The "Modular DC Power Supply for Surface Treatment 'MRM Series'" that provides the necessary current by combining modules has added a "Water-Cooled Model." It retains the basic functions of the conventional "Air-Cooled Model" while enhancing various features and performance. Improved Environmental Resistance - Achieves a structure that is less affected by the surrounding environment compared to the air-cooled model, maintaining stable characteristics over the long term. - Allows for placement near the plating tank, contributing to the minimization of output wiring and reduction of power loss. Enhanced Cooling Performance - Supports usage in environments with ambient temperatures of up to 50°C (when using the power module alone). Use of Industrial Water is Possible - The internal piping employs our unique water pipes, allowing the use of not only pure water but also industrial water. Others - Compatible with worldwide input voltages - Supports rated input voltages of 200V-240V / 380V-480V. - Supports various output currents and output waveforms - Can accommodate up to 4000A with parallel connection (expansion) of power modules. - Standard single-phase full-wave and pulse output available. - Standard equipped with analog input/output and RS-485 communication.
