TERSEDIA INVERTER 3PHASE/SINGLE PHASE
Also on this page:
Frequency inverter drives are a key
component of Mitsubishi Electric's factory automation systems. More than 30
years on and with over 14 million units sold worldwide, Mitsubishi Electric is
still continually contributing innovations to variable-speed drive technology.
The latest 64-bit RISC processors, advanced software models and the latest
power electronics make today's variable-speed drive solutions from Mitsubishi
Electric both powerful and easy to use. Mitsubishi Electric delivers
innovative, open, flexible and reliable drive solutions geared to the special
needs of individual markets and customers.
Mitsubishi frequency inverters
satisfy all the standards and specifications of the European Union's 2006/95/EC
directive on low-voltage equipment and the 2006/42/EG machinery directive. All
products have a CE certificate subject to 89/336/EEC, and also UL, cUL and DNV
certificates and the certification for the Russian market. All important
protective functions are included as standard equipment, and all Mitsubishi
frequency inverters conform to both the ISO 9001 quality standard and the ISO
14001 environment standard.
Energy
saving and regenerating frequency inverters
Mitsubishi inverters are real energy
savers achieving maximum drive capacity utilisation with minimum power
consumption. Flux optimisation ensures that the connected motor only gets
exactly the amount of magnetic flux required for optimum efficiency. This is
particularly important at low speeds as motors are normally using a
voltage/frequency control system. SLV Vector Control with Online Auto tuning
and automatic slip compensation, V/f control with a fully-programmable
characteristic and Mitsubishi Electric's advanced OEC (Optimium Excitation
Control) technology all help to make these frequency inverters masters of
energy conservation. They can achieve maximum power savings of up to 60%
compared to conventional mains operation, thus minimising system operating
costs.
The FR-A741’s regenerative
braking system makes it much more efficient than conventional drive systems,
giving it the potential for significant energy savings. They are particularly
well suited for tasks involving frequent cyclical acceleration and deceleration
and in all applications where braking resistors are normally used. The
combination of the integrated AC reactor and no need for an external braking
unit eliminate a large amount of additional wiring. These inverters need up to
60 % less main circuit wiring and occupy up to 40 % less space than
conventional solutions, depending on the output capacity.
The FR-F740 frequency
inverter drives from Mitsubishi Electric are designed for the special needs of
pumps and fans. These inverters can significantly enhance the energy balance of
pump and fan applications - particularly in the low-speed range and in low-load
operation, where energy savings of up to 60% can be achieved. Additional
savings are made possible by Mitsubishi Electric's innovative OEC (Optimum
Excitation Control) technology. This system ensures that the optimum magnetic
flux is always applied to the motor, thus reducing losses. The result is
maximum utilisation of motor capacity at maximum efficiency.
Product
range
The series covers a very broad
output range from 0.1kW all the way up to 630kW. Lines include the smallest
FR-D700 series for simple applications, the medium-range FR-E700 series and the
high-performance FR-A700 series. The product range is complemented by the
FR-F740 series that is optimised for the special requirements of pump and fan
applications in the HVAC sector.
All frequency inverters feature
simple operation and configuration and optimised control and data management
facilities. The integrated control terminals, the one-touch digital dial and
the multi-language control panel with copy function provide
instantly-comprehensible information on current drive status and clear error
message displays.
Networked systems are very easy to
configure thanks to support for standard open network bus systems including
Profibus/DP, DeviceNet, CC-Link, CANopen and LonWorks. Serial RS-422 and RS-485
interfaces and the optional USB port enable multidrop applications with up to
32 stations and connection of the latest PC and process visualisation systems.
IMS
