Bi-directionally Controlled Thyristors 5STB ABB Replacement
Power phase control thyristors, also known as Thyristor SCR (Silicon Controlled Rectifier), in disc design are press pack type general-purpose thyristors, regulating and converting DC and AC currents to 2630A in circuits with voltages to 6500V (depends on the thyristor type).
Thyristors ATB JY ENERGITM are a replacement, analog, alternative for Bi-directionally Controlled Thyristors 5STB ABB, Hitachi Energy.
“Air-cooled heatsinks O series for disc devices”, “Air heatsink SF series”, “Water heatsink SS series” for thyristor cooling are also available to order.
Features Bi-directionally Controlled Thyristors: Two anti-parallel thyristors on one Si-wafer; Patented free-floating silicon technology;Designed for high power industrial and energy management applications; Matched Qrr values available for series connection. The thyristor has an industry standard ceramic housing making it easy to integrate the device into existing equipment. This thyristor has a disc housing with pressure contacts. The polarity of the thyristor is determined by the icon on the case. The technical specifications, part numbering guide, datashets for thyristors are listed below. 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 100 to 15000 A, high resistance to thermal and electric cycling, natural or forced air cooling. 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 of phase control thyristors depends on the voltage class, quantity, delivery terms, manufacturer, country of origin and form of payment.
