How do electronic loads work?

Written on August 1, 2017 at 7:20 am, by

Electronic loads are used in a variety of tests, including power supply tests and battery tests. You can program them to provide exactly the kind of load that you need for the device you are testing. One of the most common ways to use an electronic load is in the constant current (CC) mode. In […]

Electronic Load Selection: Volts, Amps, and Model Numbers

Written on May 15, 2017 at 9:43 am, by

Often the selection of programmable power supplies is based upon how high a voltage it can produce or how much current it can source. When selecting an electronic load, however, you need to consider not only volts and amps, but power as well. For example, the SLH-500-6-1800 has a maximum input voltage of 500 VDC […]

Know Your Electronic Load Modes

Written on November 11, 2016 at 7:29 am, by

Electronic loads, such as the Sorensen SL Series of DC Electronic Loads, are instruments that you would use to provide a programmable load when testing voltage and current sources, including power supplies and batteries. Modern electronic loads are actually sophisticated electronic test instruments that can offer a number of different modes, including Constant Current (CC) […]

Generate Fast Transient Tests with an Electronic Load

Written on June 23, 2016 at 8:30 am, by

To ensure that automotive electronics can withstand the voltage transients induced on the power bus, companies use expensive arbitrary waveform generation and coupling networks during the design phase. For production test, however, a simpler and less expensive means for simulating bus voltage variations and transients is required. For many transient tests, all you need is […]

Application Tips for Electronic Loads

Written on February 1, 2016 at 7:22 am, by

Modern electronic loads, such as the AMREL SL Series, are versatile test instruments that should be part of every test engineer’s toolbox. Here are some tips on how to use them properly. Operating Modes Electronic loads operate in one of four different operating modes: Constant current (CC) mode. Most electronic loads are used in constant-current […]

Choose the Right Electronic Load

Written on August 20, 2015 at 7:20 am, by

Electronic loads have many different applications, including testing power converters and modulating a current supply while performing other tests. They are easy-to-use and provide much higher throughput than resistors when varying loads are needed. When choosing an electronic load, the most important specifications that you need to consider are the voltage rating, current rating, and […]

Use electronic loads to increase test throughput

Written on June 9, 2015 at 11:28 am, by

You can use electronic loads to test many different devices, including AC and DC power sources, power converters, inverters, uninterruptible power supplies (UPSes), and electrochemical sources, such as batteries and fuel cells. Electronic loads, such as the Sorensen SL Series, shown in Figure 1, are much easier to use than a bank of power resistors […]

Simulate high-brightness LEDs when testing drivers

Written on May 4, 2015 at 7:12 am, by

One of the challenges facing designers of lighting fixtures or luminaires that use high-brightness LEDs (HBLEDs) is testing the low-voltage, constant-current power supplies, called drivers, used to power the LEDs. Making this choice is difficult because the number of LEDS and the configuration of the LEDs will vary from design to design. To test HBLED […]
