AC COOLING FAN - SANYO DENKI EUROPE - #47

Text version of the page

46 GND should be shared in case that power supply for sensor circuit and that for sensor pull-up are separated. AC Fan Common Specifi cations Protection Functions If the fan blades are restricted, an overcurrent occurs and leads to a rise in the fan coil temperature. This can result in reduced performance, damage, or a fi re. To prevent this from occurring, Sanyo Denki’s fans incorporate an overheating protection function. Burnout protection function at locked rotor condition �œImpedance protection (60mm sq. 80mm sq. 92mm sq. 120mm sq.) This system is used for shading coil-type fans. When the blades are restricted, the current is reduced by the impedance of the coil itself to prevent a temperature rise in the coil. However, if the applied voltage exceeds the specifi cation range, an overcurrent can occur and result in overheating, and so care needs to be taken. �œThermal protection (160mm sq. ö172mm) This system is used for condenser phase-type fans. A temperature sensor is incorporated in the coil so that if the temperature exceeds the specifi cation temperature, the current is cut off to prevent overheating of the coil.
