Datasheet

Delivering up to 300kW per rack, the EA-10000 Industrial Series provides a powerful and efficient DC power testing solution by combining bidirectional, regenerative, and conventional DC power units within a single platform. With energy recovery exceeding 96%, the system helps reduce operating costs while enabling seamless integration of multiple units through a unified firmware architecture.

Designed for high-power and regenerative testing applications, the EA-PUB Series returns absorbed energy back to the grid with more than 96% efficiency, making large-scale battery emulation and battery testing both cost-effective and energy-efficient.

The series includes three power unit types: PUB for bidirectional operation, PUL for regenerative load functionality, and PU as a conventional programmable DC power supply

Modular, High Power in Fewer Units

Bidirectional DC Power Supply Ideal for Battery Emulation

The EA-PUB Series bidirectional DC power supplies enable realistic battery emulation through programmable voltage, current, and resistance control. This supports advanced testing of EV systems, energy storage solutions, power electronics, and other DC-powered devices without requiring physical batteries, while regenerative operation improves overall energy efficiency.

• Programmable battery emulation

• Voltage, current, and resistance control

• EV and energy storage testing support

• Regenerative operation for improved efficiency

Autoranging for Seamless Power

The EA-PUB / PUL / PU Series incorporates true autoranging technology, enabling maximum output power across a wide range of voltage and current combinations. Unlike conventional power supplies that achieve full power only at rated voltage and current, autoranging ensures efficient utilization of available power throughout the operating range.

• Full power across a wider operating envelope

• Increased flexibility for test engineers

• Efficient utilization of installed power

• Reduced need for multiple dedicated systems

Regenerative Battery Testing for Energy Savings

The PUL and PUB models utilize regenerative technology that recovers up to 96% of absorbed energy during testing. Instead of dissipating energy as heat, recovered power is returned to the local facility grid or public utility network, reducing energy costs and improving overall test efficiency.

• Up to 96% energy recovery

• Reduced cooling requirements

• Lower operating costs

• Improved sustainability and efficiency

Optional Water Cooling (4U & 6U)

Water-cooled configurations are available for demanding industrial environments. These models efficiently dissipate heat, reduce acoustic noise levels, and help maintain long-term reliability under continuous high-power operation.

• Enhanced thermal management

• Reduced operating noise

• Increased reliability in harsh environments

• Optimized for continuous industrial testing
