Product Description WDS308 Integrated dust monitoring sensor is a specialized small instrument applied to monitor dust at construction sites. It can monitor eight meteorological elements, wind speed, wind direction, air temperature, air humidity, air pressure, rainfall, radiation, UV index, and can also monitor three environmental factors, PM2.5, PM10 and noise. The system is modularized and can be configured flexibly. Small volume, low cost, and it suitable for industrialized intensive stationing monitoring. Features l Maintenance free design l Standard output protocol RS485 l Small volume, light weight l Installation height is unrestricted l Low power consumption, high precision l Integrated dust monitoring system l China's first production company
Rectifier R50030G1 is a high efficiency and high power density 15kW AC DC rectifier. It supports 3 phases 260Vac 456Vac input voltage and 500Vdc nominal output. It is built in an isolated CAN bus port to communicate with the control unit using CAN protocol. The output can be adjusted through the control unit. Features including soft start, input output protection, low noise, and parallelable
Product description Transformer Standard current transformer are also called precision current transformers, current transformer standards, standard CT and current transformer standards. Transformer standards are divided into current transformer standards and voltage transformer standards. Standard current transformers are used in the error test of transformers. Used as a current transformer calibration standard technical parameter Temperature -5 40 Relative humidity 80% Rated Primary Current 5-5000A 5A,1A Rated secondary current 5A 1A Accuracy Class 0.05S Allow long-term work under the rated current; More than120A across the core. Precautions The current of standard CT and tested CT must be the same in CT calibration. Follow the given wiring diagram strictly. Test whether the load box is accurate or not before calibrating the transformer. Forbid secondary winding opening during the calibration. Select demagnetization before calibration.The wiring diagram is shown in figure 5. Short out the secondary winding before cutting off the power when the demagnetization is finished. Principle wiring diagram of CT with large current generator is similar to above diagram. They are the same except the output winding of large current generator and primary winding of transformer are the same one.
