3. Core Functions & Features
-
High-Gain Pulse Amplification
Amplifies weak trigger signals from the control system to sufficient amplitude to drive thyristors, IGBTs, and power switches.
-
Precise Signal Shaping & Isolation
Shapes input signals into clean, sharp trigger pulses; provides electrical isolation between control and power circuits.
-
Fast Response & Low Noise
Ensures rapid response to control commands; low noise design maintains signal integrity in harsh industrial environments.
-
Overload Protection & Recovery
Built-in protection against signal overload; fast baseline recovery prevents amplifier blocking.
