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
