EA Elecktro-Automatik EA-PSB 12000-40 Bi-Directional Power Supply, 0 to 2000 V, 0 to 40 A, 30 kW, 208 Vac

EA Elektro-Automatik EA PSB 12000-40 Bi-Directional DC Power Supply, 0 to 2000 Vdc, 0 to 40 A

The Elektro-Automatik EA-PSB 12000-40 is a two-quadrant device that can function as both a power supply and an electronic load. In sink mode, the device is regenerative and feeds the energy back into the local grid with an efficiency of up to 96%. The DC supply operates as a flexible output stage with a constant-power characteristic (auto-ranging) 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-connected devices to be combined into one system, providing 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. Furthermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warning management, various optional industrial interfaces, software solutions, and many more functions.

AC connection
The PSB 12000-40 is equipped with an active PFC, which provides high efficiency at a low energy consumption. This device can be operated on most global grids with a wide input voltage range from 208 V to 380/400/480 V, 3-phase. It automatically adjusts to the available grid voltage without additional configuration. In a 208 V AC grid, the DC output power is automatically derated.
