EL+ vAC/DC Full Regenerative AC/DC Electronic Load

The EL+ vAC/DC is a programmable, full regenerative AC/DC electronic load designed to test AC and DC power sources, inverters, UPS systems, and renewable energy systems by dynamically loading and regenerating absorbed energy back to the grid.

Key features include:

• Full regenerative operation for AC and DC testing

• Programmable CC (Constant Current), CP (Constant Power), CR (Constant Resistance), and CV (Constant Voltage) modes

• Low Total Harmonic Distortion (THD)

• Advanced measurement capabilities and high dynamic response

• User-friendly touchscreen interface

• Remote control via LAN, USB, RS-232, and GPIB

The EL VAC+DC Regenerative Load supports AC voltages up to 350V L-N (606V L-L), DC voltages up to 1,000V, and frequencies from 30Hz to 100Hz. It also provides high current capabilities based on system configuration. Power ratings range from 30kVA/kW to 630kVA/kW, making it ideal for laboratory testing, R&D, validation, and high-capacity production environments.

Yes, the EL+ vAC/DC is ideal for testing solar inverters, wind inverters, battery systems, and grid-tied renewable energy equipment, providing realistic and programmable load profiles for performance and compliance testing.

The regenerative feature allows energy absorbed during testing to be fed back to the grid, significantly reducing energy consumption, minimizing heat output, and lowering operational costs.

The system includes over-voltage, over-current, over-power, and over-temperature protections, ensuring safety and stability during demanding and continuous testing.
