High-speed electronic DC load.

The EL 2000 HS (high-speed) electronic DC load from Intepro Systems is the latest addition to its growing family of power system automatic test equipment (ATE). 

The EL 2000 HS Series is a stand-alone 40W 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 device-under-test (DUT). In addition, the EL 2000 HS is designed for sub-1V 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 50MHz measurement bandwidth with a 150MS/s, 14-bit digitizer. Measurements include voltage, current, power, noise, settling time and overshoot/undershoot for both V and I. The standard 20V/20A/40W module can sink 20A with only 0.3V applied to the load head. In constant-current mode the module achieves 40A/µs rise time with a 20A 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.

DC power source auto-ranging capability.

Intepro Systems has published a technical note describing the benefits of auto-ranging in power conversion equipment test applications.  

Unlike DC sources that provide rated power only when maximum voltage is applied to the load, DC power sources equipped with an auto-ranging output stage are capable of delivering higher output current at reduced voltages. This feature is especially useful when testing products that require varied input voltages while maintaining regulated output power. With auto-ranging, a single, smaller power source can often be used to address low- and high-voltage/current requirements.

The two-page technical note uses an example of the production test of a 2.5 kW DC/DC converter to demonstrate the versatility of an auto-ranging programmable DC source. The DC/DC converter must be tested for operation over both high- and low-input voltage conditions. A single 3 kW auto-ranging source handles all test conditions. With a standard power source, a larger 5 KW programmable source would be required.

New website launched

New website with improved sales and service functionality

Intepro Systems have gone live with a new website offering greater levels of functionality for visitors. The new website is the latest development in a restructuring of the company that has seen Intepro recently relocate their European HQ to a new facility in Sandhurst, (GB), appoint Simon Tanner to the role of UK Sales Manager, have Nicky Charles take on the role of UK and Europe Support Manager and sees Colin Sycamore change roles from European Sales Manager to the new position of Global Service Manager to provide the highest level of service to the large installed customer base and the growing list of new installations.

In addition to providing comprehensive information on Intepro’s products and markets full information is available on their support services including installation and relocation, calibration, project management, training courses, test programmes, fixtures and software updates. The key new area on the website is a management function for customers to register system faults, monitor repair processes and outcomes.

Derek Somers, European Sales Manager of Intepro comments, “The launch of our new website is a response to the continued growth of our business. It offers improved functionality and will develop continuously to provide new and existing customers with enhanced sales and support features. Intepro has been supplying ATE solutions all over the world for nearly 30 years. The mission critical nature of our test systems means that fast, efficient service and visibility of the process is essential to our customers and we are pleased to be able to provide this new management tool on our re-launched website.”
