Typical Applications
Electrolysis & Electroplating
Stable DC supply for electrolysis, electroplating and surface treatment; output voltage, current and control configured to the bath, electrodes and process curve.
Steel Cold Rolling & Surface Treatment
For stainless steel electrolytic pickling, electrolytic cleaning and degreasing, and tin/zinc plating lines — configured to line cycle, load and cooling conditions.
Industrial Heating & Monocrystal Furnaces
DC heating loads needing fast power regulation, including monocrystal furnaces and other industrial heaters.
Smelting, Pickling & Water Treatment
Continuous-duty industrial DC applications; selected by load capacity, control interfaces and protection requirements.
FAQ
What type of DC power supply is the DCA?
A water-cooled DC power module using IGBT high-frequency inversion — the building block of industrial DC supply systems.
Which industries use the DCA?
Electrolysis & electroplating, steel metallurgy, DC heating, monocrystal furnaces, non-ferrous metals, surface treatment and water treatment.
DCA vs. SCR DC supplies?
DCA uses IGBT high-frequency switching — smaller, lighter, faster dynamics. SCR suits different load and process boundaries. Choose by ripple, environment, maintenance and capacity.
Power per module?
Up to 60 kW. System capacity is set by output voltage, current, redundancy and site conditions.
Can modules be paralleled for more capacity?
Yes — the modular structure supports multi-module parallel configurations with room for later expansion.
Is N+1 redundancy supported?
Yes, per project. Whether and how much redundancy depends on continuous-duty requirements and maintenance strategy.
Which control modes are supported?
Constant current, constant voltage and constant power — the actual mode follows the process load and control requirements.
Can it connect to PLC or a host system?
Yes — analog, digital or communication interfaces connect to PLC, DCS or SCADA hosts per project.
Can it be used for hydrogen projects?
Yes for water electrolysis and similar DC supply; configure to electrolyzer voltage, current, start/stop mode, process curve and interlocks.
Which cold-rolling processes does it serve?
Stainless steel electrolytic pickling, electrolytic cleaning, electrolytic degreasing, tinning and galvanizing — confirmed against line equipment and load parameters.
How is cooling determined?
This is a water-cooled module; provide site water quality, temperature, pressure, piping and ambient temperature to confirm the cooling configuration.
What to provide for selection?
Output voltage, current, load type, duty cycle, control mode, communication, installation environment and cooling conditions; electrolysis projects also need the process curve and start/stop requirements.
