14.1 Ultrasonic humidifier models 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 the nominal mains voltage: -15%, +10%;
(2) tolerance on nominal 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 atomised water production may depend on external factors, such as: room temperature, water quality,
atomised water production distribution system
NOTICE:
to avoid interference, keep power cables separate from probe
cables.
