Eaton H-Max Series FR7 variable frequency drives (VFDs) are ideal for controlling the speed & torque of an electric motor in a variety of industrial & commercial applications in fans, pumps & conveyors. They match the desired output by adjusting the supplied electrical power's frequency. These VFDs have an FR7 frame size and multiple control modes for voltage, current & sensorless vector control. Their frame door is mounted with a graphic display & keypad for easily controlling the frequency. The H-Max Series VFDs also lower operating costs by reducing energy consumption and improving process control. Read Less
Variable Frequency Drives (VFDs) work by changing the incoming alternating current (AC) into direct current (DC) and then converting the DC back into AC power at a different frequency.
The frequency of the AC power can be varied by adjusting the switching rate of a connected inverter.
Increasing the frequency of the VFD increases the speed of the motor and decreasing the frequency reduces the speed of the motor.
Features
Eaton H-Max Series variable frequency drives have a compact design for easy installation & user-friendly operation.
These units have numerous advanced control & protection functions like adjustable motor overload / short-circuit protection and programmable digital inputs & outputs.
Their removable entry panels (top & bottom) & easily accessible terminals allow quick connections with the equipment.
These VFDs further feature a DC link choke for reducing electrical noise caused by harmonic distortions.
They can be used for remote control & monitoring operations using their digital communication ports & A-type software. They can easily control the bypass circuit using a keypad, digital input, BMS communications or in-fault conditions.
IntelliDisconnect NEMA Type 3R or IntelliPass NEMA Type 3R enclosure of these units protect them from damage.
Selected models have a space heater with transformers and pilot lights for easy, controlled & smart operation.
