Insulation Resistance: 10 megohms minimum at 500VDC.
Dielectric Strength: 1 minimum at 2,000 VAC/50-60Hz.
Impedance Protection: The fans are designed in such a way that the wiring will not burn out even if the rotating parts are restricted. The use of incombustible insulating materials assures increased safety.
Operating Temperature: -10˚C to +70˚C for the sleeve bearing. -20˚C to +80˚C for the ball bearing.
Operating Voltage: 110/120V range voltage from 85V to 125V. 220/230V range voltage from 190V to 245V.
