INVERTER
/// INVERTER
Mitsubishi Electric’s FR-F 740 series is a
completely new range of fre quency
inverters with truly exceptional power
conservation capabilities. These invert
-
ers are ideal for pumps, ventilation fans
and applications with reduced overload
requirements such as:
Air conditioning systems, e.g. in building
management
앬
Air extraction systems
앬
Fans and blowers
앬
Hydraulics systems
앬
Compressors
앬
Sewage and drains systems
앬
Ground water pumps
앬
Heat pumps
앬
Drive systems with high idling rates
These inver ters 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.
The FR-F746 with its waterproof struc
-
ture IP54 is available with outputs from
0.75 – 55 kW .
All the inverters in the series are designed
for connec tion to 3~ 380 – 480 V/500 V
(50/60 Hz) power supplies.
