Summary
One point one Applicable scope
MDSP200 series Motor protection control (hereinafter referred to as the protector for the device) 660V Protection, monitoring and measurement of low voltage motor and motor starting and stopping control . The motor protector has perfect protection function, including: starting overtime, overload, short circuit, blocking, blocking, fault phase, three-phase current unbalance, under current and grounding, leakage, TE Time, over voltage, under voltage, external fault protection, to ensure the safety and reliability of motor operation. The motor protector has the function of monitoring operating parameters, real-time measurement of three-phase current, grounding current, leakage current, current unbalance, three-phase voltage, frequency and heat accumulation. The protector has Ten A failure record, record operating parameters of motor fault occurs, data is not lost power. Protection standard 4-20mA Transmission function, optional Modbus-RTU The communication function, can easily access Monitor System.
One point two Product features
( One Using) Thirty-two A microprocessor, fast calculation speed. Relay, power module and other components are imported industrial products, the hardware anti-jamming design, reliable performance. ( Two ) perfect protection function and event recording function, key electrical parameters measurement and monitoring function, fault recording and motor stop recording function. ( Three The thermal overload protection) with full memory function of the heat accumulation algorithm. This algorithm considers the influence of negative sequence current, and thermal overload protection algorithm is widely adopted, this algorithm is in strict accordance with the thermal model of motor is derived and verified by tests, thermal memory characteristics and foreign mainstream products are similar in applications where motor load or voltage change and frequent, full output is the motor can be guaranteed, and can cause the motor to obtain reliable protection. ( Four Using proprietary software) frequency synchronization algorithm, to ensure synchronization, strong anti-interference ability, thus greatly improving the anti-interference ability of electrical parameter measurement.
