DC Input AC Load 3 Phase Solid State Relays

● Three phase solid state relay● 5-32Vdc input● 24~480Vac load● only available with 10/25/40 amps● Zero-crossing trigger● For resistive load only

● Three phase solid state relay● 90~280Vac Input● 24~480Vac load● From 10 amps up to 200 amps● Zero-crossing trigger

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.

● MW-DE-50● Size:50mm*94mm*80mm● Heatsink for 80A/100A/120A SSR● Panel mount and Din rail mount with clamps● Aluminum heatsink● For single phase SSR

The MWH300F-692 is a versatile dual-mode intelligent controller supporting both PID temperature control (thermocouple/RTD) and SCR process control (analog voltage/current). It features real-time 3-phase current/voltage monitoring, a bright dual-row digital display, and comprehensive safety protections including over-temperature, over-current cut-off, heater break/short alarm, and 3-phase unbalance detection. With RS-485 communication, PID auto-tuning, and a rugged industrial design, it ensures precise and reliable performance in harsh environments.  

● MW-W-70● Heatsink for 40A SSR● Panel mount only● Aluminum heatsink● For single phase SSR
