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
