Multi-channel Thyristor (SCR) Power Controllers

Multizone power controllers for complex control tasks. Models with built in temperature control and others that minimise harmonics, improve power factorand quality, and optimise power draw by synchronising loads to make power draw as near constant as possible. Feel free to contact us on 03 9720 4522 or sales@practicalcontrol.com.au to discuss your specific needs.

Integrated unit:
The modular system of our units allows to integrate all the components and control functions of the electric heating.

Less overheads
Up to 70% wiring savings, your cabinet become up to 80% less in dimension, reduction of commissioning times (-20%)

Smart diagnostics
The smart diagnostic functions immediately detect and localize errors in the load circuit with the support of the extensive TIA system diagnostics

Easy integration of the heating process
Libraries and examples already available make the heating process easily integrated into the automation system based on Siemens or Rockwell PLC systems

The engineering efficiency with TIA Portal guarantees maximum integration of all components with a shared database.

Integrated load management
The load is evenly distributed on the network as allowed by the specified setpoint values.

REVO RT power controller picture

REVO RT – 3-zone PID combined temperature and power controller up to 90A


The REVO RT is a compact power controller unit, which integrates three closed loop PID temperature controllers, and thyristor (SCR) power controllers.
Each unit manages 3 independent temperature control loops. The unit can be purchased with the diagnostic functions for the load and for the SCRs. In this case there is
a current transformer for each channel.
Each power channel is equipped with extra rapid fuses.
The power inside the unit, current transformer and extra rapid fuses in a single unit save a considerable space inside the panel and time for wiring.
Available in the following currents: 35, 50, 75 and 90A with maximum voltages 480V and 600V.

REVEO TH power controller picture

REVO TH – 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.
Multiple firing modes are available as well as a selection of feedback modes so it can be used on virtually any load.
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.

REVO-PB power controller picture

REVO PB – Three one phase SCR power controller with power optimization algorithm


REVO PB is a multi-channel power unit, specifically designed for multi-zone industrial applications. A basic system consists of a single three-channel module, having the same single-phase connection. Using at least three REVO PB modules for a total of 9 power channels it is possible to balance all three phases. Sophisticated algorithms synchronise loads to minimise and flatten out peak power consumption which minimises peak based tariffs, optimises power factor, minimises hrmonics and generally improves power network quality.
At every channel/zone it is possible to connect a single phase load of maximum 35A / 50A / 75A / 90A with a connection Phase – Phase or Phase – Neutral.
