Custom Electrolysis Power Supplies & Rectifiers for OEMs
Designing a highly efficient titanium electrode stack is only half the engineering equation for water treatment brands. Driving that cell with stable, clean, and reliable direct current determines the actual lifespan of your product in the field. Century operates as a dedicated contract manufacturer, delivering scalable, fully customized OEM electrolysis power supply solutions for global water treatment brands.
Whether your R&D team is launching a new line of consumer-grade salt chlorinators and needs high-volume power centers, or you are an industrial skid builder requiring massive DC outputs for chlor-alkali production, we provide complete vertical integration. As a true factory partner, we engineer and manufacture every DC power supply for electrolytic cell applications entirely in-house—from bare-board logic design to the final NEMA-rated enclosure assembly. Bring us your electrical schematics, or let our engineers design a system around your specific cell dynamics.

Complete Contract Manufacturing: From PCBA to Firmware
We do not simply assemble off-the-shelf electrical components. Century functions as a comprehensive Electronic Manufacturing Services (EMS) provider tailored specifically for the harsh environments of electrochlorination.
- Printed Circuit Board (PCB) Assembly: The heart of any reliable power unit is its logic board. We maintain dedicated SMT (Surface-Mount Technology) lines for in-house printed circuit board (PCB) assembly. This gives us total control over the Bill of Materials (BOM), ensuring that only premium, high-temperature-rated capacitors, IGBTs, and microprocessors are populated on your boards.
- Firmware & UI/UX Development: A power supply must integrate seamlessly with the end-user. Our software engineering team custom-codes the firmware to govern your specific Constant Current (CC) or Constant Voltage (CV) algorithms. Furthermore, we design custom digital touchscreen interfaces and LCD menus, ensuring the UI perfectly matches your brand’s operational logic.
- Environmental Hardening: Electronics fail in pump rooms. To combat salt mist and trace chlorine gas, every PCB that leaves our factory line undergoes rigorous conformal coating. We apply thick, industrial-grade polymer sealants over the circuitry, ensuring long-term survival in aggressive chemical atmospheres.
Why Partner with a Custom Rectifier Manufacturer?
Procuring generic power supplies from standard electrical vendors often leads to catastrophic failure rates. Generic manufacturers do not understand the highly specific V/I (Voltage/Current) curves required to drive titanium MMO (Mixed Metal Oxide) plates, nor do they understand the corrosive realities of a brine environment.
By partnering with Century as your custom rectifier manufacturer, you are working with engineers who build both the titanium anode and the power supply. We perfectly match the SMPS frequency and ripple coefficient of our rectifiers to the exact coating formulation of your cell. This holistic approach prevents premature erosion of the expensive ruthenium/iridium coatings on your plates.
Additionally, we operate strictly under Non-Disclosure Agreements (NDAs). We protect your electrical schematics, provide full private-labeling (including custom molded logos, branded bezels, and bespoke packaging), and support your team through UL, CE, or ETL certification processes.
Not necessarily. If you have full gerber files and schematics, we can act strictly as your contract manufacturer. If you only have the titanium cell parameters, our in-house electrical engineering team can design the power supply architecture from the ground up for you.
Yes. We can configure the primary AC input stages for any global standard, including 110V/220V single-phase for North America, 230V/240V for Europe/Australia, and 3-Phase 380V/480V for heavy industrial applications.
For modifications to our existing platforms (such as custom UI, branding, or minor logic tweaks), prototypes can be delivered in 2 to 3 weeks. For completely ground-up PCB and enclosure designs, prototyping typically requires 30 to 45 days.
