ProtectionAdopts integrated module control unit with accurate control precision, designed with dual-loop control and protection, featuring overshoot, undershoot, thermocouple break, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start protection.
ControlUses closed-loop thyristor module trigger control (phase-shift trigger mode). Output voltage, current, or power is continuously adjustable with constant voltage, current, or power characteristics. The current loop is the inner loop and the voltage loop is the outer loop. When the load is suddenly applied or exceeds the current limit, the output current is limited within the rated range to protect heating elements from excessive current/voltage impact, ensuring safe and reliable control effect and precision.
Display ParametersTemperature, temperature segment number, segment time, remaining time, output power percentage, voltage, current, etc.
ButtonsImported buttons with a service life of over 100,000 times, equipped with LED indicators
Temperature Curve SettingAdopts intelligent temperature controller with multiple regulation modes (standard PID, artificial intelligence adjustment APID, MPT, etc.), featuring self-tuning and self-learning functions, no overshoot/undershoot, and 10-100 segment program control. It supports arbitrary slope heating/cooling control, with programmable commands (jump/cycle, run, pause, stop) and allows in-operation program modification. Equipped with AI adjustment algorithm with curve fitting function for smooth curve control.
