24V 200A alkaline water electrolysis power supply
Alkaline water electrolysis has a long history in chemical industry. It is an electrolyzer with two electrodes operating in a liquid alkaline electrolyte of potassium hydroxide (KOH) or sodium hydroxide (NaOH). These electrodes are separated by a diaphragm to separate the product gas and transfer the hydroxyl ion (OH -) from one electrode to the other. The comparison results show that the most advanced nickel based water electrolyzers with alkaline electrolytes are competitive and even more efficient than those using platinum group metal based electrocatalysts for membrane water electrolysis of acidic polymer electrolytes.
Electrolysis requires the presence of minerals in the solution. Tap water, well water and groundwater contain a variety of minerals, some of which are alkaline while others are acidic. Water with pH greater than 7.0 is considered alkaline; water below 7.0 is acidic. The requirement is that there must be ions in water to conduct electricity, so as to carry out water electrolysis process.

24V 200A alkaline water electrolysis power supply feature:
there are many important characteristics of a rectifier which makes them more suitable than a low-voltage generator for electroplating processes:
Rectifier saves energy; it adopts a high-frequency switching power supply transformer and as a result, the efficiency at which it converts current improves.
It is lightweight and also very small; if you have a thyristor rectifier, the size and weight will be 1/5-1/10. This weight and size make it very easy for you to expand, plan, install, maintain and move as the case may be.
Easy modulation; Rectifier output waveform can be modulated. Due to high frequency, the cost of output waveform adjusting processing is low and can be easily changed depending on what the users require. As a result, there will be room to improve the efficiency on site and also improve the quality of processing product.
Stability of output; the system has a high response speed, and as a result, the rectifier can adapt strongly to load changes and electricity network. This characteristic will ensure the accuracy of more than 1%. Also, the switching power supply works very efficiently to enable high precision control which will, in turn, improve the products quality.

Installation
| 1, Placing rectifier and keep the body stability; ensure good ventilation. |
| 2, Checking anodizing rectifier out cover if loosing. |
| 3, Connecting shell to ground to prevent static electricity. |
| 4, Conecting the AC input wire |
| 5, Connecting the DC output copper bars |
| 6, Connecting the rectifier remote control box,if local control ,skip this step |
| 7, Turn on air switch, then the fan starts to rotate and the power indicator light. |
| 8, Clockwise rotation adjustment button, voltmeter degree increases, working indicate light lighting. |
| 9, Adjust knob to maximum, then the voltmeter should indicate the rated voltage, current meter indicates the load volume accordingly. |
10, Disconnect the air switch, turn off the rectifier
