Linear Step Power Controllers
CCE Series
Linear Step Controllers
Up to 32 stages
Technology
 On large kW custom heaters, a Cristal Controls electronic step power controller offers the full advantages of both the Cristal Controls SCR as well as step controller and can bring maximum energy savings.
In this system, normally recommended for precise temperature control on heaters drawing more than 100 Amps, one SCR heating stage, usually 25% larger than other heating stages, is proportionally controlled with Cristal Controls SCR.
The other heating stages are controlled by the electronic step controller. The SCR stage automatically fills the gaps between step controlled stages, thus providing fully proportional control over the entire heater kW range.
Advantages
- This scheme is far more economical than using SCR controllers to carry the entire heater load, but is entirely equivalent in operation
- Cristal Controlss step controllers range from 2 to 32 steps
