The integrated motor protection controller adopts the latest DSP digital operation core and 24 bit high-precision AD sampling, which has advantages such as strong anti-interference ability, high sampling accuracy, accurate alarm/fault diagnosis, stable and reliable operation, compact size, Chinese menu, easy operation, and networking. It has various protection functions, self starting function when shaking electricity, and direct starting control function required for general AC motors. During normal operation, the LCD Chinese LCD screen clearly and intuitively indicates the operating status, working current and voltage of the motor; After an alarm or fault protection action, the display interface automatically lights up the backlight and displays alarm/fault information, making it convenient for on-site maintenance personnel to find the cause of the accident and quickly inspect and repair the equipment. The product has an RS485 remote communication interface and a DC 4-20mA analog output, which facilitates the formation of a network system with PCL, DCS, and other components to achieve remote monitoring of motor operation.
characterization
The shell is made of 100% pure PC+ABS engineering plastic, with strong weather resistance;
Face frame size 96 × 48mm, with high installation density on the disk surface, suitable for various drawer cabinets;
LCD high-definition Chinese LCD display screen, wider viewing angle, more intuitive display, and more convenient button operation;
It has protection functions such as locked rotor, startup timeout, overload, overcurrent, underload, phase loss, zero sequence (leakage), tE time, overvoltage, undervoltage, etc. The protection setting and time are set separately;
The unique "anti shaking" function, namely the self starting function of shaking electricity, is suitable for equipment with high requirements for continuous operation, and automatically restarts according to the set time after a short power outage;
When not purely protected, it has a direct start control function, and can choose between pulse control start and level control start;
The measurement accuracy of current and voltage is level 1, with a range that covers the starting current range of the motor and good linearity;
The protection level of the motor is level 5, which meets the national relay protection requirements, and the protection operates reliably, without misoperation or rejection;
The zero sequence (leakage) current sampling three-phase current vector algorithm eliminates the need for external zero sequence current transformers for ground fault detection;
It integrates multiple functions, including ammeter, voltmeter, thermal relay and time relay;
The analog output of DC 4-20mA can be set to correspond to the three-phase current, zero sequence current, and three-phase line voltage of the motor;
Equipped with RS485 communication interface and sampling standard Modbus-RTU slave protocol, it is convenient for networking with automatic control systems.
