Parameters of stimulation Pulse length: 0.1 ms min (externally controlled) Frequency: 0-5000 Hz (externally controlled)

Pulse length: 0.3-20/30* ms (externally controlled)  Frequency: 0-500 Hz (externally controlled)

Pulse length: 0.1 ms min (externally controlled) Frequency: 0-5000 Hz (externally controlled)

1 – Weight depends on the level of mechanical protection of the stimulators and may slightly differ from that stated in the table.
2 – Customized design permits entirely autonomous functions.
3 – There are two current diapasons available for the wireless electrical stimulators: 0 – 50 uA or over 50 uA, e.g. 50 – 500 uA or 50 – 1500 uA  etc.
4 – Time of work on one battery depends on the parameters of stimulation (intensity, pulse width and frequency).
