MPS Series - Motor Protection System

Product Status| Activei

The MPS series Motor Protection System offers comprehensive voltage protection and starter control for medium voltage motors. The system monitors voltage, current, and temperature to provide a comprehensive package of protective functions. The MPS is a modular system with integrated protection, motor control, metering, and data-logging functions. This system is typically used to provide protection for three-phase low- and medium-voltage, medium to high-horsepower induction motors.

Operation
The Control Unit (MPS-CTU) is the core module. It can operate as a standalone unit or with the Operator Interface (MPS-OPI), RTD Modules (MPS-RTD), and Differential Module (MPS-DIF). The CTU can be programmed using the OPI or the communications network. Programmable inputs and outputs provide a flexible hardware platform and custom software can be easily loaded from a PC to the CTU’s flash memory.
