Alinan 2pcs SSR-25DD Solid State Relay DC to DC Input 3-32VDC Output 5-200VDC Single Phase Solid State Relay

The Alinan 2pcs SSR-100DD Solid State Relay has drawn a mixed reception from customers, with many expressing dissatisfaction regarding its performance and reliability. Users have voiced significant concerns about the relay's actual output capabilities, particularly with claims of overheating and inadequate build quality. One reviewer noted that despite the relay being rated for 100A, it became inoperable when subjected to loads around 60A, suggesting a severe under-specification in the internal components, particularly the mosfet, which may not handle the expected electric load. Moreover, multiple users experienced failures when applying low voltage signals, describing how the relay either became unresponsive or stuck in a closed position shortly after activation. One user pointed out the lack of a terminal cover as a design flaw, indicating a need for additional safety and usability features. Overall, while some have noted that the relay works initially, the Consensus leans heavily towards skepticism regarding its reliability for heavy-duty applications. The combination of potential overheating, questionable engineering, and failure under load makes the Alinan SSR-100DD a concerning choice for those needing robust solid state relays for significant loads. **
