EA-PUL 11000-160 6U Programmable Electronic DC Load with Energy Recovery

The EA-PUL 11000-160 6U is a high-performance, bidirectional DC load system featuring advanced energy recovery technology. As part of the EA-PUL 10000 series, this 60 kW unit is designed for demanding applications such as testing high-power programmable DC power supplies, computer power supplies, battery systems, fuel cells, and on-board chargers (OBC). It operates as a regenerative electronic load, feeding up to 96% of the absorbed DC power back into the AC grid, dramatically reducing energy costs and heat dissipation. With a wide autoranging DC input of 0-1000 V and 0-160 A, it offers exceptional flexibility. The unit supports CV, CC, CP, and CR regulation modes with fast crossover and high accuracy. Equipped with a Master-Slave bus and Share-Bus, up to 64 units can be paralleled to create systems up to 3840 kW, behaving as a single, cohesive system.

Key Features

• Regenerative & Efficient: Recovers energy to the grid with up to 95.8% efficiency, reducing operating costs and cooling requirements.
• High Power & Autoranging: Delivers 60 kW within a wide 0-1000 V / 0-160 A range, eliminating the need for multiple fixed-range loads.
