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 540A. Users can parallel up to 10 units* for a maximum power of 180kW and a maximum current of 1,200A. Voltage options include 100V, 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. T hese attributes make it an ideal test solution for design verification and integration into automated test systems.
