High-power electronic load PLI series

DCprogrammableRS-232

Description The PLI series of electronic loads provide a comfortable operation by a graphical user interface. The PLI series highlight is the extensive variety of standard interfaces. Apart from Ethernet, USB, RS-232 and Analog interface there is a standard CAN interface. Programming is done in SCPI syntax. Functions The units provide constant current mode, constant voltage mode, constant power mode and constant resistance mode. In addition, protections for current and voltage can be set in any mode. A static data acquisition function allows to store measurement data on an external USB flash drive. Dynamic operation can be configured by up to 300 list point settings. The Electronic Load saves the synchronously acquired measurement data with timestamp. A configurable trigger model controls data acquisition, static and dynamic settings. Zero-Volt Models - PLIxxxxZV Special applications, such as fuel cell tests, need to load the DUT down to almost 0 V. For these purposes we supply a range of models with an integrated zero-volt supply. Special Functions •Energy Storage Test/Discharge Function An implemented test function enables discharging energy storages such as accumulators, batteries, ultracaps etc. in an easy way and supplying determined values like charge and energy. •Internal Resistance Measurement Measurement of the internal DC resistance of energy storage systems such as batteries, accumulators, capacitors, as well as cables, power supplies and so on. •Watchdog Function When the watchdog function is activated, the load input is switched off in the event of a faulty communication with the control PC in order to protect the connected test item.
