The microprocessor controlled laboratory power supplies of series EA-PSI 5000 A offer a set of useful standard features, which can facilitate operation. Set values, actual values and status are clearly displayed at the same time on the blue, illuminated LCD, in order to have them at one glance. The implemented supervision features for all output parameters can help to reduce test equipment and make it almost unnecessary to install external supervision hardware and software. The clearly arranged control panel with its two knobs and five pushbuttons enables the user to handle the device easily with a few touches of a finger. For the integration into remotely controlled laboratory applications and small test systems, the devices offer a set of interfaces (analog and digital) on their rear side.
