Save energy costs with energy-efficient VFDs Customers can realise significant savings on their total energy costs by replacing older motor starters with energy-efficient Delta variable frequency drives (VFDs). This is according to ElectroMechanica (EM), a leading local supplier of industrial electrical products, motor control switchgear and electronic automation products, and distributor of Delta VFDs. EM Product Manager, William Cameron says, “Energy is always a factor to consider and should never be taken for granted. We all know the importance of energy efficiency – and the volatility of the supply system due to the recent spell of load shedding reinforces this. Now more than ever customers should be thinking about energy efficiency.” Delta VFDs feature ease-of-use and reliability, which makes them ideal for sectors as diverse as agriculture, manufacturing and refrigeration. “Agriculture is an area of potential growth over the short- and longer-term as farmers are under pressure to save where they can. Using industrial control systems to maximise efficiency is a proven way to optimise energy savings,” Cameron says. EM also supplies Delta’s control products such as PLCs (programmable logic controllers) and HMIs (human machine interfaces) which can integrate seamlessly with the VFD range. Using standard I/O or fieldbus solutions, Delta control equipment has a host of special instructions

or drivers to assist the user in integrating the drive to a larger network with ease. This reduces development time and, in turn, costs. One of Delta’s high-end VFDs, the C2000 series, is a high-performance field-oriented control (FOC) ac drive. It is highly versatile, with a built-in PLC, numerous control options, over 300 parameters, predesigned application features, and a large LCD HMI keypad. With a power range from 0.75 kW to 500 kW (400 V), and a host of optional accessories, it is a powerful partner in industry. Commenting on new developments for 2020, Cameron says EM’s updated catalogue will feature a host of new products, including an extended drive range to meet the requirements of the wider market.
