Description
The DS2A Mk.II 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.
System Features
- Two voltage ranges allow precise reproducible control of stimulus output
- Polarity reversal switch
- Battery test sockets
- 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
