Overview
The 8614 Programmable DC electronic load provides the performance of modular system DC electronic load 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 behaviour 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 8614 provides standard USB (USBTMC-compliant), GPIB, or RS-232 serial interfaces for remote communication.
To ensure the reliability of your testing, the 8614 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.
