In many cases the power supplies are specified by their output ratings, in terms of current, voltage and maximum power, but what about their integration in the final application?

Many aspects needs to be considered when choosing one power unit model over the other.

Control interface type, communication speed, regulation modes, internal protections, external signals as triggers, control inputs, configurability, ease of upgrading and flexibility are all very important information that can really make one power device suitable and another one unusable for the particular application and installation.

In this brief overview, the main differences between two bipolar power supplies, the FAST-PS and the EASY-DRIVER having an “overlap” in terms of output ratings are shown in order to let users choose upon their specific needs.

A summary of the unit main specifications and features is hereafter shown:

This previous table act as a selection guide for users that can check what their needs are.

Despite both series have a ±5 A / ±20 V model in their catalogue, their functionalities are similar only regarding the output current and voltage when operating the units in current-control mode (or C.C. = Constant Current) mode.

If there’s a need to perform fast waveforms on the output then the FAST-PS is the most suitable choice for that. If the waveforms can be slower, then also the EASY-DRIVER can be a good candidate and the waveform can be perfomed by using the Ethernet interface and by updating the output remotely at a minimum update period of 4 ms – i.e. 250 Hz.

We strongly suggest to consult the Product Presentation documents that are present  on each product page and, to find even more detailed information, the User’s Manuals.
