MITSUBISHI ELECTRIC
FR-F 740 EC/E1
SYSTEM DESCRIPTION
Mitsubishi Electric’s FR-F 740 series is a
completely new range of frequency invert
-
ers with truly exceptional power conserva
-
tion capabilities. These inverters are ideal
for pumps, ventilation fans and applica
-
tions with reduced overload requirements
such as:
Air conditioning systems, e.g. in building
management
Ȝ
Air extraction systems
Ȝ
Fans and blowers
Ȝ
Hydraulics systems
Ȝ
Compressors
Ȝ
Sewage and drains systems
Ȝ
Ground water pumps
Ȝ
Heat pumps
Ȝ
Drive systems with high idling rates
These inverters are very user-friendly and
they are available with output ratings
matched to users’ real needs.
The FR-F 740 is available in versions with
outputs from 0.75 – 640 kW. All the inver
-
ters in the series are designed for connecti
-
on to 3~ 380–480 V/500 V (50/60Hz) power
supplies.
The output frequency range is 0.5 – 400 Hz.
Proven Technology with Advanced New Capabilities
Innovative performance
optimisation
The drive performance of the FR-F 740
series is optimised for the special needs of
fan and pump applications. Drives in appli
-
cations like these are characterised by a
load torque curve that increases by the
square of the motor speed (variable curve).
Of course, these frequency inverters can
also be used for standard applications with
constant load curves and a maximum over
-
load of 150%.
