The new “B” Series units are a major upgrade to the company’s EL 9000 Series, packing a complete suite of test features and controls in a 3U rack panel – 50% smaller compared to the former models.
A special feature is an FPGA-based digital function and arbitrary profile generator enabling user-customisable load profiles. Advanced DSP hardware offers improved analog and digital interface response time. The unit features current rise time as fast as 18µsec, 10-90% load – ideal for testing pulsed power supplies. Intuitive manual operation is provided via the unit’s large, color touch panel controls.
The EL 9000 B Series offers four common regulation modes: constant voltage, constant current, constant resistance and constant power. In parallel operation of multiple devices, a master-slave bus is used to link the units to an integrated system. Optional, pluggable digital interface modules for CANopen, Ethernet (1 or 2 ports), Profibus, ProfiNet I/O (1 or 2 ports), RS232, DeviceNet and ModBus-TCP are available.
“The built-in function generator provides users with exceptional flexibility in creating test profiles,” said Gerard Sheehan, Chief Technical Officer, Intepro. “This is especially important in reproducing non-linear internal resistances, such as those needed in testing batteries and LED lighting systems.”
