Working Principle

The F1891DH1200 is a thyristor module, which works on the principle of SCR (silicon-controlled rectifier) switching. It is basically a three-terminal device that controls the flow of electric current, depending upon the control signal being applied to it. The F1891DH1200 comprises of two terminals, anode and cathode and a control terminal, known as gate. Current flows between anode and cathode terminals when positive gate signal is applied, whereas current stops flowing between anode and cathode when the gate signal is removed.

The F1891DH1200 can be used in several switching configurations, depending upon the application. The module can be used in On-Off Switching, Phase Control, Speed Control and Soft-Start configurations. The control signal applied to the F1891DH1200 module is either DC control or transistor based control signal.

The F1891DH1200 offers several advantages over traditional switching methods, like low noise, fast turn-ON and turn-OFF characteristics, high efficiency and improved reliability. The module is designed for 800 Amperes continuous use with up to 400 turns of On/Off cycles. The module is highly reliable and offers long life, making it ideal for industrial applications.
