Compare plating rectifiers
Kraft Powercon alternative: compare rectifiers by what matters after installation
Kraft Powercon builds respected switch-mode rectifiers, made in Sweden. Their sealed water-cooled line can sit near the tanks, but their air-cooled units pull shop air through the electronics and are best kept in a clean room. ION Rectifiers gives you IP65 corrosion-proof protection across both air and water-cooled units, so the rectifier sits right at your line, American-made and serviced on-site. If you are weighing a Kraft Powercon alternative, compare plating rectifiers side by side on what actually affects a finishing shop after installation. You can also review our Dynapower alternative for plating rectifiers.
Compare what matters on a finishing floor
Amps and volts are the starting point. For a plating or anodizing shop, the fit is decided by where the unit can live, how it is serviced, how easily operators run it, and how it controls ripple.
| Buying criterion | ION Rectifiers | Kraft Powercon |
|---|---|---|
| Focus | Plating and anodizing, purpose-built | General surface finishing and high-current power, global |
| Ease of use | Intuitive 7-inch touchscreen with recipes and thickness programs, not a button-only panel where functions hide under many clicks | Digital controls; confirm operator workflow |
| Ripple control | True low ripple from a properly sized internal inductor and capacitor | Switch-mode; confirm filter sizing |
| Enclosure rating | IP65, molded fiberglass or polycarbonate (NEMA 4, 4X, 12, 13) | IP44 water-cooled (sealed); IP32 air-cooled |
| At the line | Air and water units are both built to sit at the tank | Sealed water-cooled can sit near the tanks; air-cooled (IP32) best in a clean room or away from tanks |
| Cooling | Air-cooled to 250 A (IP65) or water-cooled above | Air-cooled (IP32) or water-cooled (IP44) |
| Serviceability | On-site repair, plug-and-play, direct US support | Global network; parts and repairs from abroad |
| Manufacturing | American-made, built for finishing shops | Made in Sweden (production in Sweden, China, India) |
| High-speed pulse | Available when your process needs it | Switch-mode focus; confirm pulse options |
| Output range | To 5,000 A at 12 V, or 1,000 A at 50 V | Broad switch-mode range; confirm per model |
Where each supplier fits
A fair read: Kraft Powercon is a strong choice if you want a large, globally established switch-mode brand. ION is the Kraft Powercon alternative to weigh when you want IP65 corrosion-proof protection at the line for any cooling type, easy operation, and service from within the United States.
- You want a large, long-established global switch-mode brand across many industries.
- You are choosing the sealed water-cooled (IP44) line, which can sit near the tanks, and a clean space for air-cooled units is acceptable.
- Overseas manufacturing and parts logistics are acceptable for your service timeline.
- You want IP65 corrosion-proof protection across both air and water-cooled units, so even an air-cooled rectifier sits right at the tank.
- You want American-made parts and on-site service, not repairs and parts shipped from abroad.
- You want an intuitive touchscreen operators actually like, not a button-only panel where common functions hide under many clicks.
- You want true low ripple from properly sized internal filtering, where many rectifiers undersize the filter or lean on the plating bath.
- You want high-speed pulse available for when your process is ready for it.
The hidden cost of a rectifier that can't sit at the line
An air-cooled rectifier that pulls shop air through its electronics cannot live in acid mist. It belongs in a clean, ventilated power room, or far enough from the tanks to stay clean. That distance is not free. It shows up in construction, copper, energy, and floor space, every year the line runs.
Long runs from a power room to the tanks mean more copper, larger conductors, and voltage drop that shows up on your electric bill.
An air-cooled unit that pulls shop air through its electronics needs its own ventilated or controlled space, taking floor area and adding cost.
Voltage drop over long runs becomes wasted heat, and the room needs its own cooling. A rectifier at the tank avoids both.
Put the rectifier where the work is
ION enclosures are IP65 corrosion-proof, molded fiberglass or polycarbonate, for both air-cooled and water-cooled units. Even an air-cooled ION rectifier is built to sit at or beside the tank. Short bus runs, no clean room, and a simpler install. The unit is made for the finishing floor, not protected from it.
