SCR Gate

Feature

Description

  • Analog delay angle command signal (SIG_HI)Users may choose a variety of DC control signal ranges including 0-5V, 0-10V, 4- 20mA, or custom ranges.

  • Soft-Start and Soft-Stop : Upon Soft-start, SCR firing is enabled and the delay angle command ramps from the maximum value to the set point value determined by the SIG_HI command signal. Upon Soft-stop, the delay angle ramps from the set point value to the maximum value after which SCR firing is inhibited.

  • Phase Loss Inhibit : A phase loss circuit instantly inhibits SCR firing if a loss of one or more phases or gross phase imbalance is sensed on the AC line. Firing will soft-start when such fault is cleared.

  • Instant enable and Inhibit: A contact closure(relay, switch, transistor) instantly enables or inhibit SCR firing at the delay angle commensurate with the SIG_HI command Signal.

  • Frequency tracking system : This board has automatic frequency detection circuit. When line frequency had changed, the detection circuit will change internal firing phase.

  • Phase sequence insensitivity : SCR gating is unaffected by main voltage phase sequence.
