AdoptST main chip, Fairchild optocoupler, TI power supply, pure copper transformer, far superior in mainboard reliability compared to domestic counterparts. Uses Taiwan Delta DC 6400 fan, operates only when the regulator has signal input, significantly extending fan lifespan. No need for 220V control voltage, compatible with various voltage levels. Main circuit can operate at 220V, 380V, 480V, 660V, etc., with applicable frequency of 35-70HZ. Regulator features soft start and soft stop functions. Utilizes Siemens thyristors, with low heat generation, ensuring the machine does not overheat. Current range: 20A, 30A, 40A, 50A, 60A, 75A, 80A, 90A, 100A, 120A, 150A, 175A, 200A, 250A, 300A, 350A, 400A, 450A, 500A, 600A, 700A, 800A, 900A, 1000A, 1500A, 2000A, 3000A, 4000A, 5000A. Full functionality, four-line LCD display, showing state of power regulator, start/stop control method, input/output ratios, rated voltage and current, runtime, etc., with bilingual interface. Standard phase, constant voltage, constant current, constant power, zero position, phase + zero position control can be directly switched, with multiple setpoint modes available: analog, digital, communication settings, direct keyboard input. Smart protection features include missing phase, overtemperature, overcurrent, load wire breakage, unbalanced load. In case of thyristor breakdown in the power regulator, the relay closes, allowing for tripping signal to the circuit breaker, eliminating the need for fast-blow fuses to reduce costs. High output linearity, precisely controlled by a microcontroller, displaying real-time load current, voltage, and power percentages, enabling continuous monitoring of the power regulator's status, suitable for various load types such as resistive loads, silicon carbide rods, transformers, silicon molybdenum rod loads, with the load center capable of connecting the neutral wire. Input control signals: 4-20MA, 0-20MA, 0-5V, 0-10V, potentiometers, etc. Load current range: 20-5000A, fully covered, suitable for various heating power applications.
