Digitimer DS7AH HV Current Stimulator

Suitable as a general purpose electrical nerve or muscle stimulator, the DS7A provides up to 100mA constant current high voltage pulses of brief duration for percutaneous stimulation during investigation of the electrical activity of nerve and muscle tissue. The DS7A is also commonly used in pain research applications. The output current is continuously variable over the range 0 to 100mA from a maximum compliance voltage of 400V. The DS7AH allows currents up to 1A with a reduced maximum pulse duration limit of 200µs. This model is offered to overcome the difficulties of stimulating deep peripheral nerves, or large muscles such as the quadriceps with large area electrodes.

Since April 2014, the DS7A and DS7AH have included an alternating polarity mode to prevent polarization of the stimulation site and potentially harmful electrolytic effects of longer periods of stimulation.

The DS7A or DS7AH can be triggered by an external device such as our new DG2A Train/Delay Generator. For applications that require a higher output, we recommend our D185 MultiPulse. The DS7A & DS7AH are CE marked medical devices and have been cleared by the FDA for marketing within the USA.
