Ensure power integrity and system security. Explore our premium selection of DC solar fuses, surge protectors, combiners, and connectors designed for global export.
In today's complex renewable grid systems, relay modules serve as the nervous system's key switches. Actuating signal controls, separating low-voltage intelligence circuits from high-voltage energy flows, and executing rapid automated disconnections require relay mechanisms engineered with absolute precision. High contact reliability, optoelectronic isolation, and rugged housing components prevent dielectric breakdown and maximize uptime.
As a specialized segment within Wenzhou Phlox Energy's comprehensive solar protection and electrical distribution suite, our custom OEM/ODM relay module assemblies are manufactured to excel. Integrating modern design architecture, we provide global markets with relay setups that boast minimal loop losses, high breaking capacities, and swift reaction windows under peak fault loads.
With more than 10 years of specialized manufacturing experience, Wenzhou Phlox Energy Co., Ltd. supplies high-caliber electrical protection solutions that support clean energy transition across 3,900+ global installations.

Transitioning from concepts to scalable, hardened electrical controls. We support high-frequency engineering changes, customized terminal wiring profiles, and branding integration.
Our R&D team works closely with engineering buyers to modify board dimensions, pin configurations, contact configurations (SPDT, DPDT), and operating threshold voltages to align with proprietary PLCs and RTUs.
Designed to endure severe surge events. Features integrated protection varistors (MOVs), TVS diodes, and high-performance optocouplers that block disruptive electrical noise and protect expensive downstream microcontrollers.
Equipped with onboard LED indicators for direct switching state visibility and mechanical indicators for swift physical inspections. Essential for rapid remote diagnosis and troubleshooting cycles.
Where reliability meets harsh real-world environments. Our electrical and control components are engineered for continuous operational success.
Wenzhou Phlox Energy operates from Wenzhou, China's premiere electrical manufacturing hub. This location enables us to secure premium raw copper, engineering grade polycarbonates, and high-frequency PCBs at optimal cost structures. The geographic cluster effect provides an agile response loop for customized prototype modifications and high-volume orders.
Our 11,500 square meter factory floor maintains vertical integration from raw material shearing to finished functional testing. This reduces production lead times and limits reliance on external component suppliers.
More than 100 automated machines ensure mechanical assembly consistency, precision wiring, and repeatable calibration metrics for every relay and fuse carrier.
Every product undergoes strict inspection cycles, including insulation testing, dielectric resistance verification, and heat cycle aging prior to packaging.
