The 8500B Series programmable DC electronic loads improve upon all aspects of its predecessor while maintaining dependability at a value price. This series supports both SCPI and the backwards compatible legacy protocol. With a transient mode speed of up to 10 kHz and multi-type input terminals for banana plug or spade connectors, these DC loads are suitable for testing and evaluating DC power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays. Maximum input power up to 1500 W CC/CV/CR/CW operating modes Transient mode up to 10 kHz in CC mode 16-bit voltage and current measurement system with up to 0.1 mV / 0.1 mA resolution List mode and adjustable slew rate in CC mode Short circuit test Built-in battery test function with voltage level, capacity level, and timer stop conditions CR-LED mode to simulate the loading behavior of typical LEDs Remote voltage sensing to compensate for the effect of voltage drop in wires Analog current control and monitoring TTL (DB9) interface, includes TTL to USB adapter (models 8542B, 8500B, 8502B, 8510B) USB and RS232 interfaces (8514B only) OVP/OCP/OPP/OTP and local/remote reverse voltage (LRV/RRV) protection
