Module Semikron SKKD 260/22 H4 is a dual diode rectifier module in a standard housing SEMIPACK 3.
Rectifier Diode Module AMKD 260-22 H4 AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for diode module SKKD 260/22 H4 Semikron.
The diode modules are characterized by high electrical and thermal cycling capability, meaning high reliability and long lifetime in intensive operation modes. The diode modules are housed in a industry-standard housing making it easy to integrate the device into existing equipment.
The main (power) terminals are on the top of the case and are marked as 1, 2, 3 (common anode-cathode, cathode, anode).
Dual diode modules are used in various power equipment - power and control units, power regulators, AC regulators, DC motors control, AC motor soft starters, converters, controllers of blast furnaces or chemical processes, welding equipment, and as rectifiers for AC converters.
Modules are offered in several dual and single device topologies for almost all phase control or rectifier applications.
Our company provides a quality guarantee for thyristor / diode modules of 2 years from the date of purchase. When supplying thyristor / diode modules, if necessary, we provide technical passport and certificate of conformity.
The final price for thyristor / diode modules depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.
