Mitsubishi Inverter FR-F700PJ Series : FR-F740PJ-3.7K

FR-F700PJ Series
Features

• Suitable for both the general-purpose motor and the IPM motor

The series can drive both a general-purpose motor and IPM motor. Switching between the two motor controls is simple--just a single parameter setting. Initially, a general purpose motor could be used, then upgraded to an IPM motor without switching this inverter, leading to lower cost of equipment.

• Environmentally Friendly 

Power factor improving DC reactor, common mode choke (line noise filter), capacitive filter (radio noise filter) are all essential for air conditioning applications, and all of these are included in the conditioning applications and all of these are included in the Filter pack. The inverter with Filter pack (FR-F7[]0PJ-[]F) is also available The wiring with different options is no longer required.

Less wiring and smaller space is required when Filter pack also enables compliance with the harmonic suppression guideline, the architectural standard specifications (electrical installation), and the architectural standard specifications (machinery installation) (2010 revisions) in japan 

• Easy-to-use

The following functions provide the ideal operation for fans and pumps (PID control, Optimum excitation control, regeneration avoidance, and automatic restart after instantaneous power failure)

• Improved reliability and easy maintenance 

Spring clamp terminals provide high reliability and easy wiring. The lives of the cooling fan and capacitor have been extended. Using the self-diagnosis function, the component life warning can be monitored to prevent malfunction.
