Our EP filter product, to put it simply, is a “tracking filter systemEthat helps improve quality of power supplied.
AC powered equipment is designed to function most efficiently when driven by noise-free “sine waveEpower supply. Poor quality electricity involves electric noise, or waveform distorted by transients or non-linear load and load reflection: such undesirable electricity always adversely affects equipments connected to and operating in a power system line.
In a present-day power system, surge occurring from various equipments and devices is a major factor of contributing to distorting voltage and current waveforms in the power system. Surge results from natural phenomena such as lightning and electrostatic buildup, and also arises from artifacts such as motors, transformers and solenoids. In other words, surge and its adverse effects are unavoidable in any power system.
Our unique “EP Tracking Filter SystemEhas been designed to capture, filter and eliminate surge or high-frequency noise occurring in a power system, allowing the load to be supplied with noise-free sine wave power. The efficiency of equipments protected by the EP tracking filter improves over time, leading to productivity improvement and cut running costs.

The EP-2000 is the most advanced available power solution that is optimized for industrial applications. The patented circuitry of EP-2000 incorporates a variety of innovations to help improve efficiency of a distribution system and to guard connecting equipments powering any process, from home automation to industrial robotics.
