Product catalog summary
Overview: The Motortronics MVC4 is a medium voltage soft starter designed for AC induction or synchronous motors, offering advanced motor protection and smooth starting capabilities. It supports voltages from 1kV to 15kV and can handle up to 20,000 HP.
Specifications: The MVC4 supports 3-phase medium voltage AC motors with supply voltages ranging from 1000V to 15kV. It offers overload ratings of 600% for 30 seconds and 500% for 60 seconds. The power circuits use series strings of SCR power modules, and the system includes transient voltage protection with dv/dt circuits.
Motor Protection: The MVC4 monitors excessive thermal conditions and adjusts for phase current imbalances. It retains thermal memory without batteries and adjusts the thermal model based on motor temperature and power loss. It includes features like electronic overload, phase loss, and short circuit detection.
Starting Methods: The MVC4 offers Closed Loop Torque (CLT™) using PID algorithms, voltage ramp with current limit, and dual ramps for different load conditions. It also supports jog functions for initial machine setup and low-speed load positioning.
Integration and Communication: The MVC4 features flexible I/O with programmable relay outputs and analog outputs. It supports communication via RS-232, RS-485, and optional modules for Probus, DeviceNet, EtherNet/IP, PROFINET, and Modbus TCP.
Advantages: The MVC4 provides smoother starting than traditional methods, better adaptability, and lower operating costs compared to VFDs. It does not require phase-shifting transformers or additional cooling, resulting in better efficiency and reliability.
Enclosure and Environmental Conditions: The MVC4 is housed in a NEMA 12/IP54 enclosure for indoor use, with options for NEMA 4/IP65 weatherproof units for outdoor environments. It operates in ambient temperatures from 0 to 50°C and supports altitudes up to 1000m without derating.
Additional Features: The system includes a digital control unit with a programmable keypad and LCD display, differential protection, and statistical data logging for up to 60 events. It also offers metering capabilities for voltage, current, power factor, and more.
