The 12V 300A high-frequency electroplating rectifier is a DC power
supply device specially designed for precision electroplating,
laboratory research and development, and small-scale industrial
production. It adopts 220V single-phase AC input, is compatible
with the standard mains power, and has an output of 0-12V/0-300A
that is continuously adjustable, ensuring that the electroplated
layer is uniform and dense. It is suitable for high-precision
processes such as gold plating, silver plating, and copper filling
in PCB through-holes.
Core Features
High Efficiency and Energy Saving
It adopts high-frequency IGBT technology with a conversion
efficiency of ≥90%, which is more than 15% more energy-efficient
than traditional silicon rectifiers.
It has an ultra-low ripple (≤1%) to avoid rough or nodular plating
layers and improve the surface finish.
Intelligent Control
It has local touch screen control + RS485 remote communication,
supports PLC automation integration, and is suitable for
intelligent production lines.
The single-chip microcomputer enables precise adjustment with a
voltage/current accuracy of ±0.5%.
Industrial-Grade Reliability
It has a forced air-cooling system (with IP21 protection),
intelligent temperature-controlled speed regulation, and can
support full-load operation in an environment of 40°C.
It has multiple protections: overvoltage (OVP), overcurrent (OCP),
short circuit (SCP), and overheating (OTP) protections are all
available.
