Liberty Made® TENS 3 (Analog TENS Unit)



 The Liberty Made® TENS 3

is a high quality TENS unit that uses the newest technology of a microprocessor, which gives exact dial performance. The Liberty Made® TENS 3 has the ease of operation of an analog unit with the accuracy of a digital unit! The Liberty Made® TENS 3 comes standard with a Safety Amplitude Cap, which is a transparent pivot­ing cap that closes over the amplitude knobs to help protect the user from power jolts from accidental knob movements.

The Liberty Made® TENS 3 is a dual-channel device with 3 modes of operation (B,N,M). Both its pulse width and frequency are adjustable. It also comes equipped with a 30, 60, and 90 minute timer. Case included.

Technical Specifications:

  • Channel: Dual, isolated between channels
  • Pulse Amplitude: Adjustable, 0-80 mA peak into 500 ohm load each channel
  • Pulse Rate: Adjustable, from 2 to 150 Hz
  • Pulse Width: Adjustable, from 30 to 260 microseconds
  • Modulation Mode: Pulse rate is automatically varied in a cyclic pattern over an interval of nominally 10 seconds (in max 1150 Hz). Pulse rate decreases linearly over a period of 4 seconds from the control setting value to a value which is 40% less. The lower pulse rate will continue for 1 second. Then increase linearly over a 4 second period to its original value. The original pulse rate will continue for 1 second. The cycle is then repeated.
