• Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications. (1/3) Ultrasonic Nebulizer Units Incorporate Type NB Series The TDK ultrasonic humidifier unit was the first such product in the world to be developed. There is an increasing need for indoor humidification due to the proliferation of clean air heat pumps and central heating systems. When the appropriate amount of humidity is added as determined by the relationship between humidity and sensible temperature (temperature perceived by the body), humidification is advanta- ELECTRICAL CHARACTERISTICS geous from the standpoint of both health and reduced energy consumption. In addition to such home uses, these ultrasonic humidifier units have numerous advantages for humidification of vegetable showcases, preservation and growth of agricultural products, industrial applications, etc. A wide variety of standard units are available from TDK.

MOUNTINGS (Reference) 1.NB59S, NB-80E TYPES The transducer can beak off if the A dimension depth is shallow. TDK recommends a 2mm A-dimension depth and a screw tightening torque of 0.6N•m. 2.CONSTRUCTION OF NB59S The drawing below shows an example method for transistor heat dissipation. The attached aluminum cooling fins should fixed using silicon rubber to a metallic water tank, etc. with sufficient head dissipation capacity. (It is recommended to use a plastic water tank. However, if a metallic water tank is absolutely must be used, be sure to insulate it from the power supply line.) PRECAUTIONS • These units are readily damaged by operation when empty (without water). Therefore a means (float switch, etc.) should be provided to assure operation does not occur when empty. • Con...
