Ultra High Power Density and Scalable to 480 kW
The 63200A series high power DC electronic loads are 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 units can be synchronously paralleled up to 240kW 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, fuel cells, and more.
The 63200A series have three operating voltage choices, 150V, 600V & 1,200V, with models covering power levels from 4kW to 24kW and up to 2,000A in a single unit. And each model of the 63200A series has 3 power ranges allowing for precise measurement of voltage and current in real time. Since short circuit testing is one of the essential power testing items, the 63200A series provides short circuit simulation to effectively solve the application demands for power and automated testing.
The DC loads have unique user defined waveform (UDW) capability and external analog modulating input for simulating real-world, custom waveforms. Another distinct feature is the dynamic auto-frequency sweep function, which enables detecting a UUTs worst case output deviation across a wide range of current frequencies. In addition, a 255-set of data storage function has been built in for recall of the stored settings at any time. For automated testing, the save and recall functions can save a great deal of time.
The embedded PWM fan speed control reduces noise caused by fans. The 63200A series also have overcurrent, overpower, and over temperature protections as well as over voltage and polarity reverse alarms to enhance product reliability. These DC loads are reliable products for engineering testing and automated test system's integration.
Master/Slave Parallel Control
When there is a need for increased power, two or more loads can be run in parallel to achieve the desired load current. The 63200A provides smart Master/Slave mode controls that allows the user to program the load currents at the Master and have them automatically calculated and downloaded to the slave loads. Using several loads in parallel to emulate a single load dramatically simplifies operation. All models of the 63200A series can be integrated into a 41U standard rack to save space. The 63200A can be controlled and reconfigured with automated testing applications via USB (standard), GPIB and Ethernet/LXI (optional) interfaces.
Battery Discharge Testing
The 63200A has three discharge modes: CC, CR and CP. The electronic load can set cut off voltage and time (1~100,000 sec.) to end loading correctly and make sure the battery is not damaged due to over discharge. In addition it can measure the battery discharge power (WH, AH) and total discharge time. For example, when Load ON is pressed, the 63200A internal clock will start counting until the battery voltage drops to its cut off voltage or Load OFF is pressed. The battery discharge tests can also apply to super capacitors for discharge time testing.
Remote Softpanel Operation
The 63200A series loads can be operated either from the front panel controls or from an available softpanel. This user friendly software includes all the functions of the 63200A series loads and is easy to understand and operate. The 63200A loads can be controlled via standard USB, or optional Ethernet and GPIB interfaces, for remote control and automated testing applications such as Data Centers, Server Power, High Voltage UPS, Telecom Power, Solar Power, On-Board Battery Chargers and Battery Packs, Energy Storage Systems and EV Charger Stations.
