1011:
"Controlling Molybdem Disilicide Heating Elements with Zero-Crossing Power Controls"
Historically, Molybdenum Disilicide (Moly) heating elements have been controlled with either contactors or Phase-Fired SCR Power Controllers. Due to its resistance being nearly zero when cold, a Phase-Fired SCR can regulate itís output voltage into zero ohms avoiding extremely high surge currents normally associated with energizing Moly loads.
