plasma differential of arc oxidation power supply

Description features:Main technical characteristics:
1. Using digital GAL gate array one chip microcomputer and Siemens PLC and touch
screen operation, computer control technology, with a high degree of automation
and reliable and strong anti-interference capability, easy operation and maintenance.2. Various output characteristics: DC output, unipolar pulse output, bipolar pulse
output and so on.
3. Various running modes, fine parameter setting, precise control, wide regulating
range.
4. Arbitrary setting various technical parameters, such as current, voltage, time
and waveform combinations. With online programmable functions, intelligent technical
curve database, and unipolar and bipolar characteristics which can choose
arbitrarily.
5. With characteristics of high-frequency switching power supply, and auxiliary electromagnetic
field facilities, converting frequency is higher than 95%.
6. Using mature technical parameters to construct online database, therefore to set
up intelligent expert system. It seems engineers are on-line; the process is
auxiliary controlled by PLC.
7. Time can choice from 0 to 999 hours, and the precision can be correct to minute
even second.
8. With constant current, constant voltage, constant power output ways. Especially
in the constant power output, the simulated energy level field principles make
it can achieve the effect: large processing surface areas, small current, obvious
energy-saving.
9. The number of positive and negative pulse can be arbitrary assemble and separate
set, which can make the processing to achieve the best effect, setting scope
is 1 to 999.
10. The dead band time of positive and negative pulse can be adjusted, and the shortest
time is 80ns.
11. The width of positive and negative pulse can be separately adjusted; the occupied
space rate can be set between 5% and 95%. The inverting frequency range is
10Hz to 2000Hz.
12. Multi-parameter monitoring function, self-diagnosis fault function and protection
function.
13. The PLC Touch screen dynamically displays tank liquor temperature, current, voltage,
and time. With over-flow, over-voltage, phase-missing, over-temperature
alarm and other electronic circuit's automatic protection function.
14. Current and voltage stability accuracy less than ¡À 1%
15. With the function of Storage and recording technology curve at all times, according
to technology curve, we can analyze and optimize the process parameters.,
thereby making products to satisfy the best technology requirements, and improving
product's quality and yield.
16. According to Users needs, it can configure RS-485, 232 and PRESS BUS computer
communication interfaces to make computer group control functions, monitor and
control functions come true.The main technical data
