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.

PIDMaxWell TH100 is a dual-loop temperature and humidity controller with 2 independent relay outputs. It simultaneously monitors and controls both parameters with dedicated outputs for heating, cooling, humidifying, and dehumidifying. Features RS-485 Modbus-RTU communication for remote monitoring. Large dual-LED display shows temperature and humidity at the same time. Wide range: -15℃~85℃ temp, 0~100% RH. Ideal for greenhouses, warehouses, cleanrooms, and HVAC systems. CE certified.
