The B+K Precision BK85xx series devices are programmable DC electronic loads. They can be used for testing and evaluating a variety of DC power sources. The instruemts' wide operating ranges (up to 500 V and 240 A), flexible operating modes and excellent measurement accuracy make them well suited for characterizing DC power supplies, DC/DC-converters, batteries, fuel cells and solar cells. The loads can operate in CC, CV, CR or CP mode (constant current, voltage, resistance and power) while voltage/current or resistance/power values are measured and displayed in real time. Load terminals are isolated and floating. The devices offer over-temperature, over-power, over-voltage, over-current and reverse polarity protection.

  • Programmable, electronic DC loads.
  • Power depending on model 150 W to 1500 W.
  • CC (constant current), CR (constant resistance), CV (constant voltage) and CP/CW (constant power) operation.
  • Models with wide voltage and current range, 0...500 V, 0...240 A.
  • 16 bit voltage and current measurement system providing up to 0.1 mV/0.1 mA resolution.
  • Transient mode up to 10 kHz in CC mode.
  • List mode function for custom step sequences.
  • Store and recall up to 100 instrument settings.
  • Adjustable slew rate in CC mode.
  • Flexible triggering options via front panel, external input, timer, or bus.
  • Built-in battery test function, specify cut-off voltage, capacity level, and time.
  • Test modes to validate the OCP/OPP* protection functions of a power supply.
  • OVP/OCP/OPP/OTP* including local and remote reverse voltage (LRV/RRV) protection.
  • Remote sense.
  • Short-circuit test.
  • Analog current control and monitoring.
  • Two thermostatically controlled fans (linear-speed control to minimize noise).
  • Integrated meter measures voltage, current, and power.
  • USB to TTL serial converter cables (except BK8514B) and application software included. BK8514B with USB and RS232.
  • Supports both SCPI and backwards compatible 8500 series protocol.
  • Rack-mountable.

* OCP Over-current, OVP over-voltage, OPP over-power and OTP over-temperature protection.
