KV2 Audio ESP2000 - Manual (Page 6)

NOTE: It is recommended that the
voltage supply be within the rated
voltage window. This ensures that
AC voltage variations from the service entry -
or peak voltage drops due to cable runs - do
not cause the amplifier to cycle on and off or
cause damage to the power supply.
NOTE: For best performance, the AC
cable voltage drop should not exceed
10 volts, or 10 percent at 115 volts
and 5 percent at 230 or 250 volts.
Make sure that even with the AC voltage drop,
the AC voltage always stays within recommended
operating ranges. The minimum electrical service
amperage required by an ESP2000 amplifier is
the sum of each amplifiers maximum continu-
ous rms current. An additional 50 percent above
that amperage is recommended to prevent peak
voltage drops at the service entry.
The Power Connector
The ESP2000 requires grounded outlets. It is
very important that the amplifiers AC supply
be properly grounded in order to operate
safely and properly. Use the PowerCon AC
cable-wiring diagram overleaf to create inter-
national or special-purpose power connectors:
Current Requirements
Each of the ESP2000’s power supply inputs
require approximately 20 Amps max at 115V AC
for proper operation. This means that both of the
ESP2000’s power supplies must be powered from
an individual 20 A breaker when running in 115V
mode.
When operating in 230 V mode each of the ESP
2000’s power supply inputs requires approximate-
ly 10 Amps max. This allows a complete ESP2000
to be powered from one 20 A breaker at at 230
V.
The ESP2000 presents a dynamic load to the
AC mains, which causes the amount of current to
fluctuate depending on quiet or loud operating
levels. Since different cables and circuit breakers
heat up at varying rates, it is essential to under-
stand the types of current ratings and how they
correspond to circuit breaker and cable specifica-
tions.
The maximum long-term continuous current is the
maximum rms current during a period of at least
ten seconds. It is used to calculate the tempera-
ture rise in cables in order to select a cable size and
gauge that conforms to electrical code standards.
It is also used to select the rating for slow-reacting
thermal breakers.
