Thyristors power controller REVO TH

SCRburstdigital

Compact power controller with modular multi-zone SCR The power controllers REVO TH are one of the latest born into the REVO family. Despite the formidable compactness, inside there are three independent SCR power units , which thanks to thyristor abundantly oversized in their junctions, they can manage currents up to 90A with a maximum voltage of 600V. Using Modbus and/or the more common fieldbus, multiple units can be connected to each other and therefore the ideal application area is the control of heating elements on multiple zones such as the simultaneous control of multiple IR lamps. Other application sectors can be for example: Multizone ovens Machines for plastics (extruders and extrusion lines, extrusion heads and hot runner mold control units) Packaging machines Ovens with long, medium and short wave IR lamp REVO TH integrates THREE independent power control zones in a single product, and includes: Three independent single-phase thyristor power controllers Fixed high-speed fuses Current transformers Control mode V – I – V2 – I2 – P Input signal in digital mode, no connection jumper inside Firing modes: single cycle, half cycle, burst firing, phase angle, delayed trigger, different types of adjustable ramps Two analog inputs Two digital inputs Load and SCR diagnostics Current limit function Alarm outputs 3 independent power controllers in one compact product Max voltage 480V up to 90A Thyristor unit with high I2T Synchronization circuit Integrated extra fast fuses Digital input and relay output HB alarm High precision current transducer Monitoring of RMS voltage, current and power Communication: RS485 Modbus Reduction of cabling and space used
