Electronic Load tests power sources in diverse applications.

Press Release Summary:




Bench top Model UPEL-2500 electronic load simulator is based on high-speed current transformer providing feedback to lateral MOSFETs. Average power rating is 2,500 W and maximum rating is 4,000 W. Unit features voltage range from 1-200 V peak to peak and current up to 100 A. Internal generator allows dynamic testing of many power sources. Dynamic loading capability is up to 1 KHz in ac/dc mode and up to 20 KHz in dc mode. Manual and remote control modes allow integration with ATE systems.



Original Press Release:



Universal Power Electronic Load has Higher Ratings



The UPEL-2500 is a bench top electronic load simulation system is being introduced by Electronic Design and Research, Inc. of Louisville, Kentucky USA. It is a universal tool for testing power sources in diverse industrial production, repair shops and instrumentation laboratories. The manufacturer claims their new system offers up to four times the power rating of existing loads in the same or higher cost ranges. The operating principle is based on a high-speed current transformer providing feedback to powerful lateral MOSFETs, ensuring low EMC, susceptibility and delivering precise control of the UPEL-2500's output characteristics. The UPEL-2500 was designed for testing power supplies, transformers, amplifiers and components. It combines features such as low noise level operation, temperature-controlled fans, automatic cutouts at over-current, over-power and high-temperature points, and the following:


  • Manual and remote control modes for easy integration with ATE systems.


  • An internal generator (Sine, triangle or tooth waves) allows dynamic testing of many power sources.


  • Constant current, constant resistance, constant voltage and constant power modes


  • Power rating is 2500W (average) and 4000W (maximum). Voltage from 1-200V, peek to peak and current up to 100 amperes


  • Dynamic loading capability is up to 1 KHz in AC/DC mode and up to 20 KHz in DC mode.


  • Measurements: Voltage (average and peak to peak), current and power.


  • APG - analog programmable interface: load, control signal and input oscillator enables, and output voltage, current and power for ATE feedback.


  • Three large LCD displays to monitor current, voltage and power.


The new EDR UPEL 2500 was conceived to meet the widest range of high power unit testing requirements in such fields as telecommunications, automotive and appliance manufacturing, aviation, materials handling, transportation systems, military, railroad and marine applications.
