Multi-Zone Power Controllers

Simplify Your Electrical Heating Architecture with One Intelligent Multiloop System.

If your cabinets are full of single-zone controllers, SSRs and fuses, you’re wasting wiring, fighting power peaks and losing time on faults. The REVO Multiloop Power Network gives you one coordinated system to control 2–24 zones per node, optimise energy peaks and stabilise temperature across every heater and IR lamp.

✔ Stop juggling dozens of standalone controllers for each heating zone

✔ Eliminate power peaks and flicker caused by uncoordinated firing

✔ Locate heater and SSR faults in minutes, not hours inside a hot cabinet

Multi-Zone Power Controllers

The Hidden Cost of
“One Controller per Zone”

On paper, your current architecture works: a temperature controller and power unit for each zone, wired back to the PLC. In reality, it’s creating problems you feel every day.

Panels full of hardware and wiring

Every new zone adds a controller, SSR, fuse, terminals and documentation. The result is a cabinet that’s crowded, complex and difficult to maintain.

  • More components to specify, wire, test and document.
  • More sources of failure and more time spent troubleshooting.

No coordination between zones

Each zone fires “when it needs to”, with no understanding of what the other zones are doing. That means unpredictable current peaks, flicker and harmonic distortion.

  • Voltage dips and visible flicker when multiple zones turn on together.
  • Hot cables and stressed transformers due to uneven loading.

Painful fault-finding & energy pressure

A single failed heater, SSR or fuse can take hours to locate. Meanwhile, energy teams demand better power factor and controlled peak demand.

  • Time spent inside hot cabinets chasing a single fault.
  • Energy costs and penalties that your current setup can’t easily address.
From your perspective
“You’re not just assembling parts, you’re accountable for uptime.”

As a senior automation or electrical engineer, your job isn’t just to choose hardware from a catalogue. You’re responsible for keeping production running, avoiding penalties and making projects repeatable.

Every time you’re back in the cabinet hunting for blown fuses or chasing a nuisance power issue, it’s time you’re not spending on optimisation, innovation and delivering the next project.

What This Costs You (beyond the hardware price).

Extra components and uncoordinated zones rarely show up on the initial quote, but you see their impact over months and years of operation.

Engineering overload

Cabinets full of single-loop stacks mean more time spent designing, wiring and documenting. Every new line feels like starting from scratch.
  • Longer design cycles and larger BOMs.
  • Higher chance of wiring errors and commissioning delays.

Unplanned downtime & scrap

When faults are hard to locate, production slows or stops. Meanwhile, temperature drift and uneven heating increase scrap and rework.
  • Zones drift from setpoint.
  • Inconsistent IR heating.
  • More scrap and rework.

Power quality penalties

Uncoordinated firing creates current spikes, distortion and poor power factor, the exact behaviour your energy supplier dislikes.
  • Higher peak demand and potential contractual penalties.
  • Shortened lifetime of transformers, cables and switchgear.

REVO PN, REVO PC & REVO DPU - The Core of the REVO Multiloop System

For modern electric heating applications, REVO provides a scalable, intelligent control system. REVO PN and REVO PC manage normal resistive heating loads, while REVO DPU adds the capability to control not only normal resistance heaters, but also variable resistance loads (such as silicon carbide) and transformer-fed loads.

REVO PN – Multichannel SCR Power Controller
(Resistive Loads)

REVO PN is designed for multi-zone electric heating applications where clean control, stable power delivery and compact wiring are essential.
  • Handles up to 24 × 1-phase zones.
  • Supports up to 8 × 3-phase loads.
  • Maximum current: 25A per zone.
  • Ideal for normal resistive heaters and IR lamps.
  • Integrated diagnostics and Dynamic Burst Firing.

REVO PC – High-Current Multichannel Controller
(Resistive Loads)

REVO PC controls external power units such as REVO S, REVO Sx or REVO PB, allowing you to scale easily into higher currents while maintaining full multiloop coordination.
  • Controls up to 24 channels.
  • Supports up to 8 × 3-phase loads.
  • Maximum current: 800A per zone (using external power modules).
  • Perfect for high-current resistive heaters and multi-zone process lines.

REVO DPU – Synchronisation for Complex Load Types

REVO DPU is the advanced control layer for complex or heavy-duty heating systems. It manages power quality, peak demand, harmonics and firing strategy, while coordinating up to 24 external SCRs.
  • Controls up to 24 single or three-phase controllers
    (REVO C or REVEX).
  • Maximum load capability: up to 2100A.
  • Normal resistive loads: precise power control with soft-start and synchronised burst.
  • Variable resistance loads ideal for SiC and other resistance-changing heaters.
  • Transformer-fed loads: phase-angle start with current limit + automatic transition to burst firing.

Smart Power, Lower Energy Costs

Power optimisation on REVO PC is designed for multi-zone heating systems where many loads operate simultaneously. Using synchronised Dynamic Burst Firing, REVO PC coordinates all zones so total line current remains as constant as possible, rather than allowing random current peaks. This intelligent distribution of power reduces unnecessary losses, lowers peak demand and ensures only the real power required by the process is drawn from the supply.

The result is significantly improved power quality: power factor is maintained close to unity, harmonic components are minimised and voltage disturbances such as flicker and dips are greatly reduced. For the customer, this means lower energy costs, reduced stress on cables and transformers, improved network stability and reliable operation without the need for external power-factor correction or harmonic filtering.

When to Choose PN, PC or DPU

Reduces compliance costs and shortens project approvals—ideal for OEMs exporting machinery.
  • REVO PN → Standard resistive heaters, multi-zone low-current control (up to 25A).
  • REVO PC → Higher-current resistive heaters requiring up to 800A per channel.
  • REVO DPU → Complex loads: variable resistance, transformers, heavy-duty IR or SiC heaters.

From Complex Cabinets to a Clean, Optimised Multiloop System

The real value of REVO isn’t the hardware list. It’s how your day-to-day work, and your plant, feel after the change.
Before REVO:
  • Cabinets packed with single-zone controllers, SSRs and fuses.
  • Long commissioning times and long wiring diagrams.
  • Flicker, voltage dips and grid disturbances.
  • Heater faults that take hours to locate.
  • Growing pressure from management on energy and power factor.
After REVO:
  • Up to 70% fewer components and cables thanks to multichannel controllers.
  • 2–24 zones per node, all visible and configurable from a single point.
  • Automatic energy peak management and improved power factor.
  • Fast diagnostics, heater and SSR issues pinpointed quickly.
  • A scalable architecture you can replicate across future lines.

Example: Thermoforming Line with IR Ovens

Your next thermoforming line goes from design to commissioning with fewer part numbers, fewer drawings and fewer wiring errors. The PLC sees each zone’s temperature and power data from a single communication node. When a heater fails, diagnostics identify the exact channel in seconds.

Your energy team shows a reduction in peak demand and better power factor. Your customer gets more consistent product quality thanks to stable, uniform heating. And you deliver a system that is easier to support and scale across future projects.

Design Your REVO Multiloop Architecture in One Call

You don’t have to redesign your entire plant from scratch. Start with one line, one machine or one problematic group of zones, and we’ll help you map: which loops sit on REVO RT / RT Loop, which zones belong on REVO PN, REVO PC and REVO Sx, where you need REVO DPU, and how REVO PB can document your savings.
