Vetrix V7T Three Phase Digital Thyristor Power Regulator (380Amp)

Our thyristor solutions meet your toughest design challenges. V7 Series ensures high product quality and reproducibility in applications ranging from simple to complex. With over 30 years of history, their precision and reliability are proven for any industrial manufacturing process requiring exacting material melting, heating, drying, or forming. It contains high-speed fuses to prevent damage to the main components when anomalies occur, freeing external wiring and reducing installation space.

Thyristor power controllers (SCR power controllers) control power or voltage supplied to a load. Typical applications are generally found where power needs to be varied and ultimately converted into thermal energy. For example, the controllers are used in industrial furnace construction or in plastic processing. Thyristor power controllers are operated with an alternating voltage in single-phase or three-phase. They are controlled by a controller and vary the activation time of the mains voltage for the load. Where the operating conditions do not require otherwise, the pulse group operation is recommended.

• During normal operation of the controller, information from the Operation Box Display can be planned as: By Input Percentage, Output Percentage, Buffered Rise Time, Buffered Drop Time, Maximum Output Limit, Voltage Output, Current Output, Power Output, Fin Temperature, Power Source Frequency, External Analog Input Percentage, Value of Digital Input, Operation Time, etc.
• Single Chip Control, input resolution 10-bit, output resolution 0.1%, multiple parameters to accommodate user settings to meet requirements.
• One port is provided for attaching an RS-485 Com, an Analog Output (0-20 or 4-20mA), or an additional multi-function contact (electronic contact).
• Signals such as 4-20mA, 1-5VDC, 2-10VDC, 0-20mA, 0-5VDC, 0-10VDC, isolated contact, Operation Box Input, COM Command (actual value or percentage) …etc., available for any kind of control signal.
• Two Analog Signal Inputs can be defined for multiple functions: Anomaly Reset, Basic Output, Manual Setting, Maximum Output Limit, Manual/Auto Switch-over, Phase/Zero Distribution Switch-over, Phase/Zero Sampling Switch-over, Voltage Limit, Current Limit, etc.
• Nine Control Modes: Phase Angle Control Proportion Output, Zero Cycle Sampling, Zero Time Sampling, Phase Start Up? Zero Cycle Operation, Phase Start Up? Zero Time Operation, Constant Phase Voltage, Phase Current Limit, and Constant Phase Power for meeting various applications – one single machine satisfies all your thermal load needs.
• Equipped with Anomaly Detection including Fuse break, over-current, over-temperature, Temperature Sensor Anomaly, Current Detection, Low-current Detection, Load Decline Detection, load wire breakage, phase unbalance, voltage feedback anomaly, EEPROM Anomaly, etc., providing real-time protection against anomalies, together with 4 sets of anomaly records.
• Multi-function Dry Contact can be defined as a Dry Anomaly Contact (NO), a Dry Anomaly Contact (NC), an Operation Contract, or a Current Detection Contact.

Applications

With a single-phase power regulator, and a three-phase power regulator, this can be used to control the heat source in the electric furnace, thermostatic bath, food, chemical, air-conditioning, and plastic molding.
