Product Information
Intended Use
An off-line AC power
system for the
emergency operation of
HID, incandescent and
fluorescent emergency
lighting loads that
provides full light
output for 90 minutes of
operation.
FT and 3FT have a 65K amp
inrush current rating.
Sinusoidal output
waveform has <3% THD.
Off-line uninterruptable
system has 2-millisecond
transfer time.
Standard circuit
protection: low-voltage
disconnect, short-circuit
protection, currentlimiting, fused-battery
protection, brownout
protection, input circuit
breaker.
Construction
Free-standing NEMA
Type 1 cabinet.
Microprocessorcontrolled PWM inverter
with IGBT technology
allows for universal
compatibility.
Standard RS232
diagnostic interface on FT
and 3FT.
EAC FT output ratings:
1,500 VA to 16,700 VA.
Single- phase system.
Listings
UL Listed (standard) for
90 minutes of emergency
operation.
EAC 3FT output ratings:
4,800 VA to 50,000 VA.
Three-phase system.
Meets NFPA 101, OSHA,
NEC and City of Chicago
Codes.
EAC FTT output ranges:
500 VA to 2000 VA.
Single-phase system.
Field upgradable (500 VA
system).
Example: EAC 3FT 6000 208 FSP
Lead times will vary depending on options selected. Consult with your sales representative.
