Import 12v Solid State Relay 40da — Buy in wholesale FOB from Supplier in China

This 12V solid state relay, model SSR-40DA, is a miniature, epoxy-sealed switching device designed for general-purpose control applications. It operates with a control voltage range of 3-32VDC and a control current of 3-25mA, switching a load voltage of 90-480VAC. The relay handles load currents from 10A up to 90A, with a fast on-off switching time of 10ms and an off-state leakage current of just 2mA. Its insulation resistance is rated at 1000MΩ at 500VDC, and it functions reliably across an ambient temperature range of -30°C to +75°C.

Solid state relays like this SSR-40DA use semiconductor components instead of mechanical contacts, offering silent operation, no contact bounce, and a longer service life in environments with frequent switching. The epoxy encapsulation provides protection against dust and moisture, a standard feature for industrial-grade SSRs. Typical applications for relays in this current class include temperature control in ovens and furnaces, motor speed regulation, lighting control systems, and power supply switching in automation equipment. The miniature form factor allows for dense panel mounting.

Industrial automation integrators, HVAC system builders, and equipment manufacturers source these relays for their reliability in controlling resistive and inductive loads. Zhejiang Huapu Explosion-Proof Electric Co., Ltd. is based in Yueqing, Zhejiang, a region known for electrical component manufacturing. Buyers should confirm the specific load current rating required for their application, as the listing provides multiple options from 10A to 90A. Packaging specifications and bulk order lead times are not detailed in the listing and should be verified directly with the supplier before placing an order.

Zhejiang Huapu Explosion-Proof Electric Co., Ltd. is located in Liushi Town, Yueqing, Zhejiang, China. The company's address places it within the Yueqing region, a major hub for low-voltage electrical component manufacturing in China. The supplier is listed on the platform with a 'harbor' trust tier, but the listing does not provide data on response rate or average response time, both currently showing as zero.

The listing describes the supplier as producing a solid state relay with a miniature design and epoxy protection. No further company profile details, such as founding year, employee count, production capacity, or specific certifications, are provided in the available data. The product description focuses on the technical specifications of the SSR-40DA model. Buyers seeking information on the company's quality management systems, export experience, or factory audit status would need to request this directly from Zhejiang Huapu.
