KBVF 4G – NEMA 4X / IP66

Hybrid AC Drives Designed and Customised for PMAC Motors

Our 4th Generation (4G) KBVF Hybrid AC Drives now feature IP66 enclosures suitable for both

indoor and outdoor use. We’ve designed these drives to provide optimum control of with

permanent magnet AC (PMAC) motors, sometimes referred to as either brushless permanent

magnet (BPM) motors or permanent magnet synchronous (PMSM) motors.

The easy-to-install KBVF 4G Hybrid AC Drives are customised to suit requirements for 0.7 – 2.2

kW PMAC motors. Since we typically pre-tune these drives for customer applications, they offer

the convenience of out-of-the-box use.

Common applications for these drives include:

• Agricultural ventilation

• Commercial & Industrial fans and exhausts

• HVAC

• Pumps

• Appliances

KBVF Hybrid Drive – Chassis / IP20

The KBVF Series of Adjustable Frequency Drives consist of sixteen inverter models rated for 

0.07 to 3.7 kW motors. These chassis / IP20 drives are ideal for OEM applications where digital

programming and displays are not required. Hybrid drives are digital drives with an analogue

interface.

Options: SIVFR Signal Isolator and Run Fault Relay (Standard on 460 Vac models), DIVF Modbus

Serial Communication Module, Class “A” or “B” (CE) RFI Filter, DBVF Dynamic Brake Module,

Multi-Speed Board.

KBVF 4G – Chassis / IP20

High-Performance Drives for PMSM Motors

The KBVF 4G (4th generation) drive adds robust PMSM control while keeping its simple and

ready-to-use out-of-the-box interface.

The KBVF 4GChassis / IP20 offers drive solutions for from 0.07 to 3.7 kW in an IP20 package.

AC drives for Commercial Appliances and Machine Integration

KBVF drives are ideal for mounting in appliances, machines and control panels where

digital programming and displays are not required. Ready to use out of the box

customisation is available to meet your specific application needs. Custom KBVF drives

provide the exact drive you need without any unnecessary extras.

KBVF AC drives provide variable speed for 3Ø AC Induction motors from 0.07 to 3.7 kW.

For OEM applications, custom drives are also available for Brushless DC, PMSM, PSC,

and Shaded Pole motors. They are available in 115. 208/230. and 380/460 Vac – 50/60 Hz

with 1Ø and 3Ø input, with optional GFCI / RCD compatible software.

All KBVF AC Drives contain Sensorless Flux Vector Compensation with Static-Auto-Tune.

This provides excellent speed regulation from zero to full load over a wide frequency range.

These drives provide auto energy savings at light loads and smooth motor torque operation.

A variety of optional accessories are also available to meet the most demanding applications.

Unidrive M400

Fast set-up and diagnostics with plain text display, integrated PLC and safety inputs

Unidrive M400 minimises downtime with an intuitive LCD keypad offering a real-text, multi

language display for rapid set-up and clear diagnostic help. The integrated PLC can execute a

substantial range of sequencing and logic programs. Coupled with an impressive I/O count

complete with two STO inputs and an SI interface for a fieldbus option or extended I/O, this

feature set ensures Unidrive M400’s flexible integration with any system.
