12. GENERAL FEATURES AND MODELS
12.1 Ultrasonic humidifier models for fan coils
and electrical specifications
The table below summarises the 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, 10 m
(32.8 ft) long; compliance with standards in force is always required;
(4) max instant rated atomised water production: average atomized water production may
depend on external factors, such as: room temperature, water quality, atomised
water production distribution system
Important:
to avoid interference, keep power cables separate
from probe cables.
