? Product Overview

The Mager MGE-30323840Z is a high-performance, three-phase solid state relay (SSR) designed for industrial applications requiring reliable and fast switching of AC loads. With a DC control voltage range of 3–32V and a load capacity of up to 40A, this SSR is ideal for controlling heavy-duty equipment such as motors, heaters, and lighting systems. Its zero-crossing trigger control method ensures minimal electrical noise and extends the lifespan of connected devices.​UrukTech+4Mechblock+4robosavvy.co.uk+4

?️ Installation & Cooling Recommendations

• Heat Dissipation: For load currents exceeding 10A, it is recommended to use a heat sink. For currents above 40A, an air-cooled or water-cooled radiator should be installed to ensure optimal performance and longevity.

• Inductive Loads: When controlling inductive loads, connect a varistor in parallel with the output terminals. The varistor's voltage rating should be 1.6 to 1.9 times the load voltage to protect against voltage spikes.​HUIMU electronics

? Applications

• Industrial Automation: Control of motors, conveyors, and robotic systems.

• Heating Systems: Regulation of industrial heaters and ovens.

• Lighting Control: Management of large-scale lighting installations.

• HVAC Systems: Operation of fans, compressors, and pumps.
