View ProductKB Electronics DC drives are designed to control the speed of DC motors in machinery and equipment where adjustable speed, current limit protection and reliable operation are required.
These SCR and PWM-based drives are suited to permanent magnet, shunt wound and universal DC motors and provide speed regulation, current limit protection and accessory support such as plug-in horsepower resistors for matching the drive to a specific motor.
The range includes Vari-Drive style SCR controls and other DC drive formats across common industrial voltage and horsepower requirements, with rugged NEMA 1 and other enclosure options available for different installation environments.
KB Electronics DC drives give Australian OEMs, maintenance teams and industrial buyers a practical way to add variable speed control to permanent magnet, shunt wound and universal DC motor applications. The range spans sub-fractional horsepower through to 5 horsepower and includes SCR Vari-Drive style controls and other DC drive formats housed in rugged NEMA 1 enclosures.
These drives are commonly selected where speed adjustment, current limit protection or compact DC motor control is needed for industrial or OEM equipment. Depending on the model, options are available across 115 and 230 VAC single-phase supply, with armature voltages such as 90 VDC and 180 VDC to suit different motor types.
The best KB Electronics DC drive choice depends on the motor, the available supply and any accessory requirements. In most cases, the starting point is the motor nameplate, the armature voltage and current rating, and the required speed range.
If you are comparing options, it also helps to confirm whether the application needs current limit/torque control, a specific enclosure style, or accessories such as a plug-in horsepower resistor and armature fuse matched to the motor. Motordrives Australia can help narrow the range and guide a suitable drive option based on the application details.
