Stud Power Phase Control Thyristors SCR 100A - 400A

Power Phase Control Thyristors by LJ-MD, also referred to as Silicon Controlled Rectifiers (SCRs), in stud design are versatile thyristors capable of regulating and converting both DC and AC currents up to 400A at frequencies of up to 500 Hz. These thyristors operate within circuits with voltages reaching up to 4400V, with variations across different series. The T series of high-power stud thyristors offers a range of current options from 100A to 400A, catering to various industrial applications.

The thyristors feature an industry-standard ceramic housing, facilitating seamless integration into existing equipment setups. Polarity identification is simplified by symbols on the case, with the base serving as the Anode, the flexible power lead as the Cathode, and the control electrode (Gate) being represented by the flexible wire exiting the case. Technical specifications, part numbering guidelines, polarity indications, dimensions, and recommended cooling methods are detailed for easy reference.

These thyristors are designed with a sealed housing, safeguarding the functional components and semiconductor elements against mechanical impacts and environmental factors. The stud design, coupled with a flexible power lead, enhances versatility, allowing for usage in applications involving moving parts. With features such as low static and dynamic losses, high VDRM/VRRM values, and a wide voltage and amperage range, these thyristors offer reliable performance across various industries.

LJ-MD ensures product quality and provides technical documentation and certificates of conformity as needed. The pricing for phase control stud thyristors is determined by factors such as voltage class, quantity, delivery terms, manufacturer, country of origin, and payment method.
