Arbitrary DC power supplies
The main reason for the use of DC power supplies is often to generate a stable DC voltage, or to supply a stable DC current.
Arbitrary DC power supplies however can generate relatively rapid variations of both voltage and current.
It is designated an arbitrary DC power supply, if these variations take place within one quadrant (that is, both voltage and current remain positive at all times).
TTMS also has two-quadrant and regenerative two-quadrant arbitrary DC power supplies in its product portfolio.
Applications for these power supplies are, for example, simulation of the start pulse in automotive technique, control of a DC-motor with a specific profile to simulate the consumption of an electric car, or simulation of network pollution on a DC network to gather knowledge on the consequences of a voltage dip.
To this purpose, dynamic specifications such as rise and fall times are listed for arbitrary DC power supplies. For some models, even the bandwidth is specified.
For applications with arbitrary DC power supplies, two-quadrant power supplies, and regenerative two-quadrant power supplies, we recommend to contact one of our T&M consultants to discuss the possibilities of your specific application.
We don’t buy measuring instruments, we purchase solutions for specific measurement problems. I like to buy from TTMS, given their knowledge of test solutions in power electronics. I hate sellers. TTMS helps us to make the right choice. They even come up with instrumentation from manufacturers they do not represent themselves. And always with the perfect service: they are not complicated and just arrange what is needed.

In my role within the calibration and quality lab, it is a continuous striving for quality for me. In order to ensure this, the right support from, amongst others, suppliers is essential. TTMS understands this like no other, and I have been doing business with them for years. If I need to describe the business relationship with TTMS, it would be that it’s both constructive and instinctive. The measurement instrumentation is reliable.
In addition to this, TTMS’ expertise of test and measuring equipment complements the STCA.
