Phase Control Thyristor T261-160 AS ENERGITM is general purpose stud thyristor, also known as Silicon Controlled Rectifier (SCR). This is a power thyristor designed for converting and control DC and AC currents up to 160A with frequency up to 500Hz in circuits with voltages up to 100V – 1800V (voltage class from 1 to 18). Thyristor package type – ST6, mounting standard thread – М20х1.5, (on request, UNF thread 3/4"-16UNF-2A), weight – 240 g.
Thyristors are supplied in stud design. The base of the thyristor is the Anode, the flexible power lead is the Cathode, the flexible wire exiting the base of the power lead is the auxiliary cathode, the flexible wire exiting the case is the control electrode (Gate). This SCR thyristor can be an alternative product, replacement, analog, equivalent for other types thyristors 130A, 140A, 150A, 160 amp in a stud housing.
Air and water heat sinks are used to cool the thyristors. To provide reliable thermal and electrical contact with the heatsink a tightening torque Md must be observed during assembly. For better heat dissipation of thyristor during assembly, heat conducting paste is used.
The thyristors have a hermetic ceramic housing isolating the functional part and the semiconductor element from mechanical impacts and environment. Stud screw fit thyristor with a flexible power lead. Stud thyristors are notable for their ability to be used on moving parts.
