BK 8514B 1500W Programmable DC Electronic Load

Description

BK 8514B, part of the BK 8500B Series programmable DC electronic loads, improves on its previous model (BK 8500 Series) whilst remaining dependable and affordable. This series supports both SCPI and older protocols.

These DC loads have a transient mode speed of up to 10 kHz and feature various input terminals for banana plug or spade connectors. They are perfect for testing DC power supplies, DC-DC converters, batteries, battery chargers, and solar panels.

*1 Fast pulse trains with large transitions may not be achievable.
*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.
