The ‘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-customizable 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 flexibility in creating test profiles which is important when reproducing non-linear internal resistances, such as those needed in testing batteries and LED lighting systems.”
Intepro Systems offers electronic loads as stand-alone units or as complete test systems. Maintenance contracts and onsite calibrations are also available for its test systems.
