PAYNE Engineering
Silicon Control Rectifiers
SCR's: Precise proportional control of resistance heating loads. SCR's provide reliable voltage control solutions for a wide varitity of heating applications.

Constant resistance heating loads can be controlled to tighter tolerance
High inrush heating loads can be brought on line slowly with a "soft start" or ramp up to voltage.

Payne offers features that make SCR's reliable for today's manufacturing enviroment.

  • Large Specially engineered Heat sinks allow higher temperature tolerance.
  • Surge Protection: "Vbo Clamping" protects semiconductors against transient voltages regardless of PIV ratings and without MOVs.
  • Short Circuit Protection: factory-tested sub-cycle, "2 millisecond" current-limiting fuses protect the power semiconductors against short circuit damage.
    • Advantages:
  • Millions of Cycles
  • No electromechanical Noise
  • No moving parts
  • Quite
  • protection from chemicals and dust.
  • High resistance to shock and vibration.
  • No Arcing Contacts
    • Dis-advantages:
  • Contact voltage drop "1 to 1.6 volts"
  • Heat sensitive 50° C
  • Heat producing
  • Tolerance to voltage spikes.
    • Quanity:
