Simple to use powerful electronic load offers constant current/power/voltage/resistance modes

Saelig Company has introduced the Model PT04-FC 3kW Electronic Load which has been specifically developed to accommodate the testing of fuel cells as well as low-voltage power supplies, including 24V telecommunications power systems and supplies. The load is simple and intuitive to operate and is housed in a 4U 19" rack-mount case, with two quiet temperature-controlled fans mounted on the front panel to provide forced air cooling. The rugged, reliable design of the device provides constant current control from 0A to 120A on the 24V range setting and 0A to 60A on the 48V setting, with constant power, constant resistance, and constant voltage also available as standard operational modes, accessible via ATE/remote control. Weight has been minimized for easy transportation. The model is also useful as a general-purpose variable electronic load. It is rated to operate continuously over the specified current and voltage ranges. The standard model offers a differential 0V-5V input for simple control systems, or the input can be paralleled for larger systems. A typical application might consist of an external DC power source to be tested (e.g. an individual battery, or battery pack, a power supply, or a telecomm rectifier) connected to the device’s DC power connectors, with the remote control box connected to the load. More than one device load can be connected in parallel.
