The DC laboratory power supplies in the PS 10000 series from EA Elektro-Automatik convert the energy from the grid into a regulated DC voltage with an efficiency of over 96%. The PS 10000 series includes single and three-phase units, which, together with the wide input range, allow use with practically all global mains voltages. The DC voltage and current are directed by the application 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, current, and power range. To achieve higher power and current all units are equipped with a master-slave bus. This enables up to 64 parallel connected devices to be combined into one system which can provide up to 1920 W 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 and one 15 kW devices from the PS 10000 range. Furthermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warning management, assorted interfaces and ports, software solutions, and many more functions.

AC Connection

The DC power supplies in the PS 10000 series are equipped with an active PFC which provides high efficiency at low energy consumption. Furthermore, the devices in this series provide a wide input voltage range. This extends from 1-phase 110/120 V up to 240 V AC mains supply and 3-phase 208 V to 380 V, 400 V, and 480 V AC mains supply. The devices can be operated in the majority of global mains supply. They adjust automatically, without additional configuration, to the available supply. In a 110/120 V and 208 V AC grid, a derating of the output power is set.

DC Output

The output of the bidirectional power supply PS 10000 with a DC voltage of 0 - 60 V up to 0 - 2000 V allows currents of 0 - 6 A up to 0 - 1000 A. The flexible output stages (autoranging) provide the user with a wide voltage, current and power range and hence a wider field of working than traditional power supplies.

DC Connection

Connection of the DC output is via a copper rail on the back side of the device. If a system with higher performance is required. the devices are simply connected in parallel. With minimal effort devices can be linked with the vertical copper rails. A cover for contact protection is provided.
