Chroma 63800R Regenerative AC Electronic Load

Overview

Chroma 63800R Regenerative AC Electronic Load series includes models 63809R, 63812R, and 63815R with rated powers of 9kVA, 12kVA, and 15kVA respectively. The series is a regenerative switching-type AC load that uses bidirectional power source technology to feed energy back to the facility power grid with up to 89% efficiency. Electrical specifications include a Voltage Range of 30Vrms - 350Vrms, a Frequency Range of 30Hz - 100Hz, and a maximum load capacity of 15kVA. Model-specific ratings are: 63809R-350-87: 350V / 87A / 9kVA; 63812R-350-96: 350V / 96A / 12kVA; 63815R-350-105: 350V / 105A / 15kVA. The 63800R Series is packaged in a 3U chassis achieving high power density and supports parallel operation of multiple units with master-slave control for increased load capacity. User interface and connectivity features include a 5″ LCD display, a touchscreen UI, USB and LAN connectivity, and optional GPIB or CAN interfaces. Operating modes and functions provided are CC, CP, CR, Rectified modes, CC Lead/Lag and CS Lead/Lag (inductive/capacitive simulation), a half-cycle load function for SCR/TRIAC simulation, single/three-phase functionality, an advanced all-digital control architecture, a Stand-By fast response function, and software support via A638003 Softpanel and LabVIEW drivers. Available accessories and options listed are A618005 Single/Three Phase Switching Unit, A620039 GPIB remote interface, A620045 CAN remote interface, and A638003 Softpanel for the 63800R Series. The 63800R Series is described for higher-power renewable energy applications including ESS, hybrid PV inverters, AC EVSE, and bidirectional on-board chargers (BOBC) for V2L and V2H. Its regenerative capability and high power density are positioned as an energy-saving solution for AC EVSE testing. Explicit testing applications cited include AC EVSE testing (dynamic load testing, OCP/OPP load testing, and card-swipe charging tests), load startup and backup power switching tests for inverters and UPS systems, and UPS testing where the series meets the IEC 62040-3 standard. For AC EVSE testing the product notes that a dedicated Inrush Current Limiter Box is required, and a single unit operating at full load +power is claimed to save 116,946 kWh of electricity per year, equivalent to reducing 45,258 kg (99,777 lbs.) of carbon emissions.
