The 8500 series Programmable DC Electronic

Loads can be used for testing and evaluating a

variety of DC power sources. Their wide oper-

ating ranges of up to 500 V and 240 A, flexible

operating modes and excellent measurement

accuracy make the 8500 series 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 while voltage/current or resistance/power

values are measured and displayed in real time.

Load terminals are isolated and floating.

Extensive protection, including over tempera-

ture, over power, over voltage, over current and

reverse polarity will help protect your valuable

prototype.

The DC loads are easy to use. All parameters

can be set quickly and precisely from the front

panel, or programmed via RS232 or USB inter-

faces.

When selecting a DC load, it is important to

consider not only voltage and current

requirements, but also power ratings. The power

used when testing must fall within the hatched

region for the appropriate DC load.

Some applications may require high voltage/low

current and low voltage/high current which a

single load may not be able to handle. B&K

Precision’s broad range of DC loads will allow

you to select the optimal model for your

requirements.

Voltage and current can be set to a maximum resolution of 1 mV and 0.1 mA respectively (models 8500 and 8502 only). Up to 25 different instrument setups can be stored and recalled from internal memory.

(CC) mode can be used for load regulation testing of DC power supplies or for characterizing the discharge profile of a battery. Constant Power (CP) mode simulates a load whose power consumption is independent of the applied voltage.
