-
SCR Power Controller
Electrical modification adding an SCR Power Controller. Features:
- Silicon controlled rectifier power controllers are completely solid state industrial controllers that ensure precise proportioning of electric power to the heating elements
- Oven temperature is maintained smoothly and evenly over the entire temperature range of the unit.
- SCR power controllers minimize maintenance, as there are no moving parts or electrical contacts to wear out.
- Heating element fatigue is reduced since the elements do not cool between releases of electric power.
- Zero voltage firing, including the first one half cycle of voltage, minimizes radio frequency and electromagnetic interference.
- Transient voltage suppressor networks are included, and the units are provided with protective fusing.
-
