Regenerative AC and DC Electronic Loads
From R&D validation to high power system testing
Caltest Instruments provides regenerative AC and DC electronic loads for accurate, efficient testing from bench to full system level.
Our regenerative AC/DC electronic loads support a wide range of applications and provide accurate, efficient testing from bench to full system-level validation. Caltest Instruments offers high-performance solutions from leading manufacturers such as Pacific Power and EA Elektro-Automatik.
AC electronic loads support up to 1250 Vdc and 350 Vrms AC. You use them to test AC sources, inverters, UPS systems, and grid tied equipment. Regenerative and unidirectional models give flexibility and reduce energy loss.
DC electronic loads support batteries, power supplies, DC DC converters, fuel cells, and inverters. The EA ELR Series delivers 1.5 kW to 30 kW per chassis and scales up to 3.84 MW. Energy recovery reaches >96% energy, reducing heat, noise, and HVAC costs..
Perform R&D, production, and compliance testing with lower energy use and high performance.
