24kW Electronic Loads can be Paralleled and Synchronized
Chroma has just released the 63224A 24kW DC Electronic Load from its new 63200A series of high-power dc loads. Designed for testing a wide range of power conversion products including ac-dc and server power supplies, dc-dc converters, EV batteries, automotive charging stations, and other power electronics components, these loads can be synchronously paralleled up to 480kW and dynamically synchronized for generating complex multi-channel transient profiles. The 300% peak overpower capability provides extra headroom for fault condition simulations in automotive batteries, and fuel cells.
The ultra-high density power (6kW@4U) not only saves room, its super high voltage (0.015%+0.015%F.S.) and current (0.04%+0.04%F.S.) measurement accuracy ensures the dependability of test results. In addition, the entire series can either be operated by hand or controlled remotely. For higher power demands, master/slave control can be used to parallel multiple units for operation. These electronic loads also have synchronous loading capabilities to simulate actual loading status.
Features of these electronic loads include: Highest accuracy found in any high-power dc load; Highest power density available (6kW @4U); The sine wave loading function allows for the setting of a current bias (I_DC), a loading sine wave (I_AC), and the sine wave frequency; User defined waveform (UDW) and external signal control functions to simulate real world current waveforms; Auto frequency dynamic sweep function; The digitizing function allows for the recording of both voltage and current waveforms; Complex operating modes including CR+CC, CV+CR and CV+CC modes; Smart pwm fan speed control reduces unnecessary fan noise; Vacuum Fluorescent Display (VFD) display avoids heat problems found in other displays.
