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.

Heatsinks for 3 phase SSR, compatible with 10A/25A solid state relay, it's a radiator to help the SSR cool down while operating.

The Maxwell TME310-A0NN Series is an advanced, highly reliable head-mounted smart temperature transmitter designed for universal industrial applications. Engineered to fit standard DIN B connection heads, this loop-powered device seamlessly converts signals from a wide array of sensors — including RTDs, Thermocouples (TC), resistance, and voltage (mV) inputs — into a stable, scalable 4-20mA analog output superimposed with the HART 7 digital communication protocol. Equipped with a clear, rotatable 4-digit LCD display and an intuitive 3-button interface, the TME310 allows for effortless local configuration and real-time process monitoring without the need for external communicators. Its robust design ensures exceptional measurement accuracy (±0.1°C typical for Pt100), outstanding long-term stability, and comprehensive diagnostic capabilities compliant with NAMUR NE 107 standards. Whether configured locally, via a HART handheld device, or through PC software, the TME310 delivers precise, dependable temperature measurement for the most demanding process control environments.

The MKD2 Series is a single-phase, dual-channel, DC-controlled AC solid state relay (SSR) designed for reliable, silent switching of resistive and inductive AC loads in industrial and commercial control systems. Each unit houses two independent switching channels within a single compact black housing, enabling two separate AC loads to be controlled simultaneously from a single device — saving panel space and wiring time compared to installing two separate SSRs. The MKD2 accepts a DC control voltage of 4–32 VDC, making it directly compatible with PLC outputs, microcontroller I/O, and standard industrial control signals. The AC load side supports voltages from 24 to 480 VAC, covering 110 V, 220 V, 380 V, and 480 V systems worldwide. Load current ratings of 25 A, 40 A, 60 A, and 80 A are available, with all variants sharing the same physical footprint for easy interchangeability. Zero-crossing trigger technology ensures that switching occurs at the natural zero-crossing point of the AC waveform, minimising electrical interference (EMI) and extending the service life of both the relay and the connected load. Individual LED status indicators for each channel provide instant visual confirmation of relay state, simplifying commissioning and fault-finding. The unit is CE certified and constructed from fire-retardant ABS with a dielectric strength of 2500 Vrms between input, output, and base.
