    ER-PS-60W Static Frequency


    ER-PS-60W series Static Frequency is one of the most popular static solid-state frequency converters. It is designed to change conventional 50 Hz or 60 Hz electrical energy to virtually any other frequency. It integrates IGBT made by Mitsubishi, Siemens, and combines analog signal control design together for compact size and higher reliability.

    ER-PS-60W as a power source is ideal for export/import testing and operating equipment manufactured in a foreign country. It can simulate any world wide utility as well as shipboard power with clean sine wave output and excellent line and load regulation, high efficiency and low harmonic distortion.
