Variable Speed Drives
Widely used in applications ranging from industrial equipment for power reduction and process improvement.
Soft Starters
A Soft Starter is a device that starts motors with reduced power supplied at start-up. Reducing the power reduces potentially damaging electrical and mechanical shocks on the system.
Solar Drives
A Solar Drive (for water pumps), is a type of electrical converter which converts the variable direct current (DC) output of a PV solar panel into alternating current (AC) that can be used by an electrical water pump motor.
A Servo Drive is a special electronic amplifier used to power electric servomechanisms.

Variable Speed Drives (VSDs)

A Variable Speed Drive (VSD), also referred to as a Variable Frequency Drive (VFD) or AC Drive, is a drive that works on changing the frequency of an AC motor (always refers to and can only be used with AC motors).

VSDs take the fixed-frequency AC supply and convert this to a variable-frequency AC supply. This controls the power use and mechanical power output so that the motor can run at the most efficient speed for the motor and the process. The control of the motor speed can be based on feedback from the process, e.g. flow rate, temperature or pressure, so that process control is improved.

Soft Starters

A Soft Starter is a device that starts motors with reduced power supplied at start-up. reducing the power reduces potentially damaging electrical and mechanical shocks on the system. As the name implies, starters "start" motors, but can also stop, reverse, accelerate and protect them. A Soft Starter is a controller with overload protection.

Soft Starters regulate the amount of current fed to the motor to enable the AC induction motor to speed up in smaller increments, resulting in less current drawn than with a traditional motor starter. Due to decreased voltage, torque is also reduced resulting in a soft/easy start.

Solar Drives (for Water Pumps)

A Solar Drive (for water pumps), is a type of electrical converter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into alternating current (AC) that can be used by a local, on-grid electrical water pump motor.

In addition to this, the Solar Drive output frequency is adjustable in real time according to flow requirements as well as sunlight intensity (Variable Frequency drive capabilities).

Servo Drives

A Servo Drive is a special electronic amplifier used to power electric servomechanisms. A Servo Drive monitors the feedback signals received from the Motor sensors and continually adjusts for deviation from expected behaviour (closed loop system).

This helps to improve overall performance through faster acceleration rates and more precise speed and position control (rotate parts with high efficiency and great precision). In providing continuous adjustment, they amplify performance in terms of the desired velocity, torque, and position / angle, as well as stiffness, and damping.
