Today's
innovative building services impose a wide variety of demands on drive systems.
As a result more planners are now looking for open, flexible and fully-scaleable
drives. Additional requirements include user-friendliness, network support and,
of course, maximum reliability - particularly in heating, ventilation and air-conditioning
(HVAC) applications. The drives must also be economical to use, combining minimum
operating costs and maximum energy savings. The frequency inverters of
the FR-F700 series are a modern and intelligent drive solution that can easily
be integrated into complex modern building services automation systems. The FR-F700
frequency inverter drives are particularly well suited for driving pumps and fans
and for applications with reduced overloads, such as air-conditioning systems
in building services and industry, ventilation and air extractions systems, drains
systems, ground water pumps and heat pumps. In addition to the IP00 and
IP20 protection ratings the inverters in the output range up to 55kW are also
available with an IP54 rating (FR-F 746 series). FR-FSU
- Floor-Standing Unit for FR-F740 frequency inverters Mitsubishi
Electric now offers new housing units for free-standing installation of frequency
inverters outside the switchgear cabinet. The sturdy Floor-Standing Units have
an IP20 protection rating. They are delivered pre-configured and in addition to
the frequency inverter itself they also have space for integration of a DC reactor
or an additional EMC filter. FSUs are available in a variety of sizes to match
the different output capacity models of FR?F740 frequency inverters. It is delivered
with a complete installation kit including screws, cables and terminal block.
