3. ELECTRICAL
SUPPLY
3.1.Input
Voltage:- The Atomiser needs a supply of 10 - 25
VoltsDC, Absolute Maximum 30 VDC.
The speed of the Spray Head is proportional to the voltage applied; maximum
speed is at 25 V. There is a speed limiter incorporated in the
electronics of the Atomiser, set at 32,500 rpm.
Input voltages higher than 30 VDC will destroy the electronics.
3.2.
Input Current:- Current consumption
is proportional to speed, and the liquid flow rate through the
unit. There is a current limiter incorporated in the electronics
of the Atomiser, set at 2 Amps.
A special Power Supply for the Atomiser, allowing operation from the 230/115
VAC mains supply, is available from Newland
Design - this unit also has a speed control. A 24 V battery supply is
also suitable.
The Atomiser's body is electrically isolated but can be connected to earth
if required.
3.3.
Connector:->The Power Lead to the Atomiser is normally
fitted with a ¼" jack plug connector, which fits in the socket on the Newland Design
Power Supply unit. At option 4 mm plugs, or any other connector specified by the customer at time of ordering can be fitted.
The motor
in the Atomiser is a BRUSHLESS DC motor which will NOT operate
on a reversed-polarity supply. Be sure to connect correctly!
(Brown or Red = +ve, Blue or Black = 0V). Prolonged connection
to reverse polarity will destroy the electronics in the Atomiser,
and may damage the supply.
