DC-STIMULATOR PLUS*
Single Channel Programmable Direct and Alternating Current Stimulator
Microprocessor-controlled constant current source
The DC-STIMULATOR meets the highest safety standards thanks to (hardware- and software-based) multistage monitoring of the current path. By continuously monitoring electrode impedance it can detect insufficient contact with the skin and automatically terminate stimulation.
The device's alphanumeric display and the 4 membrane keys allow various stimulation modes to be selected and stimulation parameters such as current strength, duration, fade in and fade out to be set.
Besides transcranial direct current stimulation (tDCS), the DC-STIMULATOR PLUS also makes it possible to conduct bi-polar stimulation (tACS).
Alternating current and random noise current stimulation (tACS, tRNS) are currently in the research and validation phases.
- 1 channel, unipolar (DC) and bipolar (AC) stimulation possible
- 4 standard modes - single (continuous stimulation) - pulse (cyclical stimulation activation/deactivation) - sinus (sinus wave) - noise (normally distributed)
- Frequencies adjustable up to 250 Hz, phase freely adjustable
- Adjustable current (DC) up to 4,000 µA in increments of 25 µA
- "Study mode" for blind processing of genuine and 'pseudo' stimulation (optional)
- External trigger input and output (optional)
