A.C. SEQUENCED POWER
DISTRO, 120 AMP
MODEL ASD-120
FEATURES
● 120 amp total load
● Six 20 amp, 120 volt circuits, each with a status indicators
● Four power input busses accommodate 120V/240V single
phase, or 208V three phase voltages
● Six 20A duplex outlets on rear panel
● Outlets are powered up and down in sequence
● Three position switch allows each circuit to be part of the
sequence, or to be switched on/off independently
● Sequence On/Off can be initiated locally, or remotely
using low voltage control wires
● Six low level relays provide contact closure (or opening) to
control and sequence other units, such as additional
ASD-120’s, PowerPorts, MiniPorts, PowerLinks, PS-8R,
PS-PRO, and other devices
● Varistor spike and surge protection
● Front panel key switch for security
● Compact two rack space package
● Most economical product of its type
The ASD-120 allows you to power up its six circuits in a
sequenced fashion. The sequence is reversed for power down.
The overall delay interval is user-adjustable internally.
In any large system whose components present an inductive
load to the AC line (including power amplifiers, power supplies
and electric motors), sequenced power can avoid excessive
inrush currents that can cause circuit breakers to falsely trip.
Sequenced power is needed whenever various kinds of
equipment must be powered up or down at different times. Also,
sequenced power is often necessary to allow turn-on transients
from low level preamplifiers and processors to settle down before
any power amps or powered speakers are turned on. This is
because simultaneous powering can result in a loud, annoying,
and potentially destructive “pop” reaching the speakers.
The user has complete control of each of the ASD-120’s
outputs. A three-position front panel switch for each control output
allows it to be included in the sequence, or to be overridden.
Indicator LED’s show when each output is “on.”
While the ASD-120 is ideal for controlling MiniPorts, it can
also control PowerLinks, PowerPorts, PS-PRO or PS-8R Power
Sequencers, or any other devices that need to be switched when
a particular time delay has elapsed. An ASD-120 can also control
additional ASD-120’s, providing complete power sequencing
control for even the largest systems.
DESCRIPTION
The ASD-120 AC Sequenced Power Distro is an extremely
compact, low cost rackmount power distribution system that is
ideal for PA systems, touring musical and theatrical acts, mobile
recording facilities, on-location film and video shoots — or any
situation where AC power must be distributed to multiple circuits.
Use of an ASD-120 is cost-effective, both in terms of the
convenience it offers and the elimination of bulky and expensive
parallel feeds and related connectors.
The ASD-120 can handle up to 120 amps of incoming power,
distributing it to six 20 amp, 120V circuits. Each circuit has a front
panel status indicator that lights up when it is turned on, and a 20
amp duplex outlet on the rear panel.
The ASD-120’s design incorporates four voltage input busses,
allowing wiring for 120V/240V single phase, or 208V three phase
voltages. A strain relief clamp is provided that can accommodate

a cable or wire bundle up to 1.5 inches in diameter. Cable
termination is a simple process of breaking out and stripping the
individual conductors and connecting them with set screws, and
then tightening the strain relief clamp. Complete instructions
accompanying the unit detail the process of selecting and
terminating the supply cable.
The ASD-120 provides basic spike and surge suppression,
with metal oxide varistors (MOV’s) connected between the hot
and neutral conductors of each circuit. The MOV’s respond to
line-coupled spikes in less than a nanosecond, clamping transient
voltages to safe levels of 200V peak or less.
provided for each output, allowing it to be set ON or OFF locally,
overriding the sequence. Each output shall have a front panel
indicator readable at 20 feet showing the circuit ON status. Circuit
breakers rated at 20 amps shall be provided for each circuit.
Sequencing shall be provided for each of the six circuits. Overall
sequence time shall be internally adjustable from 1.2 to 60
seconds. Each circuit shall have a front panel indicator clearly
readable at a 20 foot distance showing the circuit ON status.
Architects and Engineers Specifications
Each circuit shall include a protective device capable
of clamping line to neutral spikes to no more than 200V peak.
Response time shall not exceed 1 nanosecond. The devices
shall absorb a surge current of up to 6500 amperes for 10
microseconds without damage.
The Power Distro shall mount in a standard 19" rack, and
shall occupy two units (3 1/2") of rack space.
The unit shall be the Furman ASD-120 Sequenced Power
Distro.
It shall employ a four-buss structure (plus chassis ground)
which can be re-configured as needed using an ordinary
screwdriver. Buss input connections shall accommodate wires
from 2 AWG through 8 AWG. Buss output connections shall be
via repositionable Fast-On connectors. Buss construction shall be
of solid copper capable of handling at least 125 amps. A secure
cable clamp shall be provided which can accommodate an input
cable up to 1.5 inches in diameter.
There shall be six output circuits on the rear panel, with a 20
amp duplex outlet for each. Outlets shall be turned on and off by
heavy duty 25 amp relays. A three position switch shall be
