Regenerative Electronic Load Bank — Energy Recovery Testing

A Regenerative Electronic Load Bank tests electrical power systems (generators, UPS, BESS) while recovering the consumed energy back to the grid, dramatically reducing testing costs compared to resistive load banks. Q Sine’s regenerative load banks provide precise, programmable loading for commissioning.

Regenerative Electronic Load Bank - Q Sine Energy

We offer regenerative load Bank with 40KVA to 600KVA ratings suitable for DG and UPS load testing.

  • Used as load bank in UPS, DG and other electrical product load testing by feeding back the energy to Grid. This saves more than 95% of the energy losses and reduces heat loss improving safety
  • Used to replace conventional Resistive load bank to save energy and improve safety

What Our Valued Client Say About Us

For our pharma manufacturing unit, Q Sine implemented hybrid solution which gave us desired savings.
Fresenius Kabi India Pvt. Ltd.Project Incharge
With the installation of 2 x 600 A Active Harmonic Filters the harmonics level has been reduced to less than 3% complying to IEEE 519:2014 and now we are having stable PF. Thank you Q Sine.
Schaeffler India Ltd.Electrical Consultant ​
We were looking for savings by addressing harmonics related issues and Q SINE installed latest technology of 3 level Active Harmonic Filters at our plant. We are very happy achieving our savings goal in one Sugar season. Also, Our maintenance team have reported lesser failures.
Shahu SugarChief Engineer
Every textile industry faces acute harmonics issues. Q SINE installed 2550A AHF to mitigate our Harmonics issues and compliance to IEEE 519:2014. Now our operations suffer lesser interruption.
