New high-power regenerative AC electronic load from Chroma (+datasheet)

December 01, 2023

Chroma Systems Solutions, a provider of battery and power conversion test solutions, has released their latest Regenerative AC Electronic Load, the Chroma 63800R Series. It features three models with power ratings of 9kVA, 12kVA, and 15kVA. To accommodate higher power test requirements, multiple units can be paralleled for increased load capacity.

It has an efficient energy-saving solution for a broad spectrum of renewable energy applications including ESS, hybrid PV inverters, AC EVSE, and bidirectional on-board chargers (BOBC) for V2L and V2H applications. The regenerative feature, in contrast to traditional AC loads, eliminates wasted heat generation which significantly reduces energy costs. The new series also meets IEC 62040-3 standard requirements for UPS testing.

The Chroma 63800R series utilizes advanced all-digital control technology and introduces a Stand-By function to handle rapid fluctuations in the voltage source of the device under test (DUT). This function keeps the load in an active state when the DUT is off or in standby so that it can instantly start drawing power when the voltage source is activated. According to Chroma, this functionality lends itself well to the implementation of fully automated testing.

In addition to basic functions such as CC, CP, and CR, the 63800R AC loads offer advanced operating modes like Rectified and Phase Lead/Lag mode. It can also simulate SCR and TRIAC component characteristics with a unique Half-Cycle Load function.

The 63800R series features a 5″ LCD display with an intuitive user interface for easy operation. Connect with USB, LAN, and optional GPIB or CAN interfaces for remote and digital control with a PC and Chroma SoftPanel software. Additionally, Chroma provides instrument drivers for LabVIEW-integrated system control.
