•Technical reference ➜ Page H-1 •Regulations & Standards ➜ Page I-2 EMU Series ●For detailed information about regulations and standards, please see the Oriental Motor website. Reduced power consumption through the use of a built-in brushless motor. With support for a wide voltage range, the fans can use single-phase 100-240 VAC (50/60 Hz). The same characteristics can be achieved regardless of the frequency used. ■Features Low-Power Consumption Wide Voltage Support By using brushless motors, power consumption is reduced by approximately 72%✽. Can be used with single-phase 100-240 VAC (50/60 Hz) power supply. The same characteristics can be achieved regardless of the frequency used. Lifetime of 60,000 hours (approx. 6 years) By using brushless motors, heat generation can be reduced and unit life is increased 2.2 times✽. ✽Compared to MU1238A-51B. Lightweight The mass of the fan has been lightened by approximately 45%✽ by using resin for the frame. ■Comparison of Specifications and Characteristics between the EMU Series and Conventional Products ◇Specification Comparison Product Item ◇Characteristics Comparison Speed [r/min] Same Characteristics ORIENTAL MOTOR GENERAL CATALOGUE 2017/2018 Features G-20 / System Configuration
