DS7A & DS7AH Stimulator

The DS7A is a high-voltage constant current stimulator, suitable for percutaneous stimulation of nerves or muscles with short pulses.

The DS7AH is a high-power version offering up to 1 A output on very short pulses (< 200 µs), ideal for deep nerves or large muscles.

DS7A & DS7AH Stimulator features

  • Variable output current: up to 100 mA (DS7A) or 1 A (DS7AH)
  • Compliance voltage up to 400 V
  • Selectable pulse durations: DS7A: 50 µs to 2 ms; DS7AH: 50 µs to 200 µs
  • Toggle polarity control (± or automatic alternating)
  • Flexible triggering: front button, positive TTL or external footswitch; TTL output on BNC
  • CE & FDA 510(k) certified medical device for human use
