MM300 Motor Management System biased to reflect the additional rotor heating. A programmable K factor setting allows the amount of derating to be adjusted. The MM300 is a digital motor protection and control system, designed for Low Voltage motor applications. Flexible and powerful, the MM300’s protection can be scaled to the specific requirements of your system. Hot / Cold Safe Stall Ratio This ratio defines the steady state level of thermal capacity used (TCU) by the motor. This level corresponds to normal operating temperature of a fully loaded motor and will be adjusted proportionally...
