8550 Series Programmable DC Electronic Loads - 1

Data Sheet The 8550 Series DC electronic loads provide many features and capabilities typically found in performance instruments, at a value price. Capable of sinking 350 W in a compact benchtop form factor, this series is well equipped for testing and evaluating power supplies, DC-DC converters, batteries, battery chargers, and photovoltaic arrays. Static operating modes include constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CW). Configurable list, transient, and automatic test modes offer dynamically changing load conditions for evaluating a variety of DC sources. Additionally, the dedicated battery discharge mode simplifies battery testing with configurable stop conditions. Load behavior can be triggered internally, externally, or remotely. Operating software and battery test software are provided for remote PC control and monitoring through the RS232 interface. The general-purpose handler interface offers pass/fail feedback and simplifies integration with PLC devices, commonly found in production and manufacturing environments. Measurement data and other parameters can be logged directly to a flash drive connected to the front panel USB host port. Advanced power supply characterization The 8550 Series offers several built-in functions for evaluating DC power supplies including: ■ Sweep test ■ Load regulation test ■ Protection limit test Features and benefits ■ High power density, up to 350 W in compact 2U half-rack form factor ■ Transient mode up to 20 kHz in CC mode ■ CC/CV/CR/CW operating modes ■ Front-panel remote sense terminals ■ List mode programming ■ Automatic test mode ■ Overvoltage (OVP), overcurrent (OCP), Overpower (OPP) protection, remote reverse voltage (RRV), and ke_y-lock function ■ Thermostatically-controlled fans for quiet operation ■ Short-circuit test ■ CR-LED mode to simulate the loading behavior of typical LEDs ■ Configurable battery discharge test ■ Adjustable voltage/current slew rate ■ Front panel USB host port for logging measurement data ■ Save/recall instrument settings to internal memory ■ Analog current monitoring BNC output ■ Operating software and battery test software provided ■ 4.3-inch LCD screen ■ RS232 and Handler interfaces Technical data subject to change © B&K Prec

8550 Series Programmable DC Electronic Loads - 2

Programmable DC Electronic Loads 8550 Series Operation highlights List mode Transient operation Automatic test mode The 8550 Series list mode is highly configurable for generating precise load sequences. Transient operation enables the DC load to periodically switch between two load levels. Automatic test mode enables these DC loads to execute multiple test sequences. fail Width-B Each list mode program contains up to 100 user programmable steps. Save up to 10 list mode program files directly to internal memory for quick recall. Step parameters include current limit, step duration, and slew...

8550 Series Programmable DC Electronic Loads - 3

Programmable DC Electronic Loads 8550 Series The 8550 Series features three test modes specifically for evaluating the performance of DC power supplies. ■ Load regulation test - Calculates the load regulation (%) of a power supply under test by applying a sequence of minimum, normal, and maximum load conditions. The calculated internal resistance (Rs) of the connected power supply is also displayed. ■ Sweep mode - Offers a simple way to capture overshoot and undershoot of a power supply by applying two configurable load levels at a swept frequency. The resulting maximum overshoot (Vp+) and...

Programmable DC Electronic Loads 8550 Series Note: All specifications apply to the unit after a temperature stabilization time of 30 minutes over an ambient temperature range of 23 °C ± 5 °C. Readback Voltage (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...
