Advanced Bidirectional Grid Connected Testing Using Regenerative AC Electronic Load

Product Description

Product Description

ACEL Series Feedback AC Electronic Load

Power Feature

Due to the production and maintenance of high-power power supplies, AC charging piles, generator sets, and various power supply products, which all require high-current discharge, a significant amount of energy is typically consumed through the use of resistive loads, leading to increased production costs and difficulties in ensuring accuracy. Therefore, our company's self-developed feedback type AC electronic loads rectifies AC into DC first, then inverts it back to AC, and feeds it back to the grid, thereby saving energy.

 1.Electric energy can be returned: the energy consumed will be returned to the grid, saving electricity costs, and the feedback rate is high;

 2.Self setting parameters: Users can adjust the discharge power, discharge time, and timing to automatically turn off the load based on performance parameters and detection requirements;

 3.Multiple loads can be connected in parallel: multiple units can be discharged in parallel to adapt to the occasion of high-current discharge;

 4.Good human-computer interaction: 7-inch touch screen , display power, voltage, current, frequency, etc;

 5.Strong anti-interference: Optical fiber drive control is adopted, which has strong anti-electromagnetic interference ability and reliability;

 6.High protection level: The surface of the cabinet is treated with electrostatic spraying, and the PCB is treated with spray paint and glue.
