FlexKraft 2 is a modular, switch-mode DC rectifier for electrochemical processes, built from identical power modules controlled over a digital CAN bus. It delivers up to 100 kW per stack with approximately 92% efficiency and about 1% output ripple. One generation, three variants: FlexKraft 2 for standard surface finishing, FlexKraft 2A (released Q1 2027) with an integrated Active Front End for demanding grids, and FlexKraft 2X (released Q1 2027) with an extended voltage range up to 600 V and up to 95% efficiency.

FlexKraft 2 supplies DC power for electroplating and other electrochemical processes, from decorative and functional plating to anodizing and other surface finishing. The standard variant covers typical plating lines; FlexKraft 2X extends the platform to high-voltage and high-power electrochemical applications. Because each half-module can be controlled on its own, the same rectifier serves one large bath or several smaller tanks.

One FlexKraft 2 stack delivers up to 100 kW, 40% more than the previous FlexKraft generation in the same footprint. Each half power module supplies 334–400 A; output voltage reaches 150 V, or 600 V with FlexKraft 2X (released Q1 2027). Input is 380–480 VAC ±10%, and air- and water-cooled versions are available.

A FlexKraft 2 rectifier is built from identical, standardized power modules that stack into units of up to 100 kW stacks. You size the configuration to today's demand and add modules as it grows, without redesigning the system. One module type fits every FlexKraft 2 size, so you stock one spare part for the whole range.

If one power module faults, FlexKraft 2 keeps running on the remaining modules at reduced output, so production continues instead of stopping. Module-level monitoring shows which module is affected. One person exchanges a module in under 15 minutes, with no specialist tools, and the rectifier returns to full output.

Yes. One FlexKraft 2 stack supports up to 20 independently regulated outputs. Half-module outputs are grouped to match your line layout, and each output has its own current or voltage setpoint. Along one longer bath, you can distribute current by zone, for example 20 / 70 / 100%, to control the deposit and avoid the dog-bone effect.

FlexKraft 2 uses digital control on a CAN bus backbone, with one control and power supply interface for up to 10 stacks. Each half-module is addressed, measured and controlled individually over that bus. Analog and digital interface options connect the rectifier to your PLC or line supervision, and faults are reported per module.

FlexKraft 2 keeps the assembly structure, power module dimensions and 380–480 VAC input range of the previous FlexKraft generation, so it fits into an existing FlexKraft installation. For older thyristor rectifiers, it is a modernization path that brings lower ripple, higher efficiency and module-level redundancy to the same line; our engineers review the existing busbars, cooling and control interfaces with you before an exchange.

FlexKraft 2 uses next-generation SiC semiconductors in its switch-mode power stage, which is what lifts conversion efficiency to approximately 92% and to 95% in FlexKraft 2X (released Q1 2027). SiC devices switch with lower losses than conventional silicon, so less energy turns into heat inside the rectifier. That means lower electricity consumption per plated part and a smaller cooling burden in the rectifier room.

A modular switch-mode rectifier such as FlexKraft 2 regulates its output many thousand times per second, while a thyristor rectifier switches at mains frequency. The practical differences for a plating line: about 1% ripple without large output filters, faster and more accurate current and voltage control, higher efficiency, a smaller footprint per kW, and redundancy at module level. A thyristor unit is one large block; if it fails, the output is gone.

FlexKraft 2 delivers approximately 92% efficiency; FlexKraft 2X (released in Q1 2027) reaches 95%. At 100 kW DC output, that cuts conversion losses from 11.1 kW for a 90% rectifier to 8.7 kW (−22%) with FlexKraft 2 and 5.3 kW (−53%) with FlexKraft 2X, every operating hour. Lower losses also mean less heat to remove, so cooling runs smaller or less often. Lower kWh per unit of output lowers CO₂ intensity, which supports energy and ESG targets.

FlexKraft 2 delivers about 1% output ripple with 0.1 A / 0.01 V setting resolution, in constant-current or constant-voltage mode per output. Ripple is the AC component left on the DC output; too much of it causes burning, rough deposits and uneven thickness. Low ripple and accurate control give repeatable deposits batch to batch, which you can measure as process capability (Cpk).

FlexKraft 2A and optional FlexKraft 2X (both released Q1 2027) have an integrated Active Front End that keeps total harmonic distortion below 5% at the grid connection. The AFE draws a near-sinusoidal input current and stabilizes the rectifier during voltage sags and transients, so you avoid external harmonic filters, power factor correction and oversized transformers. On a stable grid the effect is smaller, but input stays cleaner and output more consistent.

FlexKraft 2 needs one spare power module type for the whole range, exchanged by one person in under 15 minutes. Fan speed is temperature-driven at module level, so fans run slower at partial load; that lowers noise and fan wear and extends service intervals. Module-level monitoring tells your team which module has a fault, so troubleshooting starts at the right place.

FlexKraft 2 offers polarity reverse as an option, a polarity switch for processes that need periodic reversal. Programmable ramps and pulses are available within the rectifier's current and voltage control. For programmable periodic pulse reverse and phase-shifted pulsing, KraftPowercon offers the ModuPulse line, which is a separate product.
