Characteristics of aluminum anodized dc rectifier:
Aluminum anodic oxidation DC rectifier is used for anodizing
aluminum. This process is actually the process of forming aluminum
oxide film from aluminum profile or aluminum alloy profile by
electrolytic aluminum surface. Our rectifiers also include
imitation gold electroplating power supply, pulse electroplating
rectifier, high-frequency electroplating power supply,
A. Digital timing system;
B. Ampere hour meter;
C. Standard interface;
D. Control signal interface.
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.
Other advantages
1. Cabinet
a: Adopting completely digitalized machining
b: Adopting cold rolled production of iron steel sheet, after phosphorization, zinc plating, plastic spray, the rectifier gets better structural
strength and anti-corrosion.
c: Reasonable structure design, isolated inverter design,
rectification part is convenient to disassemble and mend because of
its neat assembling.
d: Radiator gets better cooling effect because of its 1.5 times capacity.
2 Electric control system
a: The rectifier adopts full bridge phase-shifted soft switch
control, ensuring the lowest power loss of IGBT. The capacity of
IGBT become 3 times bigger.
b: The main transformer. It adopts amorphous core to increase transformer efficiency and cool transformer, and not only can lighten rectifier weight,
but also can strengthen rectifier stability and reliability. At its
elementary stage, it adopts series blocking capacitor.
c: Magnetic deviation automatic correction circuit is adopted and
the total power of magnetic core gets enlarged 1.5 times.
3 Schottky Barrier Diode
a: It has been expanded 4 times.
4 All the controlling boards get antiseptic treatment with imported
lacquer.
Anodizing introduction；
Anodizing is an electrolytic passivation process that is used to
increase the thickness of the natural oxide layer on the surface of
metal parts. Aluminium alloys are anodized to increase corrosion
resistance and surface hardness, as well as to allow dyeing
(colouring), improved lubrication, or improved adhesion. Different
anodizing processes include hard anodizing, chromic acid anodizing
(CAA), sulphuric acid anodizing (SAA), boric sulphuric acid
anodizing (BSAA), tartaric sulphuric acid anodizing (TSAA) and
phosphoric acid anodizing (PAA)
