Furman PS-8R: Eight Outlet Power Conditioner / Sequencer
FURMAN PS-8R: EIGHT OUTLET POWER CONDITIONER
/ SEQUENCER
The Furman PS-8R 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.
FURMAN PS-8R 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

Using the Furman PS-8R 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 Furman PS-8R 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 outlets may be substituted
at an additional cost.
The Furman PS-8R 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 Furman PS-8R 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.
