A Variable Speed Drive provides the flexibility of the most important elements of feed preparation solutions: adjusting speed to accommodate mixing standards when blending your grain is a vital element in producing the highest quality feed.

Also known as VSD which is used for power management. Additionally, a VSD can change an incoming electricity supply from Single Phase (240V) or rural Poly Phase (2 x 240V) to 3 Phase (415V). Another advantage of VSD is to control voltage fluctuation for motor factoring and supply.

AFSystems have partnered with Mitsubishi Electric, a world market leader, to design a compact affordable PLC specifically designed for the Agriculture, Brewery and Food sectors

The AFSystems Compact PLC is the new flagship line which sets new standards, delivering performance that was formerly the exclusive domain of larger control systems in a compact package.  PLC Automation Control Panels have an edge over conventional relay based systems. PLC Control Panels we manufacture are highly capable of giving higher output at less power consumption

Why use a Variable Speed Drive

1 – Reduce Energy Consumption and Energy Costs

If you have an application that does not need to be run at full speed, then you can cut down energy costs by controlling the motor with a variable frequency drive, which is one of the benefits of Variable Frequency Drives. VFDs allow you to match the speed of the motor-driven equipment to the load requirement. There is no other method of AC electric motor control that allows you to accomplish this.

Electric motor systems are responsible for more than 65% of the power consumption in industry today. Optimizing motor control systems by installing or upgrading to VFDs can reduce energy consumption in your facility by as much as 70%. Additionally, the utilization of VFDs improves product quality, and reduces production costs. Combining energy efficiency tax incentives, and utility rebates, returns on investment for VFD installations can be as little as 6 months.

2 – Increase Production Through Tighter Process Control

By operating your motors at the most efficient speed for your application, fewer mistakes will occur, and thus, production levels will increase, which earns your company higher revenues. On conveyors and belts you eliminate jerks on start-up allowing high through put.

 3 – Extend Equipment Life and Reduce Maintenance

Your equipment will last longer and will have less downtime due to maintenance when it’s controlled by VFDs ensuring optimal motor application speed. Because of the VFDs optimal control of the motor’s frequency and voltage, the VFD will offer better protection for your motor from issues such as electro thermal overloads, phase protection, under voltage, overvoltage, etc.. When you start a load with a VFD you will not subject the motor or driven load to the “instant shock” of across the line starting, but can start smoothly, thereby eliminating belt, gear and bearing wear. It also is an excellent way to reduce and/or eliminate water hammer since we can have smooth acceleration and deceleration cycles.
