New Compact DC Power Supply from Lake Shore
- Programmable current output, 100 nA to 100 mA
- Current reversal feature
- 7 decades of low-noise output current, selectable in 13 steps
Lake Shore’s new Model 121 programmable DC current source is a CE-marked precision instrument suitable for bench-top use or panel-mounted operation in labs, test facilities, and manufacturing environments.
The Model 121 provides a low-noise, highly stable source of current up to 100 mA, with convenient manual selection through 13 pre-set output levels, each representing a ten-fold change in power when attached to a resistive load. A “user” setting allows the current output to be defined anywhere within the operating range of the unit, from 100 nA to 100 mA.
Programmable operation is also possible via the instrument’s USB computer interface, through which the Model 121 can be commanded to output any desired current at any time. Thus, application-specific test currents can be driven from an external PC.
