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 TC-K14B is a fast-response K-type thermocouple engineered for applications where rapid, accurate temperature measurement is essential. Unlike conventional sheathed thermocouples, the TC-K14B features an exposed welded-bead junction with minimal thermal mass, enabling it to detect temperature changes within fractions of a second. This makes it the preferred choice for dynamic temperature monitoring tasks in research, testing, and industrial quality control environments. The sensor is constructed from a fine-gauge Chromel-Alumel (K-type) thermocouple wire pair, twisted together and insulated with a flexible fiberglass braid. The green-and-white color coding of the lead wire follows the international K-type thermocouple standard, providing clear polarity identification. The fiberglass insulation offers excellent thermal resistance and flexibility, allowing the sensor to be routed through confined spaces and around complex geometries without risk of insulation damage. At the instrument end, the TC-K14B is fitted with a standard miniature K-type quick-disconnect connector (green housing, labeled 'K NiCr+ / NiAl−'), which is compatible with a wide range of handheld thermometers, data loggers, and temperature indicators that accept the IEC 60584 / ANSI miniature thermocouple connector standard. The plug-and-play design eliminates the need for field wiring, enabling rapid deployment and sensor replacement without tools or specialist knowledge. The lead wire length is fully customizable, making the TC-K14B adaptable to installations where the measurement point is located at a significant distance from the instrument. As part of the PIDMaxWell range of temperature measurement solutions, the TC-K14B is designed to integrate seamlessly with PIDMaxWell PID temperature controllers, temperature transmitters, and compatible third-party instrumentation.  

MF43H is a touch screen ramp and soak controller, the conventional ramp and soak controllers or some call it profile controllers on the markets are configured via set buttons on the front panel. end user have to go through layers upon layers of parmaeters and navigate through different parameter during the configuration process. the process could be painful and stressed and often times lead to less efficient and frustration. the configuration with our touch screen ramp and soak controller is much more easier, it's easier for end user to pick up the process as they operate the controller like a cell phone. below are some of the basic features with this touch screen ramp and soak profile controller

● Screw-in nozzle thermocouple type● M6,M8, ¼ BSP, 1/4NPT etc● Stainless steel ,silicon wire, Teflon wire etc● Available with grounded and ungrounded configuration● 304,316,310 Stainless steel, brass and Alumimun● High temperature-resistant compensating cable, PVC cable, Silicone cable, PTFE cable, metal braiding cable with mica- fiber, metal braiding cable with glass-fiber.

  The Maxwell MS-1VD2238 Series is a highly cost-effective, high-accuracy single-phase isolated SCR power regulator designed for precise phase angle control. Featuring a versatile multi-input design, this advanced thyristor module simultaneously supports 0-5Vdc, 0-10Vdc, 4-20mA, and potentiometer control signals without requiring hardware modifications. Engineered with optical isolation between the input and output circuits, it ensures maximum operational safety and signal integrity. Available in a wide current range from 10A to 200A for both 220Vac and 380Vac loads, the MS-1VD2238 series incorporates a built-in soft start circuit and an internal buffer (snubber) to protect against voltage surges. Housed in a durable, fire-retardant enclosure with resin sealing, this panel-mounted regulator is the ideal solution for controlling resistive heating elements in demanding industrial environments.

The PIDMaxWell FL380-D25-L is a robust 25A single-phase AC solid state relay designed for reliable industrial performance. Featuring a 4-32VDC control input and a 24-380VAC load voltage range, it delivers fast, silent switching with ultra-low 5mA off-state leakage and high 4000V isolation. Ideal for demanding heating, lighting, and temperature control applications, it operates efficiently across a wide -30°C to +80°C range (a proper heatsink is required for full 25A load).
