Many types of electrical equipment work perfectly well on a voltage lower than the standard mains supply. This is particularly true for equipment designed to operate on 380V or 400V three phase supplies where the supply is 415V. The actual power supply is higher than necessary the equipment will consume more power than needed and in many cases, equipment life is reduced, effectively increasing the cost of ownership. Energy Saving Transformer (EST) helps organizations make some of the biggest financial savings possible on their energy bills by reducing the mains voltage used to power electrical equipment. It is a tapped auto-transformer which reduces voltage by up to 12% by a fixed amount, making it ideal for sites with a reasonably stable voltage supply. At full load the EST Voltage Optimization delivers efficiency of more than 99% which can realize energy savings of up to 20%.

MODERN Frequency Converters are available in several different configurations to suit any frequency conversion need. Inputs and outputs are available in any combination of 50, 60, and 400 Hz. Frequency converters are very commonly used to test products designed for use in a different country before it is shipped. Using a frequency converter allows you to precisely emulate the grid power of your target environment in a controlled laboratory setting. They may also be employed when powering machinery from overseas.

With other harmonic filtering solutions, expensive and time consuming site data collection, power quality surveys and computer generated studies are usually needed. Most harmonic filters are designed to accommodate just one or a few harmonic orders. The MODERN Active Power Filter(APF) corrects a full range of harmonic orders, and will not create a resonance condition with existing equipment. The APF injects compensating current into the load to restore the sine wave and dramatically reduce distortion to less than 5% THD. Its high speed process cancels high frequency output current, while it determines the precise value of injected load current. The MODERN APF provides the simplest and most effective means to mitigate harmonics, reduce process-related voltage fluctuations, and improve equipment operating life and system capacity.
