Chroma offers two new AC and DC electronic load series. The 63800R offers AC electronic loads with regenerative capability, featuring three models with power ratings of 9kVA, 12kVA, and 15kVA. This series offers a high-power density design, providing a maximum load capacity of 15kVA within a compact 3U chassis.
To accommodate higher power rating test requirements, it’s possible to parallel multiple units for increased load capacity while using the master-slave control.
Additionally, Chroma presents the 63700 Series Regenerative DC electronic loads are suitable for product reliability testing in various applications — including electric vehicle (EV) battery discharge, fuel cell discharge, high-power power supply aging, DC EV supply equipment (EVSE), unidirectional on-board chargers (OBC), fuel cell systems, energy storage systems (ESS), AC/DC and DC/DC power supply burn-in tests, and various power electronics applications.
These regenerative DC loads can simulate a range of load characteristics while also feeding energy back to the grid, providing an efficient and sustainable solution that reduces test environment temperatures and power conversion electricity costs.
The 63700 Series offers high power density within a compact 3U form factor, with power ratings reaching up to 18kW per unit and currents of up to 120A. Users can parallel up to 10 units for a maximum power of 180kW and a maximum current of 1,200A. Voltage options include 600V, 1,200V, and 1,800V.
All models in the series come equipped with external signal control functionality, allowing for the simulation of real current waveforms. Master/slave control enables parallel operation of identical 63700 units for synchronized dynamic loading. The system can store up to 256 programmable sequences, which can be loaded at any time, reducing test duration and increasing throughput during automated testing.
