The ST3 CONSTANT CURRENT STIMULATOR is a battery powered unit that can be used to excite nerve and muscle fibres in elecro physiological experiments. It features fully variable constant current output up to 11 milliamps with the ability to provide up to 90 volts. It accepts a positive trigger input and has three pulse width ranges as well as a 'gated' and 'continuous' output setting. The output is electrically isolated from the trigger input.

Specifications:

• Trigger Voltage +3 to +15 Volts
• Voltage Output Varies up to 90 Volts to maintain current
• Current Output 0 to 11 milliamps
• Pulse Width Variable from 50 microseconds to 100 milliseconds, there is also a 'gated' and 'continuous' setting
• Power source (circuit) One standard 9 Volt Battery
• Power source (high voltage) One 90 Volt Battery Pack
