The EA-PUL 12000-80 is a programmable, regenerative electronic DC load engineered for high-voltage testing and scalable multi-unit systems.

Overview

• Programmable 60 kW DC electronic load with a wide DC input range and high-efficiency regenerative energy recovery to the AC grid, reducing operating costs and cooling requirements.
• Designed for battery testing (SOH/EOL), fuel cell characterization, on-board charger (OBC) testing and battery recycling/discharge processes, with features for precise control and scalable integration.

Key Features

• Energy recovery (regenerative) design feeding absorbed DC energy back into the AC grid with efficiency up to 96.5%.
• Wide AC input capability with active Power Factor Correction (typ. 0.99) for industrial environments (3-phase 380–480 VAC ±10%).
• Autoranging input stages and constant-power capability (U/I/P autoranging) maintaining full rated power across voltage/current conditions.
• Multiple regulation modes: CV, CC, CP, CR with fast crossover and digital control (16-bit ADC/DAC).
• Scalable parallel operation via galvanically isolated Master-Slave bus and Share-Bus—up to 64 units in parallel (mixed power classes from 5 kW) for systems up to 3840 kW.
• Comprehensive built-in and optional interfaces for automated test integration: Analogue 0–5V / 0–10V, USB, LAN (Ethernet), Analog (DB15); optional CAN, CANopen, Modbus, Profinet, EtherCAT, RS232, Profibus, DeviceNet.
• Robust protection: OVP, OCP, OPP and overtemperature protection.
• Built-in function generator and touch panel human interface for test sequence control.
