Ascon Thyristors

Microprocessor Based Thyristor Power Controllers

Lines TH-S, TH-A, TH-P


These power controller lines by Ascon meet the most common requirements, offering a complete set of single phase, three-phase economy and three-phase power controllers with a wide range of nominal voltages and currents.

The different operation modes, such as the phase angle operation, wave train and MOSI for Super KANTAL, allow use with any load. Internal diagnostic and load monitoring functions ensure safe operation. 

The TH-S line:
For heating processes with resistive or infrared loads ThyroS can be used as an enhanced static switch with zero crossing capacities. TH-S has no mechanical moving parts, resulting in maintenance-free operation. Zero crossing operation offers the benefit of being free of line noise harmonies. Fine adjustment can be obtained operating with free DC components half waves operation. A wide range of power and current ratings are available.

TH-S Line Features:

• Compact: Compact in size, and can be easily mounted on a DIN rail inside an electrical cabinet.
• Complete: Supplied with all the necessary thyristor accessories so no options are needed.
• Safe: Control is obtained by emitting the calculated number of full waves, no DC components are generated. Oversized Thyristors assure high resistance to current and temperature overloads.
• Easy and fast installation: Only power and a control signal are necessary; no external load protection fuses are needed.
• Diagnostic functions: The ThyroS can be equipped to detect total or partial load failure. It can also be equipped with fuse failure indication.
• Open Communications: Each ThyroS can be equipped with Modbus RTU, Profibus DP and CANopen

The TH-A line:

For the control of high or low temperature coefficient heating elements with up to 240kW power

ThyroA series is a complete line of single phase, three phase economy and true three phase power controllers. Load control can be made on voltage and current power. Units include self and load circuit monitoring functions. Two different operating modes are available: Full wave (TAKT) and Half wave (QTM) switching.

TH-A line Features:

• Universal: The ThyroA line inclues the A and AX models suitable for all electrical heating applications ranging from up to 240kW. The start-up procedures, the control and monitoring functions, the configuration and the parameters setting are common for all the single phase and three phase models.
• Versatile: Many models are a great solution for low temperature coefficient heating elements with direct connection and for transformer connected loads.
• Reliable: All models up to 170A are oversized to allow natural ventilation cooling which requires no additional cooling fans.
• Diagnostic Functions: LED status indicators signal if the power controller is powered, operating properly, or if there are device errors or load programs.
• Open Communications: Each ThyroS can be equipped with Modbus RTU, Profibus DP, or CANopen communications.

The ThyroA line inclues the A and AX models suitable for all electrical heating applications ranging from up to 240kW. The start-up procedures, the control and monitoring functions, the configuration and the parameters setting are common for all the single phase and three phase models.

The TH-P line:

For control of high or low temperature coefficient heating elements with up to 2.8 MW power

ThyroP is a complete line of single phase, three phase economy and three phase power controllers. Load control can be made on voltage, current or power. Total or partial load breaks are detected for both low or high temperature coefficient heating elements. MOSI operating mode is also provided which is dedicated to "Super KANTHAL" elements.

Multiple load applications can use synchronized power controllers to minimize power load peaks when working in the full wave mode.

TH-P configuration can be carried out with simple PC configuration software or the integrated data display options.

TH-P Line Features:

• High performance: ThyroP is controlled by a 32 bit, 40 MHz, RISC microprocessor. All the operating modes, control and monitoring functions are integrated into the unit. Flexibility allows the Thyro-P line to be adapted to fit the user's requirements for any electrical heating application.
• Enhanced: The ThyroP line can be integrated in complex systems through the several serial ports that can be integrated in the unit. Integrated communications allow the user to configure, access all operating parameters, and view diagnostic information.
• Safe: All ThyroP models can be equipped with a removable control and display module that allows the user to verify the configuration, the parameters and to obtain rapid diagnostic answers.

The ThyroA line inclues the A and AX models suitable for all electrical heating applications ranging from up to 240kW. The start-up procedures, the control and monitoring functions, the configuration and the parameters setting are common for all the single phase and three phase models.
