Details
Features * Power-up in three delayed outlet groups * Power-down reverses sequence * Triple-mode varistor spike and surge suppression * RFI filtering with multi-stage EMI/RFI filter * Power Status LED’s indicate which outlets have power * Mains Wiring indicators monitor wiring integrity, show Normal and five kinds of faults * Remote option (model PS-8R) allows turn-on/turn-off at a distance simply by connecting a switch (and LED if desired) * Multiple units may be daisy-chained using PS-REL relay * Three unswitched outlets (one front, two rear) * 15 amp rating with circuit breaker * Three Year limited warranty DescriptionThe Furman PS-8 Power Sequencer is needed whenever various kinds of equipment must be powered up or down in groups, rather than all simultaneously. In audio 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.Using the PS-8 is a simple and inexpensive way to apply and remove power in a controlled, repeatable, foolproof 3-step sequence. It is ideal when large installations must be switched by inexperienced personnel.The PS-8 provides three outlet pairs labeled Delay 1, Delay 2, and Delay 3, that receive power almost immediately, 5 and 10 seconds respectively after the front panel switch is thrown to “ON.” When thrown to “OFF,” the sequence is reversed, with Delay 3 losing power almost immediately, Delay 2 after 5 seconds, and Delay 1 after 10 seconds. The delay intervals are preset at these durations, but may be altered by means of an internal trimpot adjustment. In addition to the delayed outlets, a single front panel outlet and a rear panel pair are unswitched. All rear panel outlets are standard 120V, 15A duplex types; isolated ground “super spec” outlets may be substituted at additional cost.The PS-8 offers all basic power conditioning features besides its sequencing capability. It provides varistor spike and surge protection across all three modes, as well as a sophisticated EMI/RFI filter for blocking radio frequency line noise. Clean, filtered power is provided at all 9 outlets, even the unswitched ones.The PS-8 also assists in analyzing any faults that may occur in the AC mains wiring. Two green and one red neon indicators light in a specific pattern for normal wiring and in different patterns for various faults. When the AC wiring is correct, both green indicators will be lit. If a fault is present, a chart next to the indicators will identify its exact nature.
