22/46 Ultrasonic Controller
The high frequency electrical energy required by the spray nozzle is provided by
the Broadband Ultrasonic Controller. This power source offers an array of fea­
tures that both simplify and enhance the operation of the nozzle systems:
• Advanced phase­locked­loop control technology to automatically lock onto a
nozzle’s specific operating frequency.
• Regulated output assures that the power delivered to a nozzle remains con­
stant.
• Provides alarms in the event of system malfunction or critical temperature
being reached.
• LCD power meter and power level control for setup and monitoring.
• Temperature control.
• 100–240 VAC free­standing system.
