Water-cooled electroplating power supply FlexKraft - the modular SMPS high-current power supply for electro-chemical processes with demanding operating environments.

Secure the reliability of your electrochemical process with water cooled FlexKraft high-current power supplies

Five reasons for choosing FlexKraft water-cooled power supplies:

      1. Your plating environment is too hot for air cooling (40°C or more)
      2. You don’t want to invest in a controlled cooling environment for your power supplies
      3. Conditions are too dusty or harsh for effective air cooling
      4. You want to reduce thermal stress to optimise rectifier life and performance
      5. You use corrosive alkaline solutions, or powder bases that generate particulates

PLUS: Our water-cooled FlexKraft™ power supply is covered by an extended 3-year guarantee, as part of our special promotion running until December 2024.

Simply use your own liquid-cooling system, or add our purpose-built CoolKraft™ heat exchanger if you prefer.

FlexKraft high-current power supply

Dual output

  • The possibility to have one power supply working as two, saves space and up to 15% of the investment cost

Control system

  • The power supply can be run in both CV and CC-mode without limitations, with possibility to set both voltage and current separately. This provides total control of the electroplating process – of highest value when requiring voltage limitation at controlled current.

Operating conditions

  • FlexKraft can operate continuously at maximum output for longer periods in ambient temperature of up to 50°C.

The table below displays possible current and voltage values, along with corresponding power supply dimensions.

With FlexKraft – liquid cooled electroplating rectifier, you can secure the reliability of your production process, while optimizing costs.

Here are the key enabling functions:

Standardization and modular design

  • facilitate redundancy. If a module would fail, operation can be continued with less output
  • It takes less than 15 min to exchange a faulty power module, reducing standstill.
  • allow for an optimized configuration, saving space and upgrading the power size when needed.
  • with one critical spare part /power module fitting to the entire range of the power supply regardless size and manufacturing year, service/repair are straightforward
  • enable spares optimization, reducing inventory needs and costs.
