Data Sheet Programmable DC Electronic Loads 8500B Series Features and benefits (cont.) The 8500B Series programmable DC electronic Special applications n Adjustable slew rate in CC mode loads improve upon all aspects of its predecessor while maintaining dependability at a value price. Performance verification of photovoltaic n Flexible triggering options via front panel, A set of comprehensive functions make these solar panels external input, timer, or bus loads a versatile tool for testing and evaluating CR-LED mode to simulate loading behavior n Built-in battery test function, specify cut-off DC power supplies, DC-DC converters, batteries, and test LED drivers voltage, capacity level, and time battery chargers, and photovoltaic arrays. Fuel and solar cell tests n Test modes to validate the OCP/OPP protection List mode, transient mode, automatic test mode, functions of a power supply Battery test and power supply evaluations and battery test mode offer a variety of test tools n OVP/OCP/OPP/OTP including local and remote for lab or production line applications. reverse voltage (LRV/RRV) protection Continuously switching and pulsing load Features and benefits n Remote sense conditions put a dynamically changing load on n Maximum input power 600 W DC sources. Load behavior can be triggered n Short-circuit test n CC/CV/CR/CW operating modes internally, externally, or remotely from the n Analog current control and monitoring included application software. n 16-bit voltage and current measurement system n Two thermostatically controlled fans providing up to 0.1 mV / 0.1 mA resolution (linear-speed control to minimize noise) Contained in a compact benchtop form factor, n Transient mode up to 10 kHz in CC mode these loads operate in constant current (CC), n TTL (DB9) interface with USB adapter constant voltage (CV), constant resistance (CR), n List mode function for custom step sequences n Integrated meter measures voltage, current, & or constant power (CW) mode. Internal memory n Supports both SCPI and backwards compatible power allows for 100 sets of user configurable 8500 series protocol parameters such as voltage, current, slew rate and n Rack-mountable n Store and recall up to 100 instrument settings width for quick system recall.
