Buy / Rent
Datasheet

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

Designed for high power and regenerative performance, the EA-PUB returns energy back to the grid with more than 96% efficiency, making large scale industrial battery emulation both cost effective and more sustainable.

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

Modular, High Power in Fewer Units

Bidirectional DC Power Supply Ideal for Battery Emulation

The Tektronix-EA PUB Series bidirectional DC power supplies emulate real battery behavior with programmable voltage, current, and resistance. This enables safe, repeatable testing of EV components, storage systems, and electronics—without physical batteries—while regenerative recovery improves efficiency.

Autoranging for Seamless Power

The Tektronix-EA-PUB/PUL/PU Series provides autoranging, delivering maximum power across a wide range of voltages and currents. Unlike traditional power supplies, which only reach full power at maximum voltage and current, autoranging ensures your battery tester maintains full output under real-world conditions. This allows a single tester to handle multiple voltage and current combinations.

Regenerative Battery Testing for Energy Savings

The PUB and PUL load models have regenerative technology that recovers up to 96% of the energy used during testing. Instead of wasting power as heat like traditional loads, recovered energy is fed back into the local grid—or even the public grid—reducing facility costs and improving test efficiency.

Optional Water Cooling (4U & 6U)

Water-cooled models ensure stable operation in harsh industrial environments, efficiently dissipate heat, reduce noise, and maintain reliability under challenging conditions.
