Product Description
30V 20A Small Water treatment automatic reverse high frequency switching power supply
Product Usage
Suitable for sewage treatment production line.
Features
Using the timing control function, the setting is simple and convenient, and the working time of positive and negative current polarities can be arbitrarily set according to the plating process requirements.
It has three working states of automatic cycle commutation, positive and negative, and reverse, and can automatically change the polarity of the output current.
The core components of the commutation are made of special superconducting materials, the control part adopts intelligent time control, the power is turned off during switching, and it has protection functions such as undervoltage, phase loss, overcurrent and short circuit.
According to customer needs, it can expand standard control interfaces such as 4-20mA, 0-10V, 0-5V, etc., and can also meet the requirements of RS485 communication interface with the host computer, RS232 and other control systems.

Switching power supply working principle:
The principle of voltage regulator switching power supply control regulator:
The switch knob repeatedly switches to a certain time interval. When the switch is turned on, the input power is supplied to the load through the switch knob and the filter circuit. During the entire switch is turned on, the power supply provides energy to the load;
When the switch is open, the input power is interrupted to provide energy. It can be seen that the input power supply that provides energy to the load is intermittent. In order for the load to obtain continuous energy power, the switching power supply must have an energy storage device. When the switch is turned on, part of the energy is stored in the switch. When it is turned off, The stored energy will be released to the load. The inductor is used for energy storage. When the switch is turned off, the energy in the energy storage inductor is released to the load through the diode to ensure that the load obtains continuous and stable energy. Because the diode allows the load to obtain continuous current, it is called a continuous current diode. This is how the switching power supply works.

How to install rectifier
This is installation way for remote control rectifier. Not only this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power supply/rectifier
4. We advice that all rectifiers should be isolated to increase of its life.
