DC electronic load 8551

programmableRS-232with USB interface

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. Configurable list, transient, and automatic test modes offer dynamically changing load conditions for evaluating a variety of DC sources. The dedicated battery discharge mode simplifies battery testing. 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 List mode programming Automatic test mode Overvoltage (OVP), overcurrent (OCP), Overpower (OPP) protection, remote reverse voltage (RRV), and key-lock function Thermostatically-controlled fans for quiet operation Short-circuit test Configurable battery discharge test CR-LED mode to simulate the loading behavior of typical LEDs Adjustable voltage/current slew rate Operating software and battery test software provided
