Quantel Chroma - Model 63700 Series -Regenerative DC Electronic Load
The Chroma 63700 Series Regenerative DC Electronic Load is engineered for rigorous product reliability testing across various applications, including electric vehicle battery discharge and fuel cell systems. Designed for efficient energy management, the load can simulate diverse load characteristics and recycle energy back to the electrical grid, thus reducing both the test environment temperature and HVAC power consumption. It features a compact 3U form factor, offering high power density with power ratings up to 18kW per unit and a current capacity of up to 120A. Supporting parallel operation, users can combine up to 10 units for a total of 180kW power and 1,200A current capacity. It provides voltage options of 600V, 1,200V, and 1,800V. For precise testing control, the series can store up to 256 programmable sequences and comes equipped with various interfacing options including LAN, USB, GPIB, and CAN. Comprehensive protective features ensure reliable operations, making it an ideal choice for design verification and integration into automated testing systems.
Chroma 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 wide range of load characteristics while also feeding energy back to the grid, providing an efficient and sustainable solution that reduces test environment temperatures, HVAC power consumption, 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.
Regarding measurement capabilities, the 63700 Series can perform real-time and precise voltage and current measurements. With the TFT touch display and rotary knob on the front panel, the 63700 Series offers convenient operation and setup. These units can also be controlled via LAN, USB, GPIB, or CAN.
Additionally, the 63700 Series features overcurrent, over-power, and over-temperature protection functions, as well as an overvoltage alarm mechanism, ensuring product reliability during testing. These attributes make it an ideal test solution for design verification and integration into automated test systems.
