Programmable DC Electronic Loads

8600 Series

Technical data subject to change

www.bkprecision.com

The 8600 Series programmable DC electronic

loads provide the performance of modular system

DC electronic loads in a compact benchtop form

factor. With fast transient operation speeds and

high 16-bit measurement resolution, these

standalone DC loads can be used for testing and

evaluating a variety of DC sources such as DC

power supplies, DC-DC converters, batteries,

battery chargers, and photovoltaic arrays.

The DC loads can operate in constant current

(CC), constant voltage (CV), constant resistance

(CR), or constant power (CW) mode and be

conﬁgured to provide a dynamically changing

load to the DC source with fast load switching

times. Versatile internal, external, and remote

triggering options allow the dynamic load

behavior to be synchronized with other events.

Increase productivity by saving your test

parameters into any one of the 100 memory areas

for quick system recall. All load parameters such

as voltage, current, slew rate, and width can be

set via the front panel or programmed remotely.

The 8600 Series provides standard USB

(USBTMC-compliant), GPIB, or RS-232 serial

interfaces for remote communication.

To ensure the reliability of your testing, the 8600

Series provides a power-on system self-test and

numerous protection features: overtemperature

(OTP), overvoltage (OVP), overcurrent (OCP),

overpower (OPP), and local/remote reverse

voltage (LRV/RRV) protection.

Special applications

The 8600 Series provides a built-in battery

test mode to measure the ampere-hour (Ah)

characteristic of a battery and a unique

CR-LED mode to simulate the loading

behavior of a typical LED.
