Digitimer DS2A (Constant voltage)

The DS2A Mk.II (Constant voltage) provides a precise Constant Voltage stimulus (up to 100V) controllable in Pulse Duration and Amplitude from self-contained batteries, making it ideally suited to electrophysiological recording in small preparations or cells where low noise is required. The DS2A can be triggered by an external device such as our new DG2A Train/Delay Generator. This stimulator is NOT approved for use on human subjects. The DS2A can be fitted into a 19" rack mounting frame (D121-11) which can hold up to two DS2A's, DS3's DS4's or DG2A's.

Please note: Important! This product is for research applications only. Not a medical device as defined in EU directive 93/42/EEC. Not designed or intended to be used for diagnosis or treatment of disease.

System Features

  • Low noise battery power supply with up to 99V output
  • Internal (20µs to 2s) or external TTL “gated”control of pulse duration
  • Two voltage ranges (0-9V and 0-99V) allow precise reproducible control of stimulus output
  • Polarity reversal switch
  • Battery test sockets
  • Single-shot trigger button
  • In the case of low impedance preparations, current output is limited t0 50mA by an overload protection circuit
  • Current is only drawn from batteries when a stimulus is being delivered

 

Technical Specifications

  • Output: Between 2μA and 32mA
  • Control: Four selections 10μA, 100μA, 1mA, 10mA
  • Pulse Duration Range: 20μs to 2s
  • Output terminals: A pair of 2mm touch-proof sockets on the front panel spaced at 0.75”
  • Single Shot: A single-shot push button is provided
  • Trigger: A positive pulse of between 3V and 20V is required to trigger the stimulator. The trigger input current varies from 6mA to 62mA over the above voltage range. Trigger pulse duration should not normally be less than 4μs.
  • Dimensions: Panel size: 190mm x 110mm. Depth: 80mm over knobs
  • Weight: 800g complete with batteries
