Protection control system MPS series

digitalmotor

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. Operator Interface (MPS-OPI) • Large, bright, 4 x 20 vacuum-fluorescent display • Display metered values • Access set points • Powered by Control Unit • Panel mount or attach directly to Control Unit • Remote mounting (1.2 km or 4000 ft maximum loop length) • 1/2 DIN size • Hazardous-location certified Control Unit (MPS-CTU) • Current inputs—5-A or 1-A secondary phase current transformers • Voltage inputs—up to 600 V without PTs • Earth-leakage input—5-A or 1-A secondary or sensitive transformer • Tachometer (high-speed pulse) input • 8 digital inputs, 5 relay outputs, 1 analog input and output
