Available in a number of packages with current sizes from 3 amps to 800 amps, the CD Automation range of multi-zone power controllers combines precise temperature control with energy saving power optimisation.

Catering for both the simple electrical heat process on packaging machines, through to the more sophisticated short wave infrared paint spraying car production line, we have the perfect solution to your multi-zone, multi-channel power control needs.


  • Save costs with a total solution in a single package – reduces wiring by up to 70% compared to single stacks, cabinet dimensions by up to 80% and a reduction of commissioning times by 20%
  • Cut your energy bills – restrict current peaks by automatically sychronising multiple zones and distributing your power demand across your whole system
  • See what’s happening fast – smart diagnostic functions immediately detects and localizes errors in the load circuit with the support of the extensive TIA diagnostics system
  • Simple connection to your system – connect seamlessly with your management software with the most popular Fieldbus systems


  • Designed specifically for normal resistance heating elements and short/medium wave infrared lamps, the REVO-PN & PC can control both multiple single and 3 phase loads.
  • Multiple Transformer & inductive plus variable resistance loads are handled withthe REVO-TH power unit.
  • Firing modes include Simple Burst Firing and Half & Single Cycle Firing plus Dynamic Burst Firing, Half Cycle and Single Cycle with Sychronisation, Delayed Triggering & Phase Angle with or without Soft Start
  • Fieldbus Comms options include Modbus TCP, Modbus RTU, Profinet, Profibus & Ethernet IP


Product datasheets and manuals can be found under the Documents & Manuals tab above.

Suitable for Load Types

  • Normal Resistance
  • Short, Medium and Long Wave Infrared Lamps
  • Inductive (Transformer Primary)
  • Cold resistance and SiC element load types (single phase only)

REVO-C Thyristor Power Controller Overview

No problem, our qualified engineers are here ready to answer your call, fax or email. If you like to browse the information first, we have all product information on-line plus useful calculation & product selection tools to help you select the right product. And all accessible 24/7 without the need for passwords or any form filling.

If the item is not in stock then we will normally guarantee the goods delivered within 7 days if required. This may depend on the quantity and size (if thyristors) but for quantities of 20 or less, then this should never be a problem.

We’ve made this as easy and accessible as we can. As the Internet is open 24/7 we have loaded as much relevant product data onto our web site and in a clear concise manner, so you don’t waste unnecessary time. Data includes quick-look guides for wiring / dimensions / start-up, product features & comparisons, selection tools, product data sheets, full installation & operating manuals plus press releases & application notes.

We know from experience that next year the order of 2 may be 500. Our relationship with our clients, big or small, is never taken lightly. See our Company Mission Statement, it’s who we are.

We understand that speed is important in business and as long as you accept that the accuracy of the quote is proportional to the amount of data given, we’ll provide a quote any which way you like (typically over the tel, via fax or email, or in person).

We do not differentiate a telephone enquiry to an email enquiry. The same level of importance is applied to both. You will always receive an email to confirm receipt and a guaranteed personal reply within 20 minutes (within normal working hours).

We offer delivery based on the urgency and size/weight of the goods that match your expectations. From just £6.50 for next day courier, we can offer before 9am, before 12, anytime next day plus two day courier services within the UK.

We only charge the true carriage cost plus any additional package material to get it safely to you. We do not believe its right to charge you any additional admin or labour packing costs, anymore than if we charged you for answering the telephone. And it’s always our responsibility until you sign & receive the goods.

If it’s legal then we can accept it. We operate favourable credit accounts, payment by credit card via the web site or over the phone, cheque or cash payments, in Sterling or Euros.

Our products have proven built-in reliability so you should not need our terrific service. However, for ALL breakdown situations we guarantee a 48 hour* dispatch of a new replacement unit where necessary (*excluding transit time).
