Product Description

5.5KW 220V Variable Frequency Drive

This VFD converter can be used for constant-torque loads ( air compressors, HVAC units, and other hard-start kits.) and variable-torque loads (pumps, fans, etc.). It can also be used as a motor speed controller and phase converter. This VFD features 1- or 3-phase input and 3-phase output, and you can adjust the speed as needed.

Adopting sine wave PWN, this inverter’s control system features high torque drive, high-accuracy wide-range speed regulation that has 8-stage / 16-stage speed control, program operation, four settings of acceleration/deceleration time, and more.

NOTE:

1. The VFD can’t be used as a power source for other equipment, or to drive a motor with a supply voltage lower than 80V.

2. Do not connect the VFD’s output terminals with capacitive loads.

3. Choose a VFD with a larger power output when operating heavy equipment like the crane and compressor, e.g.,a 5.5 Kw motor should be connected to a 7.5 Kw VFD.

4. If a generator is used to power the VFD, ensure that the generator’s output voltage level is within +/-15%.

Package Includes

1* 5.5KW VFD
1* Operation Manual
1* Extension Wire

Powerful Cooling Fan

The fan adopts an independent air duct design for efficient heat dissipation, ensuring that the internal temperature of the inverter is suitable for long-term stable operation.

Braking Resistance

The VFD can be connected with an external braking resistor (not included), which can consume the energy generated by the motor with an energy feedback device, such as the motor of lifting equipment or centrifugal equipment, and allows for fast braking of the motor, e.g., enabling the spindle of an engraving machine with a peed of 24,000 rpm/min stop within 0.5s-2s.)

High-Quality Material

The ABS VFD chassis is flame retardant, anti-impact, and corrosion-free. It performs well in protecting the breaker from tripping and has good anti-jamming performance of temperature, humidity, and dust.

RS-485 Communication Function

With RS-485, a single controller, e.g. a PLC or DCS, can control multiple inverters. Also, this VFD’s start, stop, frequency setting, status monitoring and feedback, etc., are all controllable through RS-485.

Dual-Chip Design

The motor program of the VFD frequency converter is independent from the control program, which features redundant computation, strong anti-interference ability, high-speed running, and stable operation.

Multiple Protection
