EA Elektro-Automatik High-Density DC Power Supply Series
60 kW DC Power Supplies and Loads Achieve Breakthrough in Power Density

EA Elektro-Automatik GmbH & Co. KG, a global leader in DC power supply design and manufacturing, introduces the 60 kW and 30 kW EA-PU 10000 programmable DC power supplies, EA-PUB 10000 programmable bidirectional DC power supplies, and EA-PUL programmable regenerative DC electronic loads. Typical applications include EV battery pack testing, furnace power supply for semiconductor wafer fabrication, electrochemical water treatment, and solar inverter testing. These new products are designed without a front panel display, specifically for high-power production ATE systems and automated control systems.

The 60 kW models have a maximum output voltage range from 360V to 2000V and a current range of 480A to 80A, while the 30 kW models have a maximum output voltage range from 60V to 2000V and a current range of 1000A to 40A. The enhanced power capacity allows engineers to reduce the number of power instruments needed in high-power systems, saving critical rack space and delivering more power in a smaller footprint.

EA Elektro-Automatik offers 60 kW of power in a 6U housing and 30 kW in a 4U housing, achieving industry-leading power density. These space-saving, cost-effective solutions prioritize safety and minimize total cost of ownership. All models come equipped with overcurrent, overvoltage, overpower, and thermal protection. The new bidirectional power supplies and regenerative electronic loads feature a power factor of 0.99 and can return up to 96% of recovered power to the grid.

 

 

Scalable System Capacity up to 3.84 MW

Test engineers can parallel up to 64 power supplies and loads in the 10000 series using a master-slave bus configuration, enabling one device to control all instruments in the system for a combined output of up to 3.84 MW. The system can include any combination of instrument models from the 10000 series. Each device features a current-sharing bus interface to safely distribute load requirements across all instruments, ensuring no device in the system is overloaded.

 

Reduce Instrument Costs and Rack Space

With up to 60 kW of capacity in one chassis, engineers can significantly reduce the number of power instruments needed for high-power systems, cutting capital costs and saving valuable rack space. Furthermore, the removal of front panel displays further lowers equipment expenses.

 

Save Development Time with Seamless Operation Across All Models

All instruments in the 10000 series run on the same firmware and share similar input and output characteristics. This uniformity streamlines the development and setup of test and control systems that require multiple power instruments, saving engineers time during testing and programming.

 

Enhanced Voltage and Current Flexibility with True Auto-Range Technology

All 10000 series instruments feature auto-ranging outputs (or inputs, for electronic loads). Unlike conventional power supplies or loads with rectangular output/input characteristics, auto-ranging provides higher voltage capacity at low currents and higher current capacity at low voltages. Instruments with auto-adjustable output/input ranges maintain full power across a larger portion of their operating area, in contrast to rectangular-output instruments, which only achieve maximum power at their highest voltage and current. EA’s true auto-range technology offers a wider range of voltage and current options compared to competing products with auto-range functionality, giving engineers greater flexibility for various testing needs.

 

Simulate Power Devices and Generate AC+DC Signals with Optional Built-In Arbitrary Waveform Generator

The EA-PU, EA-PUB, and EA-PUL instruments come equipped with an onboard full-function generator (available as a software option) capable of creating complex signals based on DC bias to simulate various device characteristics, such as solar panels, batteries, and fuel cells. Specialized features support maximum power point tracking (MPPT) as well as EN 50530 solar inverter testing. Additionally, LV123, LV124, and LV148 standards-based test sequences are available for testing automotive components and systems. The optional built-in function generator eliminates the need for external waveform generators, simplifying the process of simulating devices and creating output (or input) sequences to meet critical testing standards.

 

Communication with PCs and Programmable Logic Controllers (PLCs)

The 10000 series instruments are designed to function efficiently in PC-controlled test systems and PLC-controlled industrial processes. Engineers can easily program the instruments using SCPI or ModBus protocols. The instruments offer a wide range of galvanically isolated interfaces, including standard options like Ethernet, USB, and analog interfaces, as well as optional interfaces such as CAN, CANopen, RS-232, Profibus, ModBus, Profinet, and EtherCat.
