Q What are the core technical specifications of this solid state relay?
This single-phase solid state relay (model XSSR-DA4840W1) operates with a control voltage range of 3-32VDC and a control current of 6-25mA. It handles a load voltage of 75-480VAC with a maximum load current of 40A, functioning within a 50-60Hz frequency range.
Q Does the relay require an external heatsink during operation?
Yes. For applications operating close to the maximum 40A load current, mounting the solid state relay on a compatible heatsink is highly recommended to dissipate heat effectively and ensure long-term operational stability.
Q What is the operational temperature range for this unit?
The product is rated to operate reliably in ambient temperatures ranging from -20°C to 70°C, making it highly versatile for demanding industrial environments.
Q Which safety and compliance certifications does this relay carry?
The manufacturing system is ISO9001 approved. The products conform to multiple rigorous global standards, holding certifications such as CE (EU), UL (US), TUV (Germany), CCC (China), KC (South Korea), and RoHS directive compliance.
Q Can I use this solid state relay on both 50Hz and 60Hz networks?
Absolutely. The relay is rated for a frequency range of 50-60Hz, allowing it to seamlessly run on both standard electrical frequency configurations worldwide.
