The MaxWell MS-3DA4880 is a heavy-duty 80A Three-Phase Solid State Relay (DC to AC), designed for reliable control of 24-680VAC loads. This ready-to-use kit comes fully pre-assembled with a customized heavy-duty aluminum heatsink and a high-velocity cooling fan, ensuring optimal thermal management and continuous operation under heavy loads. Featuring advanced Back-to-Back SCR technology, Zero-Crossing switching, and a built-in RC snubber circuit, it delivers superior surge protection, minimal EMI, and long-term stability. Ideal for industrial heaters, HVAC systems, and plastic machinery, it is CE certified, fully resin-sealed for 3500V high isolation, and engineered for plug-and-play safety and performance.

IoT is getting more and more popular, to keep up with the trend, for some of temperature control system with PLC in it, we offer an alternative solution by using our DIN rail temperature controller plus our IoT box, or IoT HMI, the concept is implementing DIN rail temperature controller system and connect it with IoT HMI plus various I/O modulars, so that the PLC can be eliminated from the system, 

Simple but accurate 3 digits display, for application less than 1000 degree C or F, Thermocouple and RTD input to accommodate most of applications, touch button which do not wear out over time, perfect for demanding situation, advanced control algorithm to achieve perfect control accuracy with limited overshoot and undershoot, 3 years warranty, relay and SSR Drive output on the same device, large and high visibility LED display, two options on the display, white+green or red +yellow, Simple and easy to use is the concept of this controller, very limited parameters to reduce the workload on configuration. CE and ROHS compliant.
