

  • Continuous monitoring
  • Industry standard 8-pin octal plug connection
  • LED指示
  • Factory calibrated
