EA PU 11500-60 4U 30000W Lab Power Supply

The DC power supplies in the PU 10000 series from EA Elek-tro-Automatik convert the energy from the grid into a regu-lated DC voltage with an efficiency up to over 96%. The PU 10000 series are three phase units which, together with the wide input range, allows use with practically all global mains voltages. The DC voltages and currents are determined by the application and the spectrum ranges from 0 - 60 V to 0 - 2000 V and from 0 - 40 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) with a wide voltage and current range. To achieve higher pow-er 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 3840 kW and 64000 A. Such a system works as a single unit and can use different power classes start from 5kW, only the voltage class must remain constant. In this way a user can construct a 150 kW system from two 60 kW 6U and one 30 kW 4U device from the PU 10000 range. Furthermore, typi-cal laboratory functionality is provided. This includes alarm and warning management, various optional industrial inter-faces, software solutions and many more functions.

AC connection

The DC power supplies in the PU 10000 series with 30 kW are equipped with an active PFC which provides a high ef-ficiency at a low energy consumption. Furthermore, the devices in this series provide a wide input voltage range. It reaches with 3-phases from 208 - 240 V (with a derating to 18 kW) and 380 - 480 V. Hence the devices can be operated in the majority of global grids.

DC output

The output of the power supply PU 10000 4U with 30 kW with a DC voltage of 0 - 60 V up to 0 - 2000 V allows cur-rents of 0 - 40 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 cop-per rails. A cover for contact protection is provided. 

The principle of autoranging 

„Autoranging“ is a term when a programmable DC power supply automatically offers a wide output range of both, voltage and current, to maintain full power across a wide operation range. This type of solution allows the use of a single unit to address multiple voltage and current combi-nations.

Interfaces

As standard, 10000s series devices are fitted with the most important interfaces and ports which are all galvanically isolated from the DC input. There is an analog interface which can be parameterized for input and output, control and monitoring, of 0 - 5 V or 0 - 10 V for voltage, current, power and resistance, assorted inputs and outputs as well as USB and Ethernet ports. Further optional industrial inter-face for plug & play slot complete the portfolio:

• CAN
• CANopen
• RS232
• Profibus
• EtherCAT
• Profinet, with one or two ports
• Modbus, with one or two ports
• Ethernet, with one or two ports
