H3DK-GA DC12 OMRON

The H3DK-GA DC12 by Omron is a versatile star-delta timer designed for motor control applications. It operates on a 12 VDC power supply, ensuring compatibility with various control systems. This timer features two SPDT (Single Pole Double Throw) outputs, one dedicated to the start operation circuit and the other to the delta operation circuit, providing precise control over motor transitions. The H3DK-GA DC12 offers a selectable time range from 1 to 12 seconds, adjustable across two ranges, allowing for fine-tuning of the star-delta transition timing. Its primary function is to facilitate the smooth transition from star to delta connection in three-phase motors, reducing inrush current and mechanical stress during startup. The device utilizes convenient terminal blocks for easy and secure wiring. This timer is ideal for applications requiring controlled motor starting, such as pumps, fans, and compressors. By implementing a star-delta starting method, the H3DK-GA DC12 helps extend the lifespan of motors and connected equipment. Its compact design and reliable performance make it a valuable component in motor control panels.
