High-speed DC load solves point-of-load converter test challenges
Tustin, CA. Intepro Systems has announced the EL 2000 HS (high-speed) electronic DC load as the latest addition to its family of power-system automatic test equipment (ATE). The EL 2000 HS Series is a standalone 40-W load module providing point-of-load (POL) connections and point-of-use (POU) for fast-slew-rate DC loading.
Ever-higher switching speeds and lower operating voltages present unique challenges in testing POL/POU power-conversion systems. In response, the EL 2000 HS load offers a smart on-board load head that minimizes inductance, resistive losses, and noise, which pose serious problems with loads using wires to connect the load to the DUT. In addition, the EL 2000 HS is designed for sub-1-V testing to meet the demands of low-voltage devices.
The EL 2000 HS’s standalone modular POU design, along with its smart on-board load head, allows for positioning the load to DUT without the need for customization. The standard load offers four programmable modes of operation: constant current, constant resistance, constant power, and constant voltage. All have a 50-MHz measurement bandwidth with a 150-MS/s, 14-bit digitizer. Measurements include voltage, current, power, noise, settling time, and overshoot/undershoot for both V and I. The standard 20-V/20-A/40-W module can sink 20 A with only 0.3 V applied to the load head. In constant-current mode the module achieves 40-A/µs rise time with a 20-A load for high-speed pulse loading when conducting real load simulation of high-bandwidth devices. Ethernet control allows for easy operation by utilizing either Intepro’s PowerStar software package or third-party software.
“The EL 2000 HS electronic load’s smart on-board modular head design minimizes inductance that would otherwise interfere with accurate testing of high-speed load transitions,” said Gerard Sheehan, Intepro’s chief technical officer. “By adding the benefits of high-speed control and sampling, Intepro’s electronic loads are able to provide full functionality for your product testing needs.”
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.
