Power Sequencing Albany NY

And in any large system whose components present an inductive load to the AC line (including electric motors, power supplies, and power amplifiers of all kinds), sequenced powering can avoid excessive inrush currents that cause circuit breakers to trip even though the steady-state currents are not excessive in Albany.

POWER SEQUENCING IS NEEDED WHEN various types of electronic equipment must be powered up or down in groups, rather than all simultaneously. In AV systems, sequenced powering is often necessary to allow turn-on transients from low-level amplifiers and processors to settle down before any power amps are turned on, because simultaneous powering would result in a loud, annoying, and potentially destructive pop reaching the speakers.

And in any large system whose components present an inductive load to the AC line (including electric motors, power supplies, and power amplifiers of all kinds), sequenced powering can avoid excessive inrush currents that cause circuit breakers to trip even though the steady-state currents are not excessive.

CHOOSING A POWER SEQUENCER

Any power sequencer for pro AV applications should be rack mountable, manufactured in a heavy duty steel chassis, be rated for at least 15 amps, and offer basic spike/surge suppression and RFI filtering. Other considerations include:

  • Number of outlets and delay groups: Two delay groups may be adequate, but sometimes three are needed. Six outlets is minimum (two for each delay group), and eight is preferred, with two or more unswitched. An unswitched outlet on the front panel is always handy.
  • Adjustable delay intervals: The capability to adjust the delay (internally or externally) allows maximum flexibility.
  • Daisy-chain cap...