Parts and service without the ocean in between
Kraft Powercon manufactures in Sweden, China, and India. When a line is down, parts and factory support come from overseas, and that distance can become downtime. ION rectifiers are engineered, built, and serviced in the United States, with most repairs handled on-site and direct support from the people who build them.
Why ION is a strong Kraft Powercon alternative
Built for the finishing floor, easy to run, and supported close to home. Here is what that looks like in the unit itself.
An ION 1000 A / 50 V rectifier with the 7-inch HMI touchscreen. Built in the United States for plating and anodizing lines: air-cooled to 250 A, water-cooled up to 5,000 A at 12 V in a single enclosure.
- IP65 at the line
- US parts & service
- Intuitive HMI
- ≤2% ripple
Corrosion-proof molded enclosure, air or water-cooled, sits at or beside the tank. Higher protection than IP44 or IP32.
Engineered, built, and repaired in the United States, with parts and support that do not ship from overseas.
Recipes, amp-hour counters, and thickness programs on a 7-inch screen. No button-only menus buried twenty clicks deep.
A properly sized internal inductor and capacitor, where many rectifiers undersize the filter or lean on the plating bath.
Sized for plating and anodizing, 0 to 50 V, air-cooled to 250 A or water-cooled above.
High-speed pulse capability is available for the processes that benefit from it.
An intuitive touchscreen, not a button maze
ION runs on a 7-inch touchscreen built for the shop floor. Operators start, save, and repeat a process right from the screen, without digging through button-only menus twenty clicks deep. The depth is still there for engineers who want it: recipes, amp-hour counters, thickness programs, and full waveform control.
Clean power that does not depend on your tank
Every rectifier turns AC into DC, and that DC is never perfectly smooth on its own. Many rectifiers undersize their filters, or lean on your plating bath to smooth the output, which ties finish quality to tank conditions you cannot fully control. ION filters the power inside the unit, with a properly sized inductor and capacitor, so the current reaching your parts stays clean and consistent.

Buyer watch-outs
Run these checks on either supplier before you buy. They surface the differences a nameplate rating hides.
Is the enclosure sealed against acid mist (IP rating), or does it pull shop air through the electronics?
Can the unit sit at your line, or does an air-cooled model need a clean room and long bus-bar runs?
Where do parts and repairs come from, and what is the lead time when a line is down?
Can operators run and repeat a process without digging through a button-only menu?
Is ripple filtered inside the unit with properly sized components?
Is the supplier focused on plating and anodizing, or is finishing one of many markets?
Kraft Powercon alternative: your questions answered
Straight answers to the questions shops ask when they weigh Kraft Powercon against ION.
Where are Kraft Powercon rectifiers made?
Kraft Powercon is a Swedish company that manufactures in Sweden, China, and India. ION rectifiers are engineered and built in the United States specifically for plating and anodizing shops, with parts and service from within the country.
Can a Kraft Powercon rectifier sit at the plating line?
Kraft's sealed water-cooled FlexKraft (IP44) can be placed near the tanks. Its air-cooled units (IP32) pull ambient shop air through the electronics, so they are best kept in a clean power room or away from the tanks. ION's IP65 enclosure, air or water-cooled, is built to sit right at the line.
How does ION control ripple?
ION filters the DC inside the unit with a properly sized inductor and capacitor. Many rectifiers undersize their filters, or lean on the plating bath to smooth the output, which ties finish quality to tank conditions you cannot fully control. ION keeps the current reaching your parts clean and consistent.
Is an ION rectifier easy for operators to run?
Yes. Operators run it from an intuitive 7-inch touchscreen with saved recipes, amp-hour counters, and thickness programs, not a button-only system where common functions are buried twenty clicks deep. Engineers still get deep programmability underneath.
Does ION offer pulse plating?
Yes. ION offers deep, programmable high-speed pulse for shops that need it. A shop does not need pulse to benefit from ION's IP65 at-line design, US-based service, and easy operation, so pulse is there when your process is ready for it.
