Description

High Voltage DC Electronic Loads – The HVL Series from B&K Precision

The HVL Series DC electronic loads offer a wide operating voltage of up to 1000 V and feature a high-power density, providing 6 kW in a 5U form factor. These loads are suitable for automated test equipment (ATE) system applications and can handle a variety of dynamic loading conditions for evaluating DC-DC converters, batteries, battery chargers, photovoltaic arrays, and other high-power DC sources.

In addition to constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CW) operating modes, the HVL Series includes capabilities for continuous, pulse, and toggle transient operations, allowing precise switching between two load levels. The advanced list mode programming feature simplifies the setup and execution of complex load sequences directly from the front panel.

For applications requiring more power, up to ten identical HVL Series models can be connected in parallel, increasing total sink capabilities to 60 kW. The operating software also allows for remote instrument control and monitoring from a PC. Additionally, separate battery test software facilitates battery discharge testing with data logging capabilities.

Built-in remote PC interfaces include USB (USBTMC-compliant), LAN, and GPIB, all supporting SCPI commands. The front panel USB host port enables direct data logging to a connected flash drive.

*1 Applies when set voltage (CV mode) or set current (CC mode) is greater than 0.2% of full scale.

*2 The slew rate specifications are not warranted, but are descriptions of typical performance. The actual transition time is defined as the time for the input to change from 10% to 90%, or vice versa, of the programmed current values. In case of very large load changes, e.g. from no load to full load, the actual transition time will be larger than the expected time. The load will automatically adjust the slew rate to fit within the range (high or low) that is closest to the programmed value.

*3 Tested and certified by a Nationally Recognized Testing Laboratory (NRTL), accredited by OSHA.
