SCR power regulator 3 phase advanced digital type HGW8 300A and 350A

HGW8 Series Three-Phase full functional SCR Power Regulator

Product Features

◎ Full-function, fully intelligent SCR power regulator, supporting phase-through, constant current, constant voltage, constant power, zero-crossing, phase zero-crossing control with direct switching.

◎ Multiple setpoint mode options: analog, digital, communication setting, or direct keyboard setting.

◎ Intelligent protection functions, including phase loss, overtemperature, overcurrent, load wire break, load imbalance, and power frequency fault protection.

◎ Excellent output linearity. Precisely controlled by the microcontroller for duty cycle, with real-time display of load current, voltage, and power for monitoring the regulator's working status at any time.

◎ MODBUS RTU communication function, enabling networked control with HMI, PLC, etc., for remote monitoring.

◎ Suitable for various load types, such as resistive loads, silicon carbide rod loads, transformer loads, silicon molybdenum rod loads, with loads connectable to neutral wire.

◎ Up to two analog input channels, with direct switching between current and voltage signals.

◎ Parameter saving function after on-site debugging, allowing customization of specific parameter settings.

◎ One-key restore to factory defaults function, restoring to factory values or specific parameter settings to avoid faults caused by unauthorized on-site parameter modifications.

◎ Dual-row digital display, with customizable content on the upper and lower rows; the lower row can directly switch via keys to display input, output, voltage, current, power.

◎ Detachable display panel, installable on the control cabinet panel for direct monitoring of working status.

◎ Load current coverage from 30A to 450A, suitable for various heating power applications.

◎ No deformation after long-term use.

◎ Precision CNC-formed aluminum body, sturdy and durable, no deformation after long-term use, no loosening.

◎ All series come standard with high-speed DC fans or dual ball-bearing axial fans, long lifespan, fast heat dissipation, safe and reliable.

Control mode selectable: P - phase angle constant voltage with current limiting; C - constant current; CV - constant power; Z - zero crossing cycle power regulating; ZV - fixed cycle zero crossing power regulating.
