10.1 Ultrasound humidifier models for fan coils and electrical specifications
Electrical data (power supply voltages) of the various models, as well as their functional characteristics. Note that some models can be powered at different
voltages, obviously with different current and humidity production values.

(1) tolerance allowed on rated mains voltage: -15%, +10%;
(2) tolerance on rated values: +5%, -10% (EN 60335-1);
(3) recommended values, referring to PVC or rubber cable in a closed conduit, 20 m (65.6 ft) long; compliance with standards in force is always required;
(4) max instant rated water vapor production: average water vapor production may depend on external factors, such as: room temperature, water quality, water vapor distribution
system.
Important:
to avoid interference, keep power cables separate from probe cables.
