RFHG-27-10KW

OVERVIEW

Hybrid RF Generator For

Arc-Free RF Welding Operation

RFHG-27-4/6/8/10/15

The Hybrid RF Generator combines 2 RF amplifiers. The 1st stage uses Solid State RF Amplifier and the final stage uses Vacuum Tube Amplifier. ONEX RF welders use 27.12 MHz Radio Frequency (RF) or High Frequency energy (HF).

The 1st stage solid state driver amplifier outputs up to 600 watts, which is amplified 20 time by the final stage vacuum tube amplifier generating up to 10KW power. The RF generator is tuned to 50 ohm load. ONEX RF welders use auto-tuner to match the load impedance during RF welding cycle.

RF Generator Power

1000 watt Solid State RF Generator

RF-Generator

27.12 MHz Solid State RF Generator

ONEX RF proudly designs and manufactures all the system electronics and RF amplifiers at Duarte, CA, USA.

The Solid State amplifier is rated at 1000 watts output. We design our RF generators with 100% headroom, which means to generate the 10,000 watt RF power the solid state only puts out 500 watts. 

SSRFG-27-1k Features:

  • Operates on 0-10 vdc from PLC analog module
  • The amplifier uses RF sensor feedback to control final RF output power. 
  • Measures and converts the RF input to linear signal for PLC communication
  • Modular design is also used in our Catheter manufacturing systems at different frequency settings 6.78MHz and 13.56MHz

RF Generator Control Panel

RF-Generator Control Panel

RF Generator Control and Indicator Panel

The Generator Uses Local and Remote Operation switches and indicator light.

The generator can be tested by running it in Local mode when generator is connected to a dummy load (50 ohm 10KW resistor). The indicator lights are lit green when all the internal devices and circuits are in perfect working condition. The system also uses limits for the Grid current, Plate current, and VSWR (Reflected Power Ratio), which are set at ONEX RF. If the system detects over current or high reflection it will automatically stop the generator output. The emergency circuit is connected in series with the RF welding system to stop generator power when E-Stop condition detected.

Functions:

  • Local-Remote SSW
  • RF ON Time Control Timer Knob
