Core Construction

• 01 Digital Display: Simplified front panel layout designed for straightforward operation.
• 02 Independent R&D: Proprietary full-bridge circuit topology ensures low power loss and stable electrical output.
• 03 3D Cooling System: High-volume cooling fan paired with louvered side vents dissipates heat directly, protects the internal circuit, and extends equipment service life.

Technical Specifications

Applications

• Precision parts cleaning in electronics, medical, and optics manufacturing
• Immersible transducer boxes and bar-type ultrasonic vibrating rods
• Laboratory ultrasonic cleaning, degassing, and sample testing
• Nanomaterial dispersion, liquid emulsification, and ultrasonic extraction

Wiring & Installation Instructions

• Power Input: Connect the industrial power cord to the marked AC terminal (100V-120V ~ 60Hz or 220V-240V ~ 50Hz according to unit rating).
• Transducer Output Port: Connect the ultrasonic immersible box, plate, or bar array to the high-frequency output terminal.
• Grounding (GND): Connect the ground line directly to the designated chassis grounding terminal to prevent electrical leakage.
• Remote Control Port (Optional): Use the interface port (DB9 or industrial connector) to connect external PLC lines for remote ON/OFF, frequency selection, and power output adjustment.
• Cooling Clearance: Maintain open space around all side and rear ventilation louvers. Do not operate within an unventilated sealed cabinet.
