 3. Frequency adjustable from 2Hz to 160Hz continuously; 

 4. Pulse width adjustable from 20μs to 500μs continuously; 

 5. Each output group's intensity can be adjusted continuously from 0 to 100mA; 

 6. Accurate timing, with six selectable time settings from 5 to 30 minutes; 

 Kangda KD-2A Transcutaneous Electrical Nerve Stimulator Features: 

 1. Computer-controlled low-frequency pulse therapy device, suitable for transcutaneous electrical nerve stimulation, neuromuscular electrical stimulation, and particularly ideal for electroacupuncture therapy, offering multiple functions in one device; 

 2. Outputs three channels of low-frequency pulse current, allowing simultaneous treatment of three patients or three areas; 

 3. Three treatment modes can be switched: continuous output, slow intermittent output, and fast intermittent output, suitable for various therapeutic purposes; 

 4. Pulse width, output intensity, and a wide range of pulse frequencies can all be adjusted continuously; 

 5. Timing settings: 5, 10, 15, 20, 25, and 30 minutes divided into six selectable levels, with an alarm function at the end of treatment. Additionally, an indefinite timing function has been added to meet the needs of prolonged treatments such as post-operative pain relief. 

 Main Technical Parameters: 

 (1) Output pulse waveform: bidirectional asymmetric square wave. 

 (2) Output pulse width: 20μs to 500μs, tolerance ±20%. 

 (3) Output pulse frequency: continuously adjustable from 2Hz to 160Hz, tolerance ±10%. 

 (4) Output current: Among the three groups of current, the peak current Ip for each group should be greater than 100mA and less than 120mA when measured with a 1kΩ load resistor. 

 (5) Maximum output voltage: When the output terminal is open, the peak output voltage should not exceed 500V.
