Description

The bidirectional DC laboratory power supplies in the PSB 10000 series from EA Elektro-Automatik are two quadrant devices which can perform the function of a power supply (source) as well as that of an electronic load (sink). In sink mode the device is regenerative and feeds the energy back into the local grid with an efficiency of up to 96%. The PSB 10000 series includes single and three phase units which, together with the wide input range, allows use with prac- tically all global mains voltages. The DC voltages and cur- rents are determined by the application and the spectrum ranges from 0 - 10 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 character- istic (autoranging) with 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 PSB or PSBE 10000 range. Fur- thermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warn- ing management, various industrial interfaces, software solutions and many more functions.
