These conventional programmable electronic loads in the attractive tower housing, with a powerful microprocessor controller and 16 bit ADC/DACs for a high resolution. The DC input area is extremely flexible and allows the use at high input voltages or, alternatively, high input current, in the framework of the respective nominal power. For a comfortable use, this series have a high-resolution, intuitive TFT touch panel with built-in function generator with pre-defined curve forms (triangle, rectangle, trapezium, sine, ramp, arbitrary) as well as an automatic battery test. The display resolution is 4 dig. In the range from 0 to 100% adjustable DC input parameters (U, I, P, R) have a high accuracy and stability, with fast current rise times and are practically free of ripple (FET-linear amplifier). For the remote-controlled operation, the devices via standard USB. An isolated 3-way interface (analogue 0-5 V/0-10V, USB and Ethernet/LAN) is available as an option and can be easily retrofitted. This device series is an indispensable tool for lab table, for the realization of repeatable test results. As a free and pay would be available operator software EA power control, enables semi-automated test routines.This text is machine translated.
