18V 3500A Decorative Chrome Plating Rectifier is a custom industrial DC power supply for decorative chrome plating. It provides the adjustable DC current used during decorative chromium deposition. It helps the line establish a controlled electrical operating point for the specified plating procedure. The final configuration is matched to the actual process load, production duty, and site conditions.
How to confirm voltage and current
The published 18V / 3500A / 63 kW rating is a reference DC envelope, not a default process setpoint. Size current from the exposed work area, required current density, rack loading, and the maximum number of parts in the tank. Confirm voltage from the live tank reading, geometry, contact resistance, busbar path, and cable losses.
Reference electrical envelope
| Selection item | Reference for this page |
|---|---|
| Published DC output | 18V, 3500A (63 kW) |
| AC input direction | AC 380V or AC 415V, selected against the site supply |
| Main control mode | Constant-current or constant-voltage, selected for the process |
| Final confirmation | Load, duty, cooling, controls, interfaces, and installation conditions |
Avoid selecting only by nameplate
The output rating tells the buyer the available DC ceiling. It does not state that every installation runs at maximum current or voltage. A lower normal operating point can be appropriate when the active area, cell count, work loading, or line speed is lower; a larger rating is reviewed when the maximum condition, expansion plan, or connection losses require it.
Buyer data for a project review
For a useful quotation, share part geometry, exposed area, bath process, target current density, load quantity, and maximum tank voltage. A photograph of the existing unit, a load trend, or a measured operating voltage is often more useful than selecting only by a previous nameplate.
Common selection questions
Is 18V always the required process voltage?
No. The required voltage is established from the actual loaded process, including cells or tank voltage and connection losses. The published value is the available reference ceiling for this configuration.
Can the current be changed from 3500A?
Yes, the final current direction is reviewed from the real active area, current-density target, cell arrangement, production loading, and expansion requirement.
Practical planning note
Installation planning deserves the same attention as the output rating. Ask where the unit will be positioned, how air or water cooling is available, where cables enter, how maintenance access is handled, and whether the site has unusual ambient conditions. These inputs make the enclosure and connection discussion more useful before a final configuration is confirmed. For this 18V 3500A reference, the relevant question is how the decorative chrome plating load behaves at the intended maximum condition.
