Medium voltage thyristor ATDK1210MA480 AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for medium voltage SCR thyristor K1210MA480 IXYS UK Westcode, Littelfuse.
Average forward on-state current ITAV – 1210 ampere, repetitive peak forward and reverse voltage VDRM/VRRM – 4800V.
Features: Medium Voltage Thyristors are optimised for medium voltage applications and series operation. As voltages increase, so do switching losses and turn-off time to a point where they become significant in line frequency applications. Distributed gate architecture ensures excellent switching performance over a wide range of voltage, current and di/dt.
Thyristor lifetime is also engineered to achieve an optimum balance between conduction losses, commutation losses and turn-off time to give maximum power handling from line frequency to 400Hz. This also gives significant benefits when series or parallel connection of devices is required.
Medium voltage thyristors are available from 2800V up to 6500V and current from 450A up to 4215A making them particularly suitable for high power converters such as medium voltage DC drives, medium voltage soft starts and utility applications such as HVDC, static VAR compensators, excitation and transfer switches.
"Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series" for thyristor cooling are also available to order.
Thyristors AS ENERGITM have the following features: low static and dynamic losses, high values of VDRM/VRRM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 10 to 15000 A, high resistance to thermal and electric cycling, natural or forced air cooling.
The technical specifications and parameters of K1210MA480 and replacement ATDK1210MA480, datasheet PDF, outline drawing and dimensions are listed below.
Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide technical passport and certificate of conformity.
The final price for medium voltage SCR thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
