It integrates power regulation and voltage regulation functions. Adopting imported components and high-precision digital circuit control, single-phase 50A dual-communication SCR controller features longer service life, safety and reliability. Equipped with a digital display, it enables more convenient on-site modification of control parameters.single-phase 50A dual-communication SCR controller supports multiple input signals and is equipped with soft start and soft stop functions. Optional features include 2-channel Modbus RTU communication, true RMS voltage/current display, and DA analog output function; single-phase models come standard with 2-channel DO (Digital Output).
single-phase 50A dual-communication SCR controller is widely used in scenarios such as lighting adjustment in stages and KTVs, speed regulation of single-phase motors, and heating power control.
