General Purpose Rectifier
Modular water-cooled model

The MRM series of power modules is expanding with a water-cooledmodel. Outputs up to 4000A while maintaining the basic functionsof the air-cooled modelApplications▶ Plating▶ Electrolysis▶ Battery Charger▶ Power supply for Electrical Discharge Machining
Remote control(option)

Power module(water-cooled model：Output15V/500A）

Control module without operation panel is also available.

Water-cooled model features■ Improved resistance to environment(power module)
Enhanced shielding of the power module circuitry for stableand 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 waterand industrial water.

Same features as our conventional rectifier■ Universal input voltage■ Wide variety of applications

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

■ Various output currents and waveforms
Connect several power modules in parallel for a maximum
ouptut of 4000A. DC and Pulse modes are equipped as
standard and support many applications such as plating on
precious metals.The GOLDWAVE mode (Flexible waveform)
allow you to create your own waveform (option).

The control of constant voltage and constant current makes it aversatile product suitable for a wide array of usage.

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

■ Integrated ammeter function
Effectively set integrated current value to manage your platingsolution either on the control module or via remote control (option).
* Feel free to ask our sales staff for any details, including the installation environment.
