Overheating protection function
Eco Products
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 fire. To prevent this from occurring, Sony Denki’s fans incorporate an over-
heating protection function. Refer to the catalog for the types of protection functions.
●Impedance protection
This system is used for shading coil-type fans. When the blades are restricted, the current is reduced by the imped-
ance 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.
●Thermal protection
This system is used for condenser phase-type fans. A temperature sensor is incorporated in the coil so that if the
temperature exceeds the specification temperature, the current is cut off to prevent overheating of the coil.
●Current cutoff system
If the fan blades are restricted, the coil current is cut off at regular cycles to prevent overheating of the coil. When
the hindrance is removed, the fan restarts automatically. (For the San Ace 200 E Type, however, the power needs
to be turned off and on again to restart.).
Sanyo Denki's ECO PRODUCTS are designed with the concept of lessening impact on the environment in the
process from product development to waste.The product units and packaging materials are designed for
reduced environmental impact.We have established our own assessment criteria on the environmental impacts
applicable to all processes,ranging from design to manufacture.Those products that satisfy the criteria are
accredited as ECO PRODUCTS.
