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.

The PT100-8 is a probe-type Platinum Resistance Thermometer (PT100 RTD) distinguished by its adjustable insertion depth — a key feature that sets it apart from fixed-length sensors. A stainless steel compression fitting is integrated into the assembly, forming a liquid-tight or pressure-tight seal against the process wall while allowing the operator to slide and lock the probe at any desired insertion depth before or after installation. This eliminates the need to specify a fixed immersion length at the time of ordering and greatly simplifies retrofitting into existing equipment. The probe is constructed from 304 stainless steel and is available in diameters of 4 mm, 5 mm, and 6 mm. The lead cable is shielded with a metal braid and covered with PTFE insulation, delivering low noise, high mechanical strength, and excellent resistance to elevated temperatures. The PT100-8 is compatible with a wide range of process fittings — including NPT, BSP, and metric threads — and is available in a waterproof configuration, making it suitable for measuring the temperature of both air and liquids across diverse industrial environments.

The MW30E series is an advanced, three-phase power regulator (current range: 25–1500A), Suitable for both resistive and inductive loads 1. Rating from 25A all the way up to 1500A2. 0-5V/0-10V/0-20mA/4-20mA analog input, 3 digital inputs, 1 digital output, Modbus-RTU3. Phase angle firing control mode or burst-firing mode configurable4. Work with load on Star, Delta or Star with netural wire5. Modbus RS-485 available as default,  other communication like profibus DP, Ethernet can be custom made6. Different control mode, Constant Voltage (V) / Constant Current (I) / Constant Power (P)/Open-loop7.100% load can be applied to the SCR according to the rating, for example, 100 amps rating SCR, you can apply 100 amps to phase current. there is no need to take the derating into consideration
