3-channel ultra high precision voltage sources
The UM 1-5/1-14 LN is the latest family member of our series of 3-channel ultra high
precision voltage sources.
It features a further improved temperature-coefficient and even less voltage fluctuations on a 10E-8 level.
The device represents the preferential choice for applications needing up to 3 precision voltage outputs
in the +/-14V range and is currently unrivalled in its class. Please read more in the
 Data Sheet (pdf, 2 MB)
Key Features:
- 3 Channels
- 10ppm Base Accuracy
- Fluctuations on 10E-8 level

Ultrastable bipolar voltage source UM 1-5b
The UM 1-5b is an ultra high precision bipolar voltage source. It offers three independent channels,
each resolved with 25Bit, +/-14V and +/-3.5V range. It is the first device on the market
having three independent voltage channels with better 0.1ppm resolution and stability. It
shows an unrivalled combination of resolution, stability and long term drift, making it ideal
for quantum computing and high precision ion trap based spectrometry.
It's e.g. in use at the University of Mainz, Department of Physics in the  g-factor proton experiment
and the g-factor calcium experiment.

Precision multichannel voltage sources of the BS Series
|
Our new BS Series devices provide precise and stable DC voltages up to +/-14V for
biasing purposes. Unlike DC power supplies, the outputs currents are limited to small
values, and the outputs are optimized for high short and long term stability, low noise
and low temperature drift. The device is housed in a standard 19-inch rack-mount case.
User control of the device can be accomplished by PC control programs, utilizing a
standard USB connection (USB 2.0 compatible). The programmed voltages and measured
output currents are displayed on the front LCD display. Read more in the
