Characteristics

I.Constant Output Power: The design of this kind of high frequency generator has been simplified based on the CHW-E17I Model High Frequency Electrotome, canceling the functions of bipolar coagulation, blend 2 and blend 3, and featuring with almost the same characteristics as Model I High Frequency Eletrotome, such as controlling performance, output power and safety performance,which reduces the cost and is more suitable for ordinary surgical users of medium or small-sized hospitals.

II. Excellent Safety:Because CCHW-E17III adopts the full-bridge non-industrial frequency transformer high frequency switch power supply as the power source for high frequency power amplifier,the application portion of the Generator has dual insulation from the power supply of the power network, which promotes the safety guarantee for the users and the patients.

III. High Reliability: CHW-E17III is made by advanced circuit design, which has corresponding actuations for circuit protection against various load variations in order to guarantee the normal functioning of active transistor. The comprehensively designed control circuit has strong capability against common fault operations. Besides that the critical portions adopt the imported units, the strict filtering realizes the more superior quality level of the entire CCHW-E17III.

IV.The performance-to-price ratio is high: The electrocision and coagulation performance like CHW-E17I type machine,further reduce at the price.
