Adaptable OEM & ODM Solutions

Private Labelling

Launch your own branded SPD line without building a factory. We apply your logo directly to SPD modules and print custom labels across your full product range — giving your distribution network a consistent, professional brand identity from day one.

Hardware Customisation

Need SPDs tuned to a specific voltage system, protection mode, or local grid standard? Our engineering team works from your technical brief — adjusting parameters, developing custom housings via in-house mold production, and validating performance to IEC standards before mass production begins.

Packaging Design

We provide unbranded technical datasheets ready for your own co-branding, along with custom outer packaging designed to your specifications. Whether you need plain export cartons or presentation-ready product boxes, we coordinate packaging to match your delivery and channel requirements.
