B&K Precision HVL100050 – High Voltage DC Electronic Load (1000 V, 50 A, 6 kW)

• CC/CV/CR/CW operating modes
• Continuous, pulse, and toggle transient operation
• Transient mode speed up to 10 kHz in CC mode
• Advanced list mode programming
• Adjustable loop response speed

The HVL Series DC Electronic Loads offer a wide operating voltage up to 1000 V and high-power density providing 6 kW in a 5U form factor. In addition to CC/CV/CR/CW operating modes, the HVL Series features continuous, pulse, and toggle transient operation. Up to 10 identical HVL Series models can be combined in parallel to increase total sink capabilities to 60 kW.

Suitable for ATE system applications, this series supports a variety of dynamic loading conditions for evaluating DC-DC converters, batteries, battery chargers, photovoltaic arrays, and other high-power DC sources.

The HVL Series DC electronic loads are offered in multiple output configurations to suit a variety of testing conditions. Note the different form factor for the higher-current products.

Each list mode program contains up to 100 user-programmable steps. Save up to 10 list mode programs directly to internal memory for quick recall. Step parameters include current limit, step duration, and slew rate. List mode programs can be set to repeat a maximum of 100,000 times. BOST / EOST (Beginning / End of step Trigger) can be enabled for any step in the list to generate output triggers for synchronizing events with other externally connected instruments. List mode programs can be configured and run from the front panel or remotely using the provided application software.

For applications requiring more power, up to 10 identical HVL Series DC load models can be connected in parallel to increase the maximum sink power to 60 kW. Once configured, the connected units will display the voltage and current of the complete system.

Transient operation enables the DC load to periodically switch between two load levels.

Transient – Continuous

Switch continuously between A and B load current levels where rise/fall slew rates and level width can be adjusted.

Transient – Pulse

Upon enabling the input, the load executes one pulse cycle returning to Level-A and waits to receive a trigger signal before executing another pulse.

Transient – Toggle

The DC load current will switch between Level-A and Level-B following receipt of a trigger signal.

• PC software is provided for generating and executing test sequences and measurement data logging without the need to write source code
• Log voltage, current, power measurements, and export data in spreadsheet format for further analysis
• Configure and run transient operation, list mode, and more

The HVL Series can operate at low voltages for applications in fuel cell and solar cell testing.
