Variable Speed Drives
Variable Speed Drives
VSDs provide precise electrical motor control so that motor speeds can be ramped up and down and maintained at speeds required (by varying the frequency and voltage supplied to the electric motor). Doing so motors utilise only the energy required rather than running at constant (fixed) speed and utilising an excess of energy.
Soft Starters
Soft Starters
A Soft Starter is a device that starts motors with reduced power supplied at start-up. 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
Solar Drives
A Solar Drive (for water pumps) is a type of electrical converter (essentially solar-powered VSDs) 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 electrical water pump motor (also still allows for an AC input supply if required). Solar Drives thus provides an energy efficient, environmentally friendly way to pump water for a variety of purposes.
Servo's
Servo's
A Servo Drive is a special electronic amplifier used to power electric servomechanisms to amplify performance in terms of the desired velocity, torque, and position/angle, as well as stiffness, and damping. The main task of a Servo Drive is to monitor feedback and continually adjust for deviation from expected behaviour (closed loop system).
