Thyro-A power controllers are thus excellently suited for application in numerous fields within the scope of process engineering technology, for example:
• Ovens (industrial, diffusion, drying)
• Glass processing (plate glass equipment, feeders, finishing equipment, fiber glass)
• Plant equipment (extruders, plastic presses)
• Chemical industry (pipe trace heaters, pre-heating equipment),
• Automotive industry (paint drying equipment),
• Printing machines (IR drying),
• Packaging industry (shrink tunnels).
Key Features
Besides free-from-wear operations and high perform this product series offers the following features:
• Simple handling requiring little space
• Rated voltages up to 500V
• Rated currents up to 350A
• Single, dual, and three-phase versions (Dual-phase version for three-phase load without deploying the neutral conductor in a cost-saving three-phase circuit)
• Integrated semi-conductor fuses
• LED status indicators Automation Level
• Series-design system interface for connection to an optimal bus module (Profibus DPV1, Modbus RTU, DeviceNet, CANopen,...) for the processing of set points and actual values, as well as for status reports
• Interface option for connection to PC software Thyro-Tool Family
• Safe separation of control and power units Analog Controlling
• Analog set point between 0..10V / 0..20mA
• Control characteristic is adjustable within this interval
• Voltage range at the dual point controller: OFF = 0..3V, ON = 3..24V
Load Side
• High resistance against short-circuit currents and blocking voltage accommodated by the power semi- conductors
• Designed for ohmic load, as well as for inductive mixed load
• Fit for transformer-type load due to an integrated soft-start function, phase-angle firing of the first half-wave and channel separation
