GY900+ energy saving protection device for electric motor with the motor of the development of the national economy, wages rise goods prices, only the electricity energy is the best save cost, promote the production process indispensable motor strategy, but in the production process can not be such defects in the protection of the motor, GY900+ motor energy saving protection device is a basic function, motor protection energy consumption and power consumption, motor control part occupies an important position. GY900+ is almost penetrated into all areas of the industry, is an important guarantee for industry, agriculture, national defense and people's normal life, so it is very important to ensure the normal operation of the motor, and the motor caused by the use of saving electricity, reducing function is to maximize the use of. Motor waste burning and even lead to major safety incidents are common, so the loss caused by downtime is an immeasurable huge amount. Therefore, it is of great significance to do a good job of energy-saving protection of motor, which can save energy, improve production efficiency and economic efficiency and ensure safety in production.

A new generation of intelligent motor protection and control device in addition to the implementation of the conventional low-voltage motor protection control function, but also has the measurement, accident analysis, motor fault report and other functions, the system monitoring and protection control system as the integrated substation automation or power monitoring, improve the reliability and safety of the power supply system of enterprises. The utility model can improve the automation management level of the motor production and operation of the motor enterprise.

I. main features:

1. suitable for low voltage motors 380V, 660V, 1160V, rated current less than 1500A, rated frequency of 50Hz motor.

2. realize the remote automatic control of the motor, direct control of the field, panel LCD all Chinese instructions, signal alarm, field bus communication, and so on.

3., through the field bus, integrated industrial MODBUS-RTU communication protocol, and through intelligent MOTOR control center communication, to achieve the motor loop remote measurement and control, protection, settings.

4. products of small volume, compact structure, convenient installation, low voltage control cabinet in the terminal and 1/4 1/4 and the other drawers can be installed directly, improve the reliability and safety of the control loop and the level of automation management.

5. accuracy: measuring voltage, current, power, accuracy of 0.1%.

6. work power supply: enhance the power supply working range, high anti-interference ability
