Electrodialysis power supply

Features:

1. The company introduces international pulse width modulation technology specially designed for the characteristics of electrodialysis power supply: new upgraded line control technology, intelligent soft-switch synchronous rectification technology, energy saving 25%-28% than thyristor rectifier; and guaranteed to be full Load 365 days and 24 hours continuous operation, energy-saving structure and circuit design, small size, light weight, high efficiency, fully sealed, anti-corrosion, moisture-proof, waterproof, shockproof, anti-radiation, anti-interference.

2, networking costs: the use of digital networking technology, equipped with RS-485 communication interface, a set of twisted pair cable can be connected to all power equipment, can be directly connected to PLC or industrial computer, reduce a large number of analog output modules, light amount module, Power transmitter and cable;

3. The control system realizes the conversion of the communication protocol between the PLC and the power supply with the high-reliability 32-bit single-chip microcomputer, which completely solves the problem of the protocol mismatch between the PLC and the power supply. Because direct reading and writing of PLC memory, developers can focus on the development of the production line, only need to set the corresponding parameters in the corresponding memory unit of the PLC, greatly reducing the development pressure;

4. The control system can support HOSTLINK of Omron PLC, QNA of Mitsubishi PLC and RTU protocol of Siemens, and can also be customized according to PLC;

5, using advanced direct digital frequency synthesizer (DSP) waveform generation technology, the output frequency stability is high, continuity is good, measurement accuracy is high.

6, touch screen operation display, easy to operate, user-friendly, 7-inch color screen display, the parameters display at a glance.

Principle analysis: The electrodialysis power supply provides a DC electric field during electrodialysis of water or other substances. The selective permeability of the anion exchange membrane and the cation exchange membrane is utilized in the DC electric field, and a part of the ions are transported through the ion exchange membrane to another. Part of the water, so that part of the water is diluted and the other part of the water is concentrated to achieve water purification.
