water electrolysis IGBT power supply 12v 5000a with 4~20mA analog
interface
Electrolysis of water is the decomposition of water into oxygen and
hydrogen gas due to the passage of an electric current.
This technique can be used to make hydrogen gas, a main component
of hydrogen fuel, and breathable oxygen gas, or can mix the two
into oxyhydrogen, which is also usable as fuel, though more
volatile and dangerous

Features
Using timing control function, the setting is simple and
convenient, and the working time of positive and negative current
polarity 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.
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.
The superiority of periodic commutation pulse plating
1 Reverse pulse current improves the thickness distribution of the
coating, the thickness of the coating is uniform, and the leveling
is good.
2 The anode dissolution of the reverse pulse makes the
concentration of metal ions on the cathode surface rise quickly,
which is conducive to the use of a high pulse current density in
the subsequent cathode cycle, and the high pulse current density
makes the formation speed of the crystal nucleus faster than the
growth rate of the crystal, so The coating is dense and bright,
with low porosity.
3. The reverse pulse anode stripping greatly reduces the adhesion
of organic impurities (including brightener) in the coating, so the
coating has high purity and strong resistance to discoloration,
which is particularly prominent in silver cyanide plating.
4. The reverse pulse current oxidizes the hydrogen contained in the
coating, which can eliminate hydrogen embrittlement (such as the
reverse pulse can remove the co-deposited hydrogen during the
electrodeposition of palladium) or reduce the internal stress.
5. The periodic reverse pulse current keeps the surface of the
plated part in an active state all the time, so that a plating
layer with good bonding force can be obtained.
6. Reverse pulse is helpful to reduce the actual thickness of the
diffusion layer and improve the cathode current efficiency.
Therefore, proper pulse parameters will further accelerate the
deposition rate of the coating.
7 In the plating system that does not allow or a small amount of
additives, double pulse plating can obtain a fine, smooth, and
smooth coating.
As a result, the coating's performance indicators such as
temperature resistance, wear resistance, welding, toughness,
corrosion resistance, conductivity, resistance to discoloration,
and smoothness have increased exponentially, and it can greatly
save rare and precious metals (about 20%-50%) and save additives
(such as Bright silver cyanide plating is about 50%-80%)
