MRM Series

MRM Series:Air-cooled model,Water-cooled model

  • Flexible output current capacity

    Increase output current by connecting power modules in parallel.

  • Universal input voltage

    It is possible to select either 200V – 240V or 380 – 480V, and use our equipment in every country.

  • Improved reliability

    • Reduces unexpected shutdown during operation by predetecting cooling fan failure.
    • Shields electronic circuits and major components from outside air.
  • Fits a wide variety of applications

    This is a versatile product thanks to CC/CV control mode.

  • Remote control and support of various communication devices

    Equipped with analog in/output and RS485 port as standard. Also supports open field network (option).

  • Various operating modes allow various output waveforms

    DC and Pulse mode are equipped as standard. The GOLD WAVE mode (Flexible waveform) is available as option.

    A. Chopper (pulse) mode

    • The pulse output can be set at a width of 10msec minimum.
      Suitable for precious metals plating and lead-free compatible parts.
    • Synchronized operation of multiple units available Option

    B. Single phase full wave mode

    Same functions as the DCAUTO HK-G series:

    • High speed communication
    • Supports open field network(Option)
    • Current integration function
    • Energization timer
    • Operation pattern memory
  • Integrated Ah meter function

    Effectively set integrated current value to manage your plating solution remote control optional.

In addition to the common features , the water-cooled model also has the following features.

  • Improved resistance to environment(power module)

    Enhanced shielding of the power module circuitry for stable and durable operation. The rectifier can be installed close to the plating tanks, thus reducing wiring length and power loss.

  • Boosted cooling performance

    When the rectifier is used as a single unit, it can withstand an ambient temperature up to 50℃.

  • Can use industrial water

    Our original water pipe system allows the use of both pure water and industrial water.
