-
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.
