Chroma 63800R Series offers AC electronic loads with regenerative capability, featuring three models with power ratings of 9kVA, 12kVA, and 15kVA. This series boasts a high-power density design, providing a maximum load capacity of 15kVA within a compact 3U chassis. To accommodate higher power rating test requirements, you can parallel multiple units for increased load capacity while utilizing master-slave control.

The Chroma 63800R Ser ies presents a highly efficient energy-saving solution with its regenerative feature, making it ideal 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.

In contrast to traditional AC loads for UPS testing, the 63800R Series eliminates waste heat generation, significantly reducing electricity costs due to its regenerative capability. Furthermore, i t meets the requirements of the IEC 62040-3 standard 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 in standby or off and instantly starts drawing power when the voltage source is activated. This functionality lends itself well to the implementation of fully automated testing in smart factories.

In addition to basic functions such as CC, CP, and CR, the Chroma 63800R Series offers advanced operating modes like Rectified and phase Lead/Lag mode. It can also simulate SCR and TRIAC component characteristics with its unique half-cycle load function.

The 63800R Series features a 5″ LCD display with an intuitive user interface for seamless operation. Connectivity options include USB, LAN, and optional GPIB or CAN interfaces for swift remote and digital control via a PC using Chroma’s SoftPanel software. Additionally, Chroma provides instrument drivers for LabVIEW-integrated system control.
