Description

The DC laboratory power supplies in the PSI 10000 series from EA Elektro-Automatik convert the energy from the grid into a regulated DC voltage with an efficiency of over 96%. The PSI 10000 series includes single and three phase units, which, together with the wide input range, allows use with practically all global mains voltages. The DC voltage and current ratings are determined by typical applications and the spectrum ranges from 0 - 60 V to 0 - 2000 V and from 0 - 6 A up to 0 - 1000 A in a single device. The DC supply operates as a flexible output stage with a constant power characteristic (autoranging) and a wide voltage and current range.

To achieve higher power and current all units are equipped with a master-slave bus. This enables up to 64 parallel con- nected devices to be combined into one system which can provide up to 1920 kW and 64000 A. Such a system works as a single unit and can use different power classes, only the voltage class must remain constant. In this way a user can construct a 75 kW system from two 30 kW 4U and one 15 kW 3U device from the PSI 10000 range.

Furthermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warning management, various optiona l industrial interfac- es, software solutions and many more functions.
