The 8550 Series DC electric 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 evaluation 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.
Features:
- High power density, up to 350 W in compact 2U half-rack factor
-Transient mode up to 20 kHz in CC mode
- Front panel remote sense
- List mode programming
- Overvoltage (OVP)
- Overcurrent (OCP)
- Overpower (OPP) protection
- Remote reverse voltage (RRV)
- Key-lock function
-RS232 and Handler interfaces
